Plant Permits and Endangered Species
TWO SYSTEMS OF PLANT PERMIT REGULATIONS issued by the U.S. Fish and Wildlife Service are now in effect. For activities involving export, and in certain cases import, of named plant taxa in some 46 families, regulations for the Convention on International Trade in Endangered Species of Wild Fauna and Flora (and the list of taxa) were published in the February 22, 1977 Federal Register 42(35, IV): 10461-10488. An application suggestions leaflet (C-1) is also available.
For activities involving export, import, and interstate commerce of plants to be listed under the Endangered Species Act of 1973, regulations appeared in the June 24, 1977 Federal Register 42(122, II): 32373-32381. An application aid leaflet is in preparation. Although no plants are yet listed under the Act, herbaria can apply under both regulations now.
To obtain copies of the two final regulations and apply for permits contact: Federal Wildlife Permit Office, U.S. Fish and Wildlife Service, Washington, D.C. 20240; telephone 202/634-1496.

During the past six months, the average time for regular-type manuscripts was 5 months and for short communications was 4 months, after acceptance of revised manuscripts.
Several SHORT COMMUNICATIONS have been published and others are in review or in press. These can be incorporated into certain issues without delay in publication of regular articles.
Two SPECIAL PAPERS have been published and one is in press. The Editorial Board believes such papers enliven the Journal and we will continue to publish an occasional Special Paper. Any member may submit a manuscript and ask that it be considered for inclusion as a Special Paper and the Editorial Board may also solicit such manuscripts. A Special Paper could be 1) a review article of limited scope and general interest, 2) evaluation and critique of research evidence on a controversial subject,
32
3) recent advances in a specialized research area, 4) over-view of major research contributions to plant science. Heretofore, the Editor has selected articles for this category from submitted papers. Members of the Editorial Board would act as reviewers in some instances and would make final selections. Special papers should be the same length as regular articles.
5. I would like to express my continuing sincere appreciation to all reviewers. I am impressed with their cooperation and dedication. Without their assistance, the editorial tasks would be virtually impossible to accomplish.

CANNELL, M. G. R. AND F. T. LAST (eds.). Tree Physiology and Yield Imrpovement. Academic Press, London. (U.S. Edition: Academic Press, New York). 1976. 567 pp., illust. £.15.00.
This book is a compendium primarily of review papers presented at a conference on physiological genetics and forest tree yield held near Edinburgh, Scotland, 1975, under the auspices of I.U.F.R.O. Conference objectives were to examine physiological and morphological characteristics limiting wood yield, the underlying inherent differences in forest tree yield and heritability of characteristics that may be exploited by breeding. Papers presented emphasized physiology rather than genetics as there have been few heritability studies on physiological attributes of trees. The papers are divided into 6 groups; carbon-fixation efficiency, shoot and cambial growth, water stress, frost hardiness, mineral nutrition, and problems concerning use of physiological selection criteria. Specific topics dealt with are photosynthesis and growth models and various factors affecting photosynthesis including enzymatic criteria and carbon fixation efficiency. Tree and stand form was examined from the standpoint of genetic differences in canopy characteristics, tree forms and the environmental conditions and mechanisms influencing them, inherent differences in shoot growth, photo-periodic response, shoot and leaf development and bud break. The role of plant hormones in regulating shoot elongation, diameter growth and crown form, leaf-cambium relations and the relation of leaf cell dimensions and tracheid diameters on potential wood production were also explored.
The prospect of making selections among trees based on water relationships has potential in yield improvement. Breeding for drought resistance is explored and the physical parameters for drought resistance examined. Oxygen trans-port and oxygen deficiency on wet sites is also discussed. Frost hardiness as an adaptation factor to consider in tree selection and various aspects of this physiological phenomenon are reviewed. Two papers deal with the role of tree nutrition as a genetic trait. The role of mycorrhizae in nutrient uptake and the implications for compatible genetic matchings between mycorrhizal fungi and tree host were examined. This particular aspect of yield improvement looks promising and will hopefully be receiving more research emphasis.
Finally, papers are presented concerning the problem of physiological selection criteria. These papers address competition as a factor influencing yield improvement, maternal effects on early performance of tree progenies, and other variations in morphological and physiological characteristics of trees that have implications for tree improvement. In discussing physiological problems many of the papers use as an example the particular species the authors have studied. Most of the papers have extensive bibliographies leading a person interested in the topic to a wealth of current scientific knowledge. Readers of this book should find it a useful reference. The book should also prove valuable for courses in advanced physiology and genetics.

GARETH-JONES, E. B. (ed.). Recent Advances in Aquatic Mycology. Elek Science, London. 1976. 749 pp., illust. £ 21.00.
The editor of this volume, a noted British mycologist, gives two aims for the book: To bring together current reviews of topics devoted to aquatic fungi; to update the 1961 volume of Johnson and Sparrow (Fungi in Oceans and Estuaries). Both are successful.
This book consists of 27 papers divided into four sections, two on marine fungi—Ascomycetes, Fungi Imperfecti and Basidiomycetes and Lower Fungi—and two on freshwater fungi—Ascomycetes, Fungi Imperfecti and Basidiomycetes and Lower Fungi. Topics within each section are sufficiently varied so that a wide range of interests and specialties are reviewed, from ultrastructure and physiology to fungi in cooling towers or sewage. One chap-ter lists films on aquatic fungi available in Europe, Canada, and the U.S.
33
The chapters are replete with data presented as extensive tables, graphs, and photographs. The style of writing of the individual chapters is concise and to the point; evaluation of data is presented to a limited extent.
This reference will be of interest and value to the specialist in aquatic mycology and related fields and to those who wish to maintain a broad botanical library. It belongs in undergraduate and graduate libraries for obvious reasons; it could be used also to enhance the base of microbiology courses which usually contain precious little on microorganisms other than bacteria. Considering the falling rate of exchange of the pound, the high quality of reproduction and large size of this volume, this book is less expensive than many one-third its size.

RAVEN, PETER H., RAY F. EVERT AND HELENA CURTIS. Biology of Plants (2nd ed.). Worth Publishers, Inc., N.Y. 1976. xv + 685 pp., illust.
One of the challenges of teaching an introductory course is sometimes to give you just the right amount of information to tantalize the better students without completely losing the poorer ones. And so it must be for the authors of textbooks used in such courses. Raven, Evert and Curtis have succeeded in meeting this challenge; their Biology of Plants adequately covers the body of knowledge generally recognized as Botany, yet resists the temptation to be encyclopedic.
The style of writing is easy to comprehend, which is in part a reflection of Ms. Curtis' earlier efforts in writing for the introductory student. Key words are both underscored and italicized and often defined on the spot as well as in the excellent glossary. The abundant photographs and diagrams not only enhance the explanations offered in the text but should prove a boon to the harassed laboratory instructor with an overly large class. Unfortunately, some label lines blend with the background of the black and white photographs so as to make them unclear. Otherwise the editing of the book is excellent and errors are minimal.
When I first looked at the table of contents, it seemed to be an awkward arrangement of topics, because it differs so from my present text, but after having read the book in its entirety, I find it refreshingly different. Several con-current themes carry the topics logically from chapter to chapter, with evolution being a strong unifying theme throughout. In this way the review of the plant kingdom, for instance, is an integrated part of the text instead of having the appearance that it was added, just in case some-one would want to use the text for a two-semester course. The use of this book just might rejuvenate even my tired old lectures!

LEWIS, WALTER H. AND MEMORY P. F. ELVINLEWIS. Medical Botany. Plants Affecting Man's Health. John Wiley & Sons, N.Y. 1977. 515 pp., illust. $27.50.
Students of herbalist medicine have long awaited an authoritative book that interprets traditional folklore and herbal information in the light of modern clinical data on drugs and their source plants. Professionals have perhaps been apprehensive of such a book, expecting it to be a dangerous tool in the hands of an inexpert and adventure-some public. "Medical Botany" is the controversial realization of both these expectations.
The first section of the book effectively outlines the kinds of plant poisons and reviews the diverse kinds of injurious plants. Included are notes on the chemical structure of poisons and the physiology of poisoning. The second edition of the book comprises the structure and virtues of the known remedial plants. Review of modern, clinical data and commentary on the physiology of remedial action amplify the traditional recitation of virtues from herbals and Indian lore. The last section of the book covers the psychoactive plants. Such drugs as stimulants, hallucinogens, and depressants are discussed thoroughly from an informative cultural outlook. The book is provided with useful appendices, including a classification of the plant kingdom, a bibliography, and a glossary.
"Medical Botany" succeeds in bringing a much needed modern, clinical outlook to the traditional folklore of herbal medicine. Although the descriptions of plants included are useless for those eager to identify usable plants in the wild, the book should prove to be a valuable guide to the pertinent chemical compounds of plants—in the hands of botanists and physicians. The volume is especially helpful to botantists advising physicians on poisonous plants.

GRANT, VERNE. Organismic Evolution. W. H. Freeman & Co., San Francisco. 1977. 418 pp., illust.
Verne Grant has written a logical, readable, extensively documented survey of the evolutionary process Beginning with the basics of population genetics, including such microevolutionary processes as allele repacements under varying conditions of selective force and population size, the book gradually widens in scope to present the con-temporary understanding of the mechanisms of speciation and macroevolution. It is satisfying to see discussions of the latter processes presented in conjunction with the former, for too often macroevolution is glibly propounded with little regard for the underying processes. Next is a consideration of the evolution of humans, with emphasis on our phylogenetic and ecological background, pertinent selective forces and trends which shaped the human organ-ism, and the interplay between organic and cultural evolution that has made man what he is.
Grant pauses often to discuss various contemporary disagreements (such as the meaning and implications of orthogenesis and the relative roles of selection and drift) in a fair manner, but rarely fails to point out his own opinion and his reasons for holding it. Thus one reads not an undigested review of the field, but evolution as Grant perceives it, with wide latitude for skepticism and disagreement by the reader.
The book is replete with illustrations, examples and explanation of hypotheses and experiments, so that the reader gains a tangible grasp of the modes of inquiry as well as the concepts they produce. Grant assumes a general biological background on the part of the reader, including an understanding of basic Mendelian genetics. Thus the book is appropriate as a text for a course in evolution for college students, as an ancillary text for other courses, or as personal reading for anyone desiring an understanding of how the process of evolution is understood today and what questions are being asked by students in the field.

Barley Genetics III. Proceedings of the Third International Genetics Symposium, Garching (Germany). 1975. 849 pp.
This thick volume contains 135 scientific papers presented at the symposium, each by a different author or authors. Some of the topics covered are Biochemical Gentics, Mutation Induction, Chromosome Engineering, Breeding Techniques, Physiology of Kernel Yield, Selection Theory and Application. Most of the contributions are intended for specialists, but the opening address by the late G. A. Wiebe and the short closing speech by G. Fischbeck are of general interest to geneticists and plant breeders. Two points are emphasized. 1. The value of more sophisticated techniques as applied to breeding problems, and 2. the need for obtaining, maintaining a broad genetics base for breeding, consisting of a large gene pool.

BEATLEY, JANICE C. Vascular Plants of the Nevada Test Site and Central-Southern Nevada. Technical In-formation Center, Office of Technical Information, Energy Research and Development Administration, Springfield, Va. 1976. 308 pp. Available as TID-26881, $9.75 (foreign $12.15) from National Technical In-formation Service, U. S. Dept. of Commerce, Spring-field, Va. 22161.
Dr. Beatley's book, in large measure, represents information previously presented in a series of publications over a period of 16 years, during her association with the Laboratory of Nuclear Medicine and Radiation Biology at the University of California, Los Angeles. The availability of this information now, in a single text, plus new, included data, makes this book a valued reference.
In the first part of the volume the author characterizes the physical features and vegetation types as they occur over the more than 1,300 square miles of the Nevada Test Site. This large, government-controlled area within southern Nevada is geographically oriented so as to include portions of two Southwestern deserts. Thus, vegetation is classified and described as Mojave, transition or Great Basin, with an analysis of associations within each of these regions. The treatment is effective, logical and well documented. Twenty-five pages of black and white photographs follow, providing visual aspects of many of the vegetation categories de-scribed.
The second, and major, portion of the book is devoted to an annotated checklist of vascular plants. The value of this section is greatly enhanced by the inclusion of taxa occurring beyond the Test Site boundaries (the Test Site comprising only one-fifth of the total 8,000 square mile area represented). The list of 1,093 entries incorporates the latest nomenclatural changes and, for the traditionally taxonomically complex groups, reflects the interpretations of recognized experts.
As a whole, the book must be rated as an important contribution to the knowledge of Southwestern botany. Three main features combine to make it so: the careful work of the author, as reflected throughout the volume; the focus upon the botany of an uniquely interesting and largely inaccessible desert area; and the contribution it makes toward the eventual compilation of a flora for all of Southern Nevada, an area not presently treated in any current text.

1-IORIKAWA YOSHIWO. Atlas of the Japanese Flora II: An Introduction of Plant Sociology of East Asia. Bakken Co., Ltd., Tokyo. 1976. 3 pp. + 362 maps + I-XII (Indices). 35,000 yen (cloth, boxed).
An elegant oversized book, Volume II follows essentially the same format as Volume I. All pages are de-voted to Spermatophytes while the preceding publication included some Pteridophytes and Bryophytes. The first 8 illustrated pages are devoted to 3 families of Gymnosperms; the next 195 to 59 families of Archichlamydeae; the next 148 to 25 families of Monochlamydeae; and the last 11 to 25 families of Monocots. A total of 362 taxa are represented. A short discussion of methods is found on page 8. Each page contains the scientific name of the taxon, of each common synonym, and of the family. The common and family names appear in Japanese "Katakana" and in Roman letters. The life form (modified from Braun-Blanquet and Ellenberg) and general distribution are given. The illustrations consist of an aerial neap of Japan and neighboring regions with dots, each representing a "geoquadrat" (10 minutes in latitude and 15 minutes in longitude), to indicate locations of the taxon. In addition there are 2 other diagrams indicating elevational distributions: one between meridians 120° and 146° across Japan, and the other between parallels 24° and 46° as one moves from north to south.
The diagrams illustrating elevational distributions are very interesting. This volume will be extremely useful to phytogeographers, plant sociologists, and ecologists who wish to make comparisons of life forms, habitats, etc., between vicariads of Japan and other regions.

WEILGOLASKI, F. E. (ed.). Fennoscandian Tundra Ecosystems; Part 1. Plant and Microorganisms. Ecological Studies, Vol. 16. Springer-Verlag, N.Y. 1975. 366 pp., illust.
These studies of northern European tundra ecosystems add another geographical link to our understanding of an important circumpolar biome. F. E. Wielgolaski has assembled thirty-nine papers on the function and organization of tundra ecosystem in Norway, Finland and Sweden. As Part 1 (Plant and Microorganisms), this volume deals mainly with site decriptions, abiotic variables, primary production, decomposition and nutrient cycling. The Table of Contents for Part 2 (Animals and Systems Analysis) is given in the beginning of this volume. Both Parts 1 and 2 represent research funded through the International Biological Programs (IBP) in Norway, Finland and Sweden. Therefore, a large amount of information on Fennoscandian tundra ecosystems is here made available in English for comparison with similar IBP tundra studies in Canada, the United States, Russia and Great Britain. The authors of most of the papers presented here make some effort to compare their results with those of workers in the United States and Canada.
As an abstract and ambiguous term, `tundra' includes a multitude of ecosystems. Recognition of this variation is treated effectively in these Fennoscandian studies. Here, tundra is broadly defined as approximating areas with mean annual air temperatures below 0° C. In Norway, Finland and Sweden this definition includes all alpine zones (low, mid and high) as well as the subalpine birch zone and even subarctic woodands of pine and birch. Hence the presence of tree-form plants in the vegetation does not preclude its classification as tundra. Arctic tundra is found in northern
35
Finland, but these studies do not include this type. At least twelve different tundra ecosystems were studied intensively. However, most of the studies reported here were conducted on six types at Hardangervidda, Norway; dry meadow, wet meadow, lichen heath, willow thicket, birch forest and snow bed. In addition, intensive ecosystem analyses were carried out in a pine forest, three birch forests and a low alpine heath at Kevo, Finland and in a bog at Stordalen, Sweden. This vegetational heterogeneity in alpine study areas, associated with variations in snow cover, drainage and elevation, presents problems to intensive IBP projects which usually center around one 'representative' ecosystem (i.e., Wet Meadow at Barrow, Alaska). Measurements of productivity and decomposition across the Fennoscandian gradient of tundra variation is a herculean task which has been well accomplished in the present volume.
Presumably one of the important goals of the IBP is to obtain an understanding and estimate of productivity for whole tundra landscapes. In separate studies at Hardangervidda, Norway, the tundra vegetation was classified and mapped and the productivity of some of the map units was determined. However, these studies were not synthesized here into an overall estimate of landscape productivity.
The diversity of ecosystems and sites studied, together with the wide range of topics and organisms covered in this volume do not leave the reader with an overview of the functioning of Fennoscandian tundra systems. Not all the papers contrbiute to such an understanding: a paper on plant colonization of glacial morraines is interesting but out of place and another on the effects of grazing might be more appropriately placed in Part 2. A number of papers deal with the physiology of moss or lichen species which grow at the study sites. These arc concerned more with the physiological adaptations of individual species to the tundra environment than with the functioning of the whole system. However, the detailed consideration of cryptogams and their contribution to production is impressive.
The diverse papers are pulled together and integrated to some extent by an introductory chapter to each section and an initial site description which presents a long table giving most of the climatic, soil, vegetational and productivity data for each site. The fact that F. E. Wiclgolaski is the main or co-author of at least one-fourth of the papers also lends continuity. Each of the papers in this volume deals with actual results in a concise and succinct way. Long descriptions of methods and philosophical approach are avoided and the data is presented in well-organized tables and graphs. Unfortunately there are few pictures aside from about 12 photographs of the study sites in the first chapter.

BURNS, GEORGE W. The Science of Genetics. An Introduction to Heredity. 3rd Edition. Macmillan Publishing Co., N.Y. 1976. $13.95.
This introductory genetics text is well suited for the motivated student with better than average intellect. The introductory chapter is superb; it provides a stimulating glimpse of the field by discussing organisms of experimental interest, methods of investigation, and specializations within genetics. Chapters on probability and statistics pro-vide information prerequisite to mastery of classical genetics (the introductory student, often at the sophomore level, should appreciate these discussions). Sections of the book dealing with classical and population genetics are liberally infused with refreshingly different illustrations of genetic phenomena. Examples with historical significance have been retained. Each chapter lists a substantial number of questions with answers provided in the appendices. The frequent use of references provides students with a convenient introduction into the literature and stresses the experimental nature of genetics. Appendices include descriptions of the life cycles of selected organisms of significance to genetic investigation. Unfortunately the diagrams accompanying these descriptions, although neatly reproluced, are pedestrian and unstimulating. Illustrations and photographs throughout the remainder of the book, how-ever, are of good to excellent quality, providing useful amplification of topics. The addition of color could be a stimulating addition to this and many other genetics books.
There are, however, features that recommend the book less highly. Index and glossary, extremely important to students, are weak. Far more index entries refer to authors than to subjects (reasonable until the paucity of subject entries is noted). Subject headings are rarely subdivided for efficient use. The chapter on regulation of gene expression would most certainly need supplementation as it is out of date; although it considers histones, it omits discussions of important molecular constituents (e.g., heterogeneous nuclear RNA, poly-A, non-histone chromosomal proteins) and concepts (e.g., posttranslational modification of polypeptides, maturation and transport of transcript). Also, the addition of diagramatic 'descriptions explaining experimental techniques in molecular genetics would supplement the present approach and benefit students (most of whom have had only rudimentary exposure to chemistry, biochemistry or physics at the time they enroll in introductory genetics). Another instance of deficiency concerns macromolecular structure and nemy within the chromosome, as well as reiterated and unique DNA sequences. As with any text, individual instructors will have to evaluate for themselves whether the level of precision and discrimination between hypothesis and fact are acceptable. On the whole I feel that this book ranks highly as an introductory text to classical and population genetics and somewhat lower in molecular genetics.

MONTGOMERY, F. H. Seeds and Fruits of Plants of Eastern Canada and Northeastern United States. University of Toronto Press, Toronto and Buffalo. 1977. 232 pp. $25.00.
The distinctive characteristics of seeds are well known to plant scientists. Until now, however, there has been no good book which allows the identification of a large number of seeds (including seeds that are technically fruits) of native and introduced species. Professor Montgomery's book is a welcome reference.
The keys are based on the length/width ratios along with a chart of characteristic shapes and are simple to use. When they don't work there are more than 1,100 excellent black and white photographs to help. The illustrations are of exceptionally good quality considering the problems of obtaining clear photographic details of 3-dimensional objects.
The book should be in every library and laboratory where taxonomic work is involved. Wildlife specialists will be especially pleased as it will facilitate the difficult task of identifying the seeds from the crops of birds and the

stomachs of animals. In addition to being a useful reference, the artful photographs display the wonderful array of sizes, shapes, seed coat sculptures and textures displayed among the flowering plants.
The book is an odd size, 10" deep and 7" high which lies open on a table but may cause problems on the book-shelf. Also, if the genera and species in the keys contained page numbers referring to the text and illustrations, it would save the extra step of referring to the index each time a seed was keyed out.

VIERECK, LESLIE A. AND ELBERT L. LITTLE, JR. Atlas of United States Trees. Alaska Trees and Common Shrubs. Volume 2. United States Government Printing Office, Washington, D.C. 1975. 19 pp. text, 82 pp. maps $3.10.
LITTLE, ELBERT L., JR. Atlas of United States Trees. Minor Western Hardwoods. Volume 3. United States Government Printing Office, Washington, D.C. 1976. 13 pp. text, 210 pp. maps. $9.10.
These two volumes are part of what will become a five-volume Atlas of Trees and Shrubs of the Continental United States and Alaska. Volume I, "Conifers and Important Hardwoods", was the first of the series. To be completed at a later date are Volume 4, "Minor Eastern Hardwoods", and Volume 5, "Florida Trees".
Volume 2 contains maps showing the natural ranges of 82 native woody species found in Alaska. The range of each species is shown clearly by brown lines and dots on a black and white base map of the state at a scale of 1:10,000,000. Within the range, locality records are designated by brown circles. Similar brown circles designate areas outside of the main range where the species is known to exist in restricted populations. Also included in Volume 2 are 23 general maps providing information on climate and geography.
Volume 3 contains 8 by 11 inch maps of 210 tree species found in the west that were not included in Volume I. All species are represented on a base map of the Western United States by brown shading at a scale of 1:10,000,000. A base map of North America is added for those species whose range extends into Mexico or Canada. Small populations outside of the main range are shown by small brown circles, and an X indicates where one of these populations has recently become extinct.
The objectives of the series to show accurately where each woody species can be found have been well fulfilled. The maps show where each species can be found for study, collection of seed, or for identification. Although the Atlas is primarily of interest to foresters, the series should also prove valuable in areas such as ecology and land use planning.

COBLEY, L. S. AND W. M. STEELE. An Introduction to the Botany of Tropical Crops. 2nd Edition. Long-man, London. 1977. 371 pp. illust. $12.50 (paper).
Since a large percentage of the world's people are living in tropical lands, their basic food plants are of more than casual interest to plant scientists living in more temperate climates. Interest-provoking photographs of these plants, information on their preparation for use, their nutritional value, and their storability and palatability can provide the student with an appreciation of the problems of survival in lands whose histories are being written in today's newspapers. The first edition of this book was revised primarily by W. M. Steele who added a good deal of classical floral and fruit morphology, information rarely obtain-able in most texts. Unfortunately, the utility of the book is limited by the apparent assumption that the audience would be familiar with the plants. Neatly executed line drawings of floral morphology do not provide the North American reader with any idea of what the mangosteen, the guava, or nutmeg and mace look like as growing plants. Many photographs are muddy. I found very little information that is not in Shery's "Plants and Man".

GRUND, DARRYL W. AND KENNETH A. HARRISON. Nova Scotian Boletes. J. Cramer, FL-9490, Vaduz, Germany. 1976. DM 60. (Available from Lubrecht & Cramer, 152 Mountainside Drive, Randolph, N. J. 07801). 283 pp., 68 plates. $19.50.
The relatively recent surge in popularity of wild mush-rooms has brought about a need for new treatments based on modern taxonomic concepts of the North American species. Many boletes are edible, but the difficulty of identifying the species has deterred many from collecting and studying them. Several regional treatments have appeared in the last decade. To these can now be added this work on the boletes of Nova Scotia. The authors adopted the approach of collecting, taking detailed notes on habitat, size, color, odor, taste of fresh material, and then following with detailed microscopic and microchemical studies on the voucher specimens. They provide detailed descriptions, line drawings of microscopic structures and black-on-white photographs of some 80 species of the common species of Nova Scotia. A synoptic key and a dichotomous key are provided to aid identification. Their taxonomy is conservative; ten genera are recognized: Boletus (38 species), Boletellus (2 species), Boletinellus (1 species), Fuscoboletinus (5 species), Gyroporus (2 species), Leccinum (4 species), Pulveroboletus (1 species), Strobilomyces (2 species), Suillus (17 species), and Tylopilus (8 species). Informative introductory information on methods of collecting and subsequent study, and on morphology and terminology are provided.
