"Trichomycetes are fungi that live obligately in the digestive tract of adult or larval arthropods including insects, crustaceans, and millipedes. In recent years this group has attracted the attention not only of mycologists, but also of entomologists, invertebrate pathologists and other biologists interested in symbiotic relationships. Many new genera and species have been discovered in new hosts from many parts of the world during the last two decades.

This book illustrates and describes all current 55 genera and provides names and references to their 226 species. Also included are historical comments, keys to orders, families and genera, literature citations, lists of arthropod hosts and their fungal genera, major references to their symbiotic associations, a glossary, and a chapter on methodology.

The book is intended to help those who are interested in inventorying and identifying these gut fungi, and in understanding the basic biology of Trichomycetes."--BOOK JACKET.
