The book has been divided into two parts. Part I comprises review chapters on trichomycetes - including the history, taxonomy, phylogeny, biogeography ultrastructure, and physiology of trichomycetes. Part II comprises a composite of topics. It begins with two chapters on insect-fungus associations (ant pathogenic fungi and bark beetle galleries) followed by a chapter on nematophagous fungi. Subsequent chapters deal with such diverse mycological topics as fungal endophytes, endolithic micoorganisms, aquatic ascomycetes and hyphomycetes, and mushrooms.
