Author: Richard W. Kerrigan

Richard W. Kerrigan became interested in Agaricus in 1971, while an undergraduate at the University of California, Santa Cruz. A ubiqitous poisonous Agaricus growing there, superficially resembling the edible "Meadow Mushroom" Agaricus campestris, proved impossible to identify using contemporary publications. This toxic species later turned out to be afflicted with a series of taxonomic problems. During his graduate study of Agaricus, under the mentorship of Harry Thiers at San Francisco State University (M.A. awarded 1982), he ultimately identified it to be Agaricus californicus, a species that had vanished from the literature for the better part of the 20th century. This particular species is now lectotypified in this volume.

In 1989 he was awarded a Ph.D. from the University of California, Santa Barbara, where he worked with Ian Ross, emphasizing experimental molecular methods to delimit species and establish relationships in Agaricus. A postdoctoral fellowship with James Anderson and Paul Horgen at the University of Toronto, Erindale, focused on gene mapping, population biology and germ plasm resource assessment in wild and cultivated Agaricus bisporus, the "Button Mushroom." This work led to an appointment in 1991 with Sylvan, Inc., the world's leading producer of cultivated mushroom spawn, where work on breeding improved strains of cultivated mushrooms continues today. Dr. Kerrigan has held the position of Director of Research, U.S.A., with Sylvan since 1993. His study of the diversity, taxonomy, systematic and phylogeny of wild species of Agaricus continues as a separate, independent area of research now extending over 45 years.

Agaricus of North America (Memoirs of The New York Botanical Garden Volume 114)

Often casually called "the Meadow Mushrooms," about 90% of Agaricus species actually reside in forest and other non-grassland habitats. All species exploit the partly decomposed remains of green plants. Some species are edible, even cultivated, whil...
