Rick’s talk will focus on introducing Agaricus and working through a framework for understanding patterns of diversity and relatedness in Agaricus, allowing recognition of important groups and facilitating species identification by beginning with groups. A “synoptic” key approach to groups is presented and advocated. Species representing common, important or interesting examples for each group, primarily emphasizing California and the West will then be presented along with tips, anecdotes and points of interest.
California probably has over 100 species of Agaricus, most but not all of which have been discovered and named. Our knowledge base has recently increased and this talk will update the “common knowledge” of Agaricus in California and the West.
Richard W. Kerrigan was born and raised in California. He became interested in Agaricus in 1971, while an undergraduate at the University of California, Santa Cruz. He earned a bachelor’s and a master’s degree at San Francisco State University (1976, 1982), a doctorate from University of California, Santa Barbara (1989), and was a postdoctoral fellow at the University of Toronto (1989-1991). His mentors include David Arora and Dr. Harry Thiers. From 1991-2017, Kerrigan held the position of Director of Research, U.S.A., with Sylvan Inc., the world’s leading producer of cultivated mushroom spawn, where he worked on breeding improved strains of cultivated mushrooms. His study of the diversity, taxonomy, systematics and phylogeny of wild species of Agaricus continues as a separate, independent area of research now extending over 45 years.
