Description:The Inocybaceae is an ectomycorrhizal family of mushroom-forming fungi with some 1000 species worldwide. Seven genera are now recognized in the family but the last revision of North American taxa in the group took place nearly 100 years ago. Since this time the number of known species in North America has tripled and various estimates put the number of species in the family from this area between 300-400. This overview will present an introduction to the family Inocybaceae some evolutionary and ecological background and showcase recent systematic developments in the group. About Brandon Matheny:Brandon Matheny is originally from Oklahoma where he earned a BA in history at Oklahoma State University. After a move to Seattle Washington Brandon caught the mushroom bug and got heavily involved with the Puget Sound Mycological Society for several years before being admitted to the botany graduate program at the University of Washington. In 2003 Brandon got his PhD in fungal systematics did a postdoc at Clark University for five years then was appointed as an assistant professor at the University of Tennessee in 2008 with the Department of Ecology and Evolutionary Biology. Now Brandon is a full professor and curator of fungi for the Tennessee herbarium serves as executive editor at Mycologia and coordinates the affairs of some 50 graduate students in his department. His group’s research interests include fungal systematics diversification and taxonomy of mushroom-forming fungi and they do a lot of field work! Currently Brandon has an NSF grant to revise the systematics of North American Inocybaceae.
