Summary:
Features include 1) a dry cap that is fuscous brown to ochraceous brown with a dark umber umbo, the cap surface appressed-fibrillose away from the umbo, 2) close broad gills that become ochraceous cinnamon to ferruginous with white fringed edges, 3) a somewhat bulbous, dry, fibrillose stem that is umber-fuscous-brown with a paler top, 4) an earthy odor, and 5) angular spores with a few scattered tubercles. The description is derived from Kauffman(1). It may be a synonym of Inocybe curvipes P. Karst.
Inocybe radiata was reported by Gamiet(1) for BC. There is a collection by L. Norvell from BC at the University of British Columbia. There are collections at the University of Washington from WA, ID, MA, and MI. It was noted by Kauffman(4) for MA and NY to NC and MI.
