Abstract
A revision of the North American spp. of the genus Volvariella Speg., which contains agarics having pink spores, free lamellae, and a volva, recognizes 18 accepted spp., 2 of which contain 2 vars. and 5 imperfectly known spp. Nomenclatural innovations are Volvariella canalipes (Volyariopsis c. Murr.), V. earlei (Volvariopsis e. Murr.), V. alabamensis (Volvariopsis a. Murr.), V. iamaicensis (Volvariopsis j. Murr.), V. bakeri (Volvariopsis b. Murr.) V. peckii (Volvaria p. Atk. in Pk.), V. cubensis (Volvariopsis c. Murr.), V. alachuana (Volvariopsis a. Murr.), V. hypopithys (Agaricus h. Fr.). Volvariopsis flaviceps Murr. is reduced to Volvariella bombycina var. flaviceps, and the new Volvariella smithii, from Washington, is described.
