At one time, P cystidiosus was thought, incorrectly to be synonymous with P corticatus (Jong &
Peng (1975). This proposed synonymy led to the depositing of several mis-labelled strains into international culture libraries. P cystidiosus is taxonomically discrete from P corticatus. Currently, P
corticatus (Fr. :Fr.) Kumm. and P dryinus (Pers. :Fr.) Kumm. are considered synonyms.

Description: Cap convex to hemispheric, eventually plane, measuring 2-5 cm. broad, and cream
to dingy white in color. (P abalonus is reportedly darker colored. (See Bresinksi et al. (1987)).
Cap margin often irregular. Gills broad, sometimes widely spaced, strongly decurrent, with irregular edges. Stem thick, central or eccentrically attached and relatively short.
Distribution: From the eastern and southeastern United States (Louisiana, Mississippi, North Carolina), Taiwan and SouthAfrica. This mushroom is probably distributed throughout similar ecological
zones of the world.

Natural Habitat: The type collection made by Dr. O.K. Miller came from Red Maple (Acer
rubrum). Also native to Eastern Cottonwood (Populus deitoides), Sweetgum (Liquidambar
