Psilocybe chuxiongensis T. Ma & K.D. Hyde, Phytotaxa 156(4): 213, 2014

This species is found in subtropical habitats of central Yunnan Province, and characterized by hemisphaeric to hemisphaeric-convex pilei, the absence of annulus, large ellipsoid, elongate-ellipsoid to subhexagonal basidiospores (13–16 × 8–10.5 × 7.5–10 μm) and a coprophilous or subcoprophilous habitat. It is closely related to the wide-spread subtropical species P. cubensis (Earle) Singer and the pantropical species P. subcubensis Guzmán because of the similar basidiomata and microscopic characteristics (basidiospores, pleurocystidia and cheilocystidia), as well as having a similar habitat ( Guzmán 1983, 1995).
