Habitat: MARTINIQUE, Lorrain River, 100 m altitude, 1 Jun 1975, Fiard 318 (holotype K(M) 84366, as Psilocybe yungensis by Pegler). Discussion: Psilocybe zapotecocaribaea belongs to section Zapotecorum because of the subellipsoid, thin-walled spores and bluing stipe tissues of the basidiomata. This collection originally was studied and considered by Peglera (1983) as Psilocybe yungensis Singer & A.H. Smith. However Psilocybe yungensis has distinctly rhomboid or subrhomboid, thick-walled basidiospores and belongs in section Cordisporae. Psilocybe zapotecocaribea is somewhat similar to Psilocybe zapotecoantillarum but differs by the cheilocystidia that are not branched and rarely lageniform in Psilocybe zapotecoantillarum. Psilocybe zapotecocaribaea also has white floccose scales covering the stipe, which are lacking in Psilocybe zapotecoantillarum. Psilocybe zapotecocaribaea also should be compared to Psilocybe ramulosum (Guzmán & Gononi) Guzmán. Psilocybe ramulosum differs from Psilocybe zapotecocaribaea in highly branched cheilocystidia and pleurocystidia that are longer than found in Psilocybe zapotecaribaea (15-35 (-45) µm long; Guzmán 1995). source - www.mycologia.org [95 (6): 1176-1178] Pictures at www.mushroomobserver.org |
