Cap: (10-) 15-25 (-45) mm diam, convex to subumbonate, lubricous to subviscid, glabrous, translucent-striate at the margin, hygrophanous, orangish-brown to yellowish-brown, sometimes becoming pallid white when dry and with age.

Gills: Subadnate, brownish pale to dark brownish-niolaceous, unifrom in color.

Stem: (15-) 25-60 (-90) X (1-) 2-5 (-7) mm, smooth above to floccose-scaly below, cylindrical, equal, womewhat bulbous, base sometimes hypogeous, whitish, with irregular pale ochre or violaceous tones below or pale reddish-brown above. Hollow, with white mycellium at the base. Annulus membraneous, white evanescent and context is whitish to ochrerous pale, bluing, odor farinaceous.

Spores: (7-) 8-9 (-12) X (5.5) 6-7 (-8.5) microns. Rhomboid or subrhomboid in face view, thick-walled.

Sporeprint: Violaceous dark.

Habitat: Gregarious on wood or wood debris, in trails or places with herbaceous plants in deciduous forest. Allong streams and riverbanks and in flooded plains areas.

Distribution: When Guzmán et al. wrote the paper, they were only aware of its occurrence in Pennsylvania. Presently it has since been collected in West Virginia and Ohio.

Season: Spring to Summer (mid April to late April through August-September.

Dosage: Probably very similar to P. cyanescens but maybe a little less potent.

Comment:Psilocybe ovoideocystidiata is described as a new bluing species from Pennsylvania, U.S.A. It belongs to section Stuntzii Guzmán of genus Psilocybe for its subrhomboid, thick-walled spores and its caerulescent basidioma with annulus. It is macroscopically very similar to Psilocybe caerulipes, a species that shares a similar habitat in sandy soils along streams and riverbanks on the east coast of the United States west to Michigan in the northern part of America.
