Psilocybe ovoideocystidiata is a psilocybin mushroom in the section Stuntzae, having psilocybin and/or psilocin as main active compounds. It is closely related to P. subaeruginascens from Java, P. septentrionalis from Japan, and P. wayanadensis from India. This mushroom was first documented by Richard V. Gaines in Montgomery County, Pennsylvania in June 2003. Although it is sometimes confused with Psilocybe caerulipes, it can be distinguished by its rhomboid spores, larger stature, earlier fruiting season and membranous annulus.

[edit] Etymology
From the frequent ovoid both pleuro- and cheilocystidia.
[edit] Description
- Cap: 1 — 4.5 cm across, convex to subumbonate, chestnut or orangish brown to yellowish brown to pearly cream color, hygrophanous, glabrous, sub-viscid, translucent-striate near the margin, from slightly to highly undulated in maturity, with irregular yellowish, brownish, or bluish tones, sometimes white when dry. Flesh thick, pliant. Bruises blue and more notably, green, where injured.
- Gills: adnate attachment and range from whitish to rusty brown, lavender, or dark purple brown.
- Spores: Dark purple brown, rhomboid to subrhomboid in face view, subellipsoid in side view, thick-walled, 8 x 6 µm .
- Stipe: 1.5 – 9 cm by 1 – 7 mm, equal, somewhat subbulbous, hollow, base sometimes hypogeous, smooth at the top and often having small scales near the bottom, colored whitish with irregular yellowish, brownish, or bluish tones. The partial veil is variable, ranging from a thin cortina that leaves a barely perceptible annular zone, to a substantial membrane that leaves a fairly persistent annulus.
- Taste: farinaceous
- Odor: farinaceous
- Microscopic features: Two types of cheilocystidia and pleurocystidia are present.
[edit] Habitat and formation
Psilocybe ovoideocystidiata is common in the Ohio river valley. Often found in the woody debris of overflow areas, along rivers and streams, rarely in man-made mulch. They are most common from April to mid June but they occasionally fruit as late as November. It was first documented in Pennsylvania, its been found from Kentucky east to Ohio, West Virginia, Virginia New Jersey and most recently from Rhode Island, New York and Southern California.
