Psilocybe ovoideocystidiata

Psilocybe ovoideocystidiata was first documented by Richard V. Gaines in Montgomery County in June 2003. It belongs to section Stuntzii Guzmán of genus Psilocybe for its subrhomboid, thick-walled spores and its caerulescent basidioma with annulus.

Psilocybe ovoideocystidiata is common in the Ohio river valley. It is often found in the woody debris of overflow areas, along rivers and streams.

This mushroom is closely related to Psilocybe azurescens and Psilocybe cyanescens but with one major difference: it fruits in spring and early summer, not in the fall. The mushrooms appear most common from April to mid June but they occasionally fruit as late as November. So if you have both azurescens and ovoideocystidiata in your lawn then you may be able to harvest fresh Psilocybe mushrooms spring, summer and fall!
