  • Cap/Pileus: 10-45 mm in diameter, brown with a sticky surface when moist drying to a pale bluish grey to white.

Microscopic feat.:
  • Basidio/Spores: 8-10 by 6-7 µm, subrhomboid to rhomboid.

Comment: Previously misidentified as Psilocybe caerulipes. Closer examination reveals that the Bethany collection is most likely Psilocybe ovoideocystidiata, which agrees with the identification proposed by Psilocybe expert, Gastón Guzmán. Psilocybe ovoideocystidiata is only known from Ohio, Pennsylvania and West Virginia.
This was the only species we provided that had not been directly assessed by our staff. It is our policy not to accept spore products from outside sources in order to maintain tight quality control and correct identification. Due to the rarity and exceptional documentation of the samples we made an exception. Unfortunately, without actual specimens to examine, staff misidentified the species. At the time we were unaware of the existence of the newly described Psilocybe ovoideocystidiata and made our identification based primarily on the location of the initial collection. We could not have guessed that another species would be found in an area previously only known for a single, native and active Psilocybe that shares the same habitat.
