Comment: Psilocybe caerulipes is unique in that it is the only active Psilocybe native to the NE United States. It is a wide ranging species but uncommonly found. The Bethany strain reportedly fruits in both the spring and fall. In deciduous forests on hardwood slash and debris, plant matter, on or about decaying hardwood logs, birch, beech and maple. It is often overlooked as just another little brown mushroom, and although widely distributed, it is not found often. It is sometimes confused with the larger Psilocybe ovoideocystidiata.
