Panaeolus tropicalis

Panaeolus tropicalis is a potent species of psilocybin mushroom. It is also known as Copelandia tropicalis. Description The cap is 1.5 — 2(2.5) cm and hemispheric to convex to companulate. The margin is incurved when young, clay-colored, often reddish brown towards the disc, hygrophanous, smooth, and grayish to greenish; it is translucent-striate at the margin when wet. It becomes blue when bruised. The gills are adnexed, distinctly mottled, and dully grayish with blackish spots. The stipe is 5–12 cm long, 2–3 mm thick, hollow, and vertically striate. It is blackish towards the base, greyish towards the apex, and pallid to whitish fibrils run the length of the stipe. The stipe is equal to slightly swollen at the base and lacks a partial veil. Panaeolus tropicalis spores are dark violet black to black, ellipsoid, and 10.5–12.0 x 7–9 µm. The basidia each produce two spores. The entire mushroom readily bruises blue where it is handled. It can be differentiated from Panaeolus cyanescens by microscopic characteristics. Habitat and distribution Panaeolus tropicalis is mushroom that grows on dung. It is most often found in Hawaii, Central Africa, and Cambodia; it can also found in Mexico, Tanzania, the Philippines, Florida, and Japan.
