Panaeolus tropicalis is a potent and hallucinogenic mushroom which contains psilocybin.

The cap is less than 20 mm across, with a convex shape and an incurved margin when young. It is smooth and grey, often with a brown center and margin. The gills are adnexed and grey, with blackish spots. The stem is 5-12 cm tall, 2.5 mm thick, hollow, and slightly swollen at the base. The spores are dark violet black, ellipsoid, measuring 11 x 8 micrometres. The entire mushroom bruises blue where it is handled.

It can be differentiated from Panaeolus cyanescens by microscopic characteristics.
