Panaeolus foenisecii

The cap is 1 to 4 cm across, conic to convex, hygrophanous with a brownish colour when moist and tannish when dry, The gills are broad, adnate, brown with lighter edges, becoming mottled as the spores mature. pruinose, and slightly striate. It has a slightly unpleasant nutty fungal taste. The odor is nutty and slightly unpleasant. Microscopic features Spores measure 12–17 x 7–11 μm, subfusoid to lemon shaped, rough, dextrinoid, with an apical germ pore. Cheilocystidia subfusoid to cylindric or subcapitate, often wavy, up to 50 μm long. Pleurocystidia absent, but some authors report inconspicuous "pseudocystidia". The pileipellis a cellular cuticle with subglobose elements and has pileocystidia. This is probably why P. foenisecii is occasionally listed as a psychoactive species in older literature. == Habitat and distribution ==

It can be found throughout North America. In the Pacific Northwest of the United States, the species may be the most common to appear in recently fertilized lawns. It is also found on lawns along the East Coast. ==Biochemistry==
