Description
- Cap: 2 – 4 cm, often with small wrinkles, hygrophanous, dark brown when moist drying to ochre buff. Often with a darker zone around the margin as it dries.
- Gills: Broad, not crowded, adnexed, dark brown.
- Stipe: 4 – 6 cm x 4 – 6 mm, pruinose, cartilaginous, the same color as the cap or pale ochre.
- Spores: Dark purplish brown, rough. 12 — 16 x 7 — 9 micrometers, almond shaped, verrucose, with small germ pore.
- Odor: Rather strong.
- Taste: Unpleasant.
- Microscopic features: Basidia four spored, pleurocystidia look like basidia and are dark brown, cheilocystidia abundant, fusoid-ventricose or subcylindric.
Habitat and formation
Panaeolina castaneifolia grows in along roadsides and grassy fields. This species was first found in New York City and is probably more widely distributed. This mushroom is often mistaken for Panaeolina foenisecii, and has similar microscopic features but can be distinguished by its thicker stem and more unpleasant taste. It also resembles Panaeolus subbalteatus and can be distinguished from that species by its roughened brown spores.
