Panaeolina castaneifolia is a rare and widely distributed little brown mushroom.
It has dark brown, coarsely roughened spores which resemble those of Panaeolina foenisecii.
- Cap: 2–4 cm (0.79–1.57 in), 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 (1.6–2.4 in) x 4–6 mm (0.16–0.24 in), 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.
- Edibility: Non-Toxic, potentially contains small quantities of psychoactive alkaloids.
