Description
A brown gilled mushroom with a characteristically hairy stem base and very acrid flesh; it can cause gastrointestinal poisoning.
Identification features
The cap reaches 6 cm, brown, initially smooth and later somewhat wrinkled. Gills start pale and become brownish. The slender stem is yellowish to brown and hairy toward the base.
Identification checklist
Check the distinctly hairy stem base, brown cap and very acrid flesh. The older name Gymnopus peronatus is still commonly used.
How to separate similar species
Gymnopus dryophilus lacks the same hairy base and is listed as edible. Do not taste Collybiopsis peronata because of confusion risk.
Habitat
Grows in deciduous woodland on thick layers of decaying leaf litter, often in groups, from summer into early winter.
Fruiting period
August, September, October, November, December
