Inocybe lanuginosa (Bull.) P. Kumm.
Führ. Pilzk.: 80. 1871.

Common Name: none

• Description

  For description see Matheny & Kropp & 'California Mushrooms'.

• Habitat

  Solitary to scattered in duff under conifers, occasionally with hardwoods, or on rotten wood; uncommon, fruiting in fall along the coast.

• Edibility

  Unknown.

• Comments

  Inocybe lanuginosa can be distinguished by its small fruitbodies with fibrillose-scaly, brown to dark brown caps and stipes, dull brown gills, nodulose spores, and thick-walled pleuro- and cheilocystidia. It often grows on rotten wood, a substrate also typical for the nearly indistinguishable Inocybe leptophylla. The latter differs in forming slightly longer spores with more nodules and lacks pleurocystidia.
