An uncommon Inocybe with prickly-scaly reddish-brown cap and fibrous stem of same colour. Sometimes both cap and stem may be scaly. The main characteristic is the subglobose to rather elongate spores with blunt-tipped spines. A category of Inocybe has spores with blunt nodules, but these spores are definitely spiny. Another feature is the presence of 4- and 2-spored basidia on the gills. 1st Notts record.
