Summary

Description

Plants are erect, solitary or occur in groups. The thallus grows up to 13 mm in length and 0.25 mm wide and is thread-like in appearance. The thallus can be either straight or club-shaped and extends from a basal disc. Hairs commonly project from the thallus giving the plant its rough texture.

Recorded distribution in Britain and Ireland

A very rare species in the British Isles, only recorded from the Isles of Scilly. Due to its tiny size this species is probably under recorded.
