Description: This scarce species first described from Irish material in 1980, is found on the dry, sheltered bases of old trees in oceanic woodland valleys. It grows initially on dry bark lichens such as Lecanactis and Enterographa until later becoming independent. The thallus is a pale pinkish-white and cottony textured web-like (not crustose). In Ireland, the species occurs on holly (Kerry) and oak (Waterford).

Key Identification Features:

• Initially lichenicolous on dry bark lichens (for example, Lecanactis abietina)
• Later becoming an independent crust.
