Arthonia fuscopurpurea (Tul.) R.Sant.

Lacks a thallus or its own photobiont (and arguably a "lichen" only as a member of a generally lichenised genus), occurs in the thallus of Peltigera hymenina, forming rounded, red-brown to blackish, flat to convex apothecia. Scattered records in the north and west, no doubt under-recorded but not common. Refs: Smith et al. (2009), 162; Purvis et al. (1992), 81.

 

In thallus of Peltigera hymenina, Taynish, Argyllshire, May 2011, det. Brian Coppins (material lent by Les & Sue Knight).
