Pycnothelia papillaria Dufour
Primary thallus granular, supporting short, vertical, cylindrical, simple or branched podetia topped by brown pycnidia; apothecia red-brown, clusted on the podetial tips, but rare. On peat, locally throughout Britain where suitable habitat exists but inevitably absent from most of lowland England and southern Scotland. Easily taken to be a Cladonia, in which genus it was formerly included.
