Description: An overlooked species usually found on the vertical faces of mossy rocks in hilly or upland areas. The thallus is dominated by squamules, grey-green above, so is easily overlooked as C. subcervicornis. Cups like those of C. pyxidata (described elsewhere). The undersides of the squamules have a distinctly radiating pink-to-yellow coloured veining. In Ireland, the species is known from Counties Down and Kerry.

Key Identification Features:

• Like a gross form of C. pyxidata but with larger basal squamules with veined undersurface, these raised and spreading from a single point
• Thallus K+ yellow; discs brown.
