Description: This is a species of broadleaved trees. The thallus is granular-warted and the clustered discs, dark red-brown. It appears to agree microscopically with S. moriformis (described elsewhere) in the simple, spherical spores, 1.5–2.5µm. There is some speculation that S. pinicola may be just an ecotype of that species. It appears to be tolerant of mild air pollution, so should be searched for in the parks of Belfast and Dublin.

Key Identification Features:

• Thallus grey-brown, granular with tiny red-brown clustered discs
• Spores globose, simple, on wayside or parkland trees; it is not a woodland species.
