Description: This non-lichenised, crustose species occurs as a pale stain on heather stems, dead and worked timber, especially that of conifers. It is suggested that it is common, but it is certainly under-recorded in Ireland.

Key Identification Features:

• The pale, stain-like thallus with scattered red discs on dead wood suggests this species
• The gelatinous, convex discs (to 1mm diam.) that are a rich red to orange-brown should be examined through the microscope. The simple spores often has a central oil drop.
