The grey-brown thallus of this species is stretched like a skin across the lower parts of smooth-barked tree boles in wet woodlands. Hidden below and pushing up through the surface of the thallus are tiny, spherical discs (perithecia: 0.15-0.20mm diam.) with pale-pink or orange tops, fading to brown or black when older. Usually these perithecia show a wide range of colouration even within a single specimen. On trees it is most likely to overlap only with P. aenea which has shiny black perithecia. Smooth bark of trees such as ash, hazel and holly. Throughout Ireland.

Key characteristics

  • Grey to brown skin-like thallus with pink, orange, brown or blackish perithecia pushing through to the surface
