Species of Thelocarpon are ephemeral, but often rapid colonisers of ‘newly created’ habitat such as dumped soil, cut tree stumps, etc. The discs are extremely small and one would need to set out deliberately to find them, unless of course, one happened upon them by accident. This species will grow on burnt ground, even on discarded leather. The granules within which the discs are to be found are shiny yellow pruinose with smooth margins, spores simple 3 x 2µm. The thallus is a simple varnish-like skin. The paraphyses in the asci are long and branched. Only two Irish records are known.

Key characteristics

  • Thallus forming yellow pruinose convex granules like yellow specks with the discs (perithecia) buried within
  • Spores simple, paraphyses long, slender, branched; on burnt ground.
