Sulphur Disco

Sulphur Disco - Calycina claroflava

Alternative names
Bisporella sulfurina
Description

Small brightly coloured yellow discs or shallow cups growing on dead wood, found in association with a dead pyrenomycetous fungus such as a barkspot or woodwart (e.g. Diatrype, Diatrypella or Hypoxylon).  More brightly coloured and slightly smaller  than more common Lemon Disco, Bisporella citrina, but separating the species with certainty requires measurement of spore size or demonstrating the close association with the pyrenomycete.
