Bisporella sulfurina


    Fresh fruit bodies are stalkless, bright yellow cups, with paler margins and exteriors. As they age, they become paler yellow or almost white.  they reach up to 1 mm in diameter.

    Identification difficulty

    They grow on old stromata of pyrenomycete fungi, especially those of the genera Diatrype, Diatrypella and Hypoxylon, which have, in turn, fruited on decaying wood from deciduous trees.  They grow gregariously on their host and often two or three will be seen tightly clustered together.

    When to see it
