Bisporella citrina – minute lemon cup, yellow fairy cups
Description: Bisporella citrina is perhaps the most noticeable of the inoperculate discomycetes, as it is very common, bright yellow, and fruits in large numbers on hardwood branches that have lost their bark. Although there are other small, yellow, cushion-like discomycetes, none of them are as common or fruit in such abundance.
Substrate: Hardwood branches
