Postia ptychogaster, commonly known as the powderpuff bracket, is a species of
fungus in the family
Fomitopsidaceae. The fungus, which is found in Europe, resembles a powdery cushion that fruits on stumps and logs of rotting
conifer wood. In this stage of its
life cycle, the "cushion" is a mass of
chlamydospores.[1]
