Extract from Wikipedia article: 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.
Postia ptychogaster is a species of fungus in the family Fomitopsidaceae. In St. Petersburg and Leningrad Oblast, it has been found growing on coniferous trees, particularly spruce and pine. In north-western Russia, it is widely distributed and commonly occurs in boreal forests, often associated with dead or decaying wood. The fungus produces annual to biennial fruiting bodies that are resupinate to effused-reflexed, with a smooth to wrinkled hymenium and ellipsoid to cylindrical spores.
