Postia ptychogaster

Powderpuff bracket

The asexual stage of the fungus Ptychogaster albus produces hemispherical to vesicular fruiting bodies 4 cm wide, soft, coarsely bushy, first white, later pink and brownish, sometimes fragrant drops of water. In old age it breaks down into brown dust (chalmydospores) as powders. Under suitable conditions, the fungus produces sexual fruiting bodies with tubes. They are spilled to cap, growing from July to November. Hat 1 - 4 cm wide, irregularly semicircular, freshly fleshy, covered with pressed hairs, white. The pores are white, later cream. Mycelium causes brown rot.
