About

Mar 15, 2018

When we found this mushroom we had no idea why it was covered with these tiny disgusting holes and bumps. Later we found out this is a gall created by eggs laid by Agathomyia wankowiczii, the yellow flat-footed fly. The fly is the only insect which creates a gall on fungus, and only ever on one species of fungus, Ganoderma applanatumThe grubs hatch and fall to the ground out of the little holes. Also it looks horrifying.
