Antrodia madronae (Madrone antrodia)
Antrodia is a genus of fungi in the family Fomitopsidaceae. Antrodia species have fruit bodies that typically resupinate (i.e., lying flat or spread out on the growing surface), with the hymenium exposed to the outside; the edges may be turned so as to form narrow brackets. Most species are found in temperate and boreal forests, and cause brown rot.
