Oxyporus populinus

The Mossy Maple Polypore
gets its name because it often has moss
growing on it. It is a shelf mushroom
which grows on the trunks of maples and other
deciduous
(loses leaves in Fall) trees. The cap
of this mushroom grows up to eight inches wide and can be
several inches thick. Mossy Maple Polypore
flesh is white and very tough, and its caps often overlap
each other. These fungi do not have stalks. Mossy Maple Polypore can
be found year-round. It is usually seen near the base of a
tree trunk,
especially where the tree is wounded. If you touch this fungi,
it should feel hairy. Part of the reason the
flesh is so tough is because these mushrooms add a new thick
layer each season. This mushroom is
considered a parasite,
since it grows on tree wounds and takes nutrients
away from the tree. It is used as a food
source by insects such as Fungus Gnats and Horned Fungus
Beetles.

Insects also help this fungus spread. When Fungus Gnats or beetles move in and out of the mushroom, spores (like seeds on a plant) stick on the insect's body. Then, when the insect moves on, so do the spores, to a new place where a new mushroom may grow.

Relationsip to Humans:
Mossy Maple Polypores are not eaten by people. They help speed up the dying process for sick trees and weaken wood for cavity-dwelling creatures. They can also damage wood that was to be used as lumber.
