Rusty Gilled Polypore

This rusty gilled polypore is under the squirrel tree. 

Gloeophyllum sepiarium, the rusty gilled polypore, is a wood decay fungus that causes a brown rot. It grows in thin, dark brown brackets on dead trees. The fruiting body grows for only one year, and produces spores in late summer and autumn.  The rusty-gilled polypore is extremely common across North America. The gills are evident on the underside.

This one is by the trail, found earlier.

Saprobic on the deadwood of conifers.

Common name: Conifer Mazegill
