Rusty-Gilled Polypore (Gloeophyllum sepiarium)

"Gloeophyllum sepiarium" is a wood decay fungus that causes a brown rot. "Gloeophyllum sepiarium" grows in thin, dark brown/green brackets on dead conifers. Often found on wood in lumberyards, the fruiting body grows for only one year, and produces spores in late summer and autumn. Its hymenial surface is distinctive from other polypores due to the presence of gills. "Gloeophyllum sepiarium" is inedible.
