Gloeophyllum sepiarium
Gloeophyllum sepiarium (Rusty gilled polypore) 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.

Description
The cap is 1.5–15 centimetres (1⁄2–6 in) wide, loosely fan-shaped, brown with a yellow-orange margin during growth, velvety then smooth, and leathery with a mild odor and taste. The tissue darkens in KOH. The flesh is tannish. The gills are adnate and close, light when fresh and darker both near the wood and in age. The spores are white, cylindrical, and smooth. The spore print is white. 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. The species is inedible.
