Agaricus brunneofibrillosus, commonly known as the dusky mushroom or bleeding agaricus, is a species of fungus in the family Agaricaceae. It has a medium to dark brown cap up to 6 cm in diameter with brownish fibrillose scales that darken in age. The tightly packed gills are initially cream colored before becoming pinkish, lilac-gray, and finally brownish as the spores mature. The stout stem is enlarged to bulbous at the base, which has one or more brown bands, and a white, membranous ring.
