About Pseudosperma sororium (Kauffman) Matheny & Esteve-Rav.
The cap of Pseudosperma sororium measures 3.5 to 11 centimeters in diameter. It starts out conical in shape and becomes umbonate as it ages. The cap is yellowish brown or straw-colored, with a heavily fibrillose texture. Older caps begin to split, and at this stage they can resemble straw. The stipe is 6 to 12 centimeters long, 1 to 2 centimeters wide, has a slightly wider base, and bears a cortina. The gills are pale when young, darken to brownish as the mushroom ages, and can be sinuate, adnexed, adnate, or free. The spore print of this species is brownish, and the mushroom has a scent similar to green corn. Pseudosperma sororium grows in forests, found under both hardwood trees and conifers. It produces fruiting bodies during fall and winter. This mushroom is poisonous, and contains the toxin muscarine.
