Coprinus laniger is a small to medium-sized agaric fungus that grows in clusters on dung, rich soil, and decaying organic matter. In East and Central Texas, it typically fruits in the spring and fall, producing bell-shaped to conical caps that are 1-3 cm in diameter, with a reddish-brown to yellowish-brown color and a fuzzy or hairy appearance. The gills are free, crowded, and turn black as the spores mature. It can be found in fields, pastures, and woodland edges, often associated with cow dung or other herbivore waste.
