AI-generated description

Crepidotus epibryus is a small to medium-sized, fan-shaped or semicircular fungus that grows on mosses, liverworts, and other non-vascular plants. It has a smooth, wavy or lobed cap that ranges in color from yellowish-brown to reddish-brown, and a white to pale yellow spore print. In East and Central Texas, Crepidotus epibryus typically fruits in the spring and fall, often on moss-covered tree trunks, rocks, and soil. The fungus is relatively common in the region's wooded areas, particularly in moist, shaded environments with abundant moss growth.
