Crepidotus calolepis is a small to medium-sized, fan-shaped or semicircular fungus with a wavy or lobed margin, typically 1-4 cm wide. The cap is hairy, especially when young, and ranges in color from yellowish-brown to reddish-brown. It grows on decaying wood, often on deciduous trees, and is found in East and Central Texas, particularly in wooded areas with rich soil and abundant leaf litter. In this region, it typically fruits from spring to fall, with a peak in summer months. The spore print is white to pale yellowish.
