Hohenbuehelia angustata is a species of fungus that belongs to the family Pleurotaceae. It is a small to medium-sized mushroom with a fan-shaped or semicircular cap, typically 1-4 cm wide, and a wavy or lobed margin. The cap surface is smooth, often with a wrinkled or veined appearance, and ranges in color from grayish-brown to dark brown. The gills are crowded, narrow, and decurrent, with a similar color to the cap. The stem is short, stout, and often lateral or off-center. In East and Central Texas, Hohenbuehelia angustata has been found growing on decaying wood, particularly hardwoods like oak and elm, in moist environments such as streams, rivers, and woodland edges. It typically fruits in the spring and fall, and is considered a relatively rare species in the region.
