Pleurotus ostreatus is a widely distributed edible fungus that grows on trees, stumps, and other decaying wood. In East and Central Texas, it typically fruits from spring to fall, often in shaded, humid areas near water sources. It can be found on various tree species, including oak, elm, and willow, with caps ranging from 1-4 inches in diameter, fan-shaped or oyster-shaped, and grayish-brown to tan in color. The gills are decurrent, and the stem is short or absent. In Texas, it is commonly found in urban and rural areas, including parks, woodlands, and along rivers and streams.
