Phlebia tremellosa is a species of fungus that belongs to the family Meruliaceae. It is characterized by its gelatinous to leathery fruiting body, typically 2-10 cm in diameter, with a wavy to lobed margin and a yellowish-brown to reddish-brown upper surface. In East and Central Texas, Phlebia tremellosa has been found growing on deciduous trees, particularly oak and maple, often on dead or dying branches and trunks. It fruits from spring to fall, with peak activity during the summer months. The fungus is relatively common in the region's forests and woodlands, where it plays a role in decomposing organic matter and recycling nutrients.
