Irpicodon pendulus is a species of fungus that belongs to the family Amylocorticiaceae. It is characterized by its pendulous, bracket-like or tooth-like fruiting bodies that are typically 1-5 cm long and 0.5-2 cm wide. The fungus grows on deciduous trees, particularly oak and elm, in East and Central Texas, often forming clusters on the trunks or branches. Its cap is usually grayish-brown to brown, with a smooth to wrinkled surface, and its spines or teeth are white to cream-colored. In Texas, Irpicodon pendulus typically fruits from spring to fall, with peak activity during the summer months.
