Common name: blushing crust.
Heteroradulum deglubens is a species of tooth fungus that grows on decaying wood, particularly hardwoods. In East and Central Texas, it has been found on submerged logs and branches in freshwater habitats, such as rivers and streams. The fungus produces small, spine-like structures and has a gelatinous to rubbery texture when fresh, becoming leathery and brown when dry. It is relatively rare in the region, but can be encountered in areas with abundant woody debris and moist environments.
