Yellow Toothcrust

Sarcodontia uda forms resupinate fruiting bodies that spread across wood surfaces. The fertile surface is yellow to orange-yellow and develops tooth-like or spiny projections with age. The fungus has a soft to somewhat waxy texture when fresh.

It grows on decaying hardwood, especially old fruit trees such as apple and pear, where it causes wood decay.

Sarcodontia uda is a saprotrophic fungus that decomposes dead or weakened wood. It is associated with white rot in hardwood trees.

The genus name Sarcodontia refers to the fleshy tooth-like structures of the fungus, while the specific epithet uda originates from the original species description by Elias Magnus Fries.
