Sarcodontia unicolor is a species of tooth fungus that grows on deciduous trees, particularly oak and maple. In East and Central Texas, it typically fruits in late summer to early fall, producing small to medium-sized, semicircular to kidney-shaped caps with a wavy margin, ranging in color from pale yellowish-brown to dark brown. The spines or teeth on the underside of the cap are decurrent, white to cream-colored, and 1-3 mm long. It can be found growing singly or in small groups on logs, stumps, and fallen branches, often in shaded, moist areas near streams or rivers.

Cross section of wood decay fungus Spongipellis unicolor (Tyromyces unicolor, Polyporus obtusus, Sarcodontia unicolor)(?) on Lone Star Hiking Trail near Pole Creek in Sam Houston National Forest. Richards, Texas, August 5, 2020Lone Star Hiking Trail, Montgomery, TX 77356, USAObservations of the fungus Sarcodontia unicolor in East and Central Texas reveal its presence on a fallen oak at the base of a tree on the Lone Star Hiking Trail near Pole Creek in Sam Houston National Forest. The fungus was found to have large pores on its underside, with a unique cross-section structure. The observations were made on August 5, 2020, in Richards, Texas. The fungus was identified as Spongipellis unicolor, also known by other names such as Tyromyces unicolor, Polyporus obtusus, and Sarcodontia unicolor. The specimens were found to be decayed wood, suggesting that the fungus plays a role in breaking down organic matter in the forest ecosystem. The large pores and cross-section structure of the fungus provide insight into its morphology and potential functions. Further study is needed to fully understand the characteristics and behaviors of Sarcodontia unicolor.
