Trichia scabra is a species of slime mold characterized by its small to medium size, typically 0.5-2.0 mm in diameter, with a dull yellow to orange-brown color and a rough, wart-like appearance on its sporangium. In East and Central Texas, it is often found on decayed logs, stumps, and other woody debris, particularly in moist, shaded areas. It tends to thrive in environments with rich organic matter and moderate to high humidity, such as wooded streams, ravines, and forest edges. The species is relatively common in the region, fruiting from spring to fall, with peak activity typically occurring during the late summer months.

On December 27, 2019, Trichia scabra was found on a fallen oak along Caney Creek Trail in Sam Houston National Forest, north of Montgomery, Texas. The slime mold formed a distinctive texture, with a rough, scabrous appearance. Close-up observations showed the intricate details of the species' morphology. The habitat of the fallen oak provided a suitable environment for Trichia scabra to thrive, likely due to the presence of moisture and organic matter. The observation highlights the species' ability to colonize and decompose decaying wood in East and Central Texas ecosystems. Further study could provide insight into the ecological role of Trichia scabra in these regions. The species' texture and morphology were well-documented through photographs taken during the observation.
