Tomentellopsis echinospora is a species of fungus in the family Thelephoraceae. It produces resupinate to reflexed, waxy to velvety basidiocarps with a white to cream-colored surface and a smooth to tuberculate hymenium. In East and Central Texas, it has been found growing on decaying logs, stumps, and other woody debris in mixed hardwood forests, particularly in areas with rich soil and abundant moisture. Fruitings typically occur from spring to fall, with peak activity during the summer months. Microscopic characteristics include ellipsoid to subglobose basidiospores measuring 6-9 μm in length, which are echinulate with short spines.
