Irpex subrawakensis is a species of fungus in the family Meruliaceae. It is a small to medium-sized, resupinate fungus that grows on deciduous logs and branches. In East and Central Texas, it has been found on a variety of substrates, including oak, elm, and willow. The fungus produces white to cream-colored, wavy or irregularly shaped brackets with a smooth to velvety texture. Its spores are cylindrical to allantoid in shape and measure 4-6 μm in length. Irpex subrawakensis is relatively rare in the region, but can be found in moist, wooded areas during the spring and fall months.

Spores of hydnoid mushroom Irpex subrawakensis (Steccherinum subrawakense)(?) collected a day before on South Wilderness Loop Trail at Little Lake Creek Wilderness in Sam Houston National Forest near Richards. Texas, April 4, 2024Observations of the fungus Irpex subrawakensis in East and Central Texas reveal its growth habits and characteristics. The fungus was found growing on fallen oak branches in Lick Creek Park, College Station, and in Sam Houston National Forest near Montgomery. It typically grows in a tooth-like or hydnoid pattern, with spiny underside surfaces. The caps of the mushroom were observed to be broken or intact, and the spores were collected for further study. In different locations, such as Sand Branch Loop Trail and South Wilderness Loop Trail, the fungus was found growing on fallen hardwood branches, often alongside other species like E. caryae. The observations spanned several months, from January 2020 to April 2024, indicating that Irpex subrawakensis is present in the region throughout the year. The spores collected during these observations were likely used for identification and further research purposes.
