Ossicaulis lignatilis is a species of fungus that belongs to the family Lyophyllaceae. It is a small to medium-sized mushroom with a bell-shaped to convex cap, typically 1-4 cm in diameter, and a slender stem. The cap is often yellow-brown to tan, and the gills are crowded and free from the stem. In East and Central Texas, Ossicaulis lignatilis has been found growing on decaying wood, particularly on fallen logs and stumps, in mixed hardwood forests and along streams. It tends to fruit in the spring and fall, and is considered a relatively rare species in the region.

College Station, Texas, December 4, 2018Raccoon Run, College Station, TX 77845, USAObservations of the fungus Ossicaulis lignatilis in East and Central Texas reveal that it tends to grow in hollowed-out stumps and cavities of trees. Multiple instances were found in Lick Creek Park, College Station, Texas, on different dates in October and December 2018. The fungus was observed growing inside large diameter stumps, cut tree trunks, and broad-leaved tree trunks. Specific observations include growth in a hollow stump of a cut oak tree, inside a hollowed-out stump, and in cavities of stumps and cut tree trunks. The mushrooms were found in groups and individually, with detailed observations of their gills. These findings suggest that Ossicaulis lignatilis thrives in decaying wood, particularly in protected environments such as hollows and cavities. The fungus appears to be common in the region, with multiple sightings in a relatively small area.
