Phaeocalicium polyporaeum is a fungus in the family Mycocaliciaceae that parasitizes certain species of bracket fungi, particularly those in the genus Trametes. In East and Central Texas, it has been found growing on the fruiting bodies of Trametes versicolor and other polypores, typically appearing as small, dark brown to black stalked apothecia with a rounded to oval cap. The fungus is relatively rare in the region, but can be found on decaying logs and stumps in wooded areas, particularly during the spring and fall months when host fungi are most active.
