Hyphodontia barba-jovis is a crust fungus that grows on dead wood, characterized by its effused-reflexed to pileate basidiocarps, white to cream-colored pore surface, and subglobose to broadly ellipsoid spores. In East and Central Texas, it has been found on various deciduous trees, including oak, elm, and willow, typically in moist environments such as riverbanks and floodplains. The fungus is relatively common in the region, fruiting throughout the year, with a peak in spring and fall.

Spores (under applied pressure) of hydnoid mushroom Hyphodontia barba-jovis(?) (second sample) collected 2 days before near Caney Creek in Sam Houston National Forest. Texas, January 2, 2023Observations of the fungus Hyphodontia barba-jovis in East and Central Texas reveal that it can be found on hardwood logs. In Sam Houston National Forest, spores of the yellowish-brown tooth fungus were collected from a log near Caney Creek. The fungus was observed to produce spores when collected 2 days prior to observation. A second sample collected from the same area also produced spores, which were released under applied pressure. The presence of Hyphodontia barba-jovis on hardwood logs in this region suggests that it may be a common inhabitant of decaying wood in East and Central Texas. The observations were made in January 2023, indicating that the fungus may be active during the winter months in this region. Further study is needed to confirm the identity of the fungus and its distribution.
