Common name: white-rot fungus.
Punctularia strigosozonata is a species of crust fungus that grows on dead logs and stumps. In East and Central Texas, it typically fruits in the spring and fall, producing resupinate to effused-reflexed basidiocarps with a hairy, zonate upper surface and a smooth, poroid lower surface. The fungus is often found on deciduous substrates, particularly oak and elm, in shaded, humid environments such as riverbanks and woodland edges. Its distribution in the region appears to be widespread but sporadic, with records from several counties including Brazos, Grimes, and Travis.

Resupinate mushrooms Punctularia strigosozonata with their underside on a fallen oak on Sand Branch Loop Trail in Sam Houston National Forest near Montgomery. Texas, June 22, 2021The fungus Punctularia strigosozonata was observed in East and Central Texas from August 2020 to June 2021. The observations were made in Sam Houston National Forest and Lick Creek Park, where the fungus grew on fallen oaks. The mushrooms were resupinate, with velvety caps and a merulioid texture on their lower surface. They were found in various stages of development, from young to mature, and some exhibited guttation (exuding water drops). The fungus was often found in large masses, covering significant areas of the fallen trees. The observations suggest that Punctularia strigosozonata is a common species in the region, thriving on decaying oak wood. The consistent presence of the fungus across different locations and times suggests its adaptability to the local environment. Overall, the observations provide valuable insights into the growth habits and distribution of this fungus species.
