Peniophora cinerea is a crust-like fungus that grows on dead wood, typically on deciduous trees. In East and Central Texas, it has been found on various substrates, including oak, elm, and cedar. The fungus produces small, grayish-brown to pale brown fruiting bodies with a wavy or lobed margin, and its spores are cylindrical to ellipsoid in shape. It is commonly encountered in wooded areas, particularly in the spring and fall months when moisture levels are higher.
Observations of the fungus Peniophora cinerea in East and Central Texas revealed its presence on dry stems of Yaupon holly in Little Thicket Nature Sanctuary, Cleveland, Texas. The fungus was found growing alone and together with Hypoxylon, a black corticioid fungus. It formed a crust-like pattern on the stem, with basidia and spores visible under closer examination. The basidia were observed to be intact, while the spores were also present, indicating active growth and reproduction of the fungus. Multiple observations on March 23, 2024, confirmed the consistent presence and characteristics of Peniophora cinerea on Yaupon holly in this region, suggesting a possible symbiotic relationship between the fungus and its host plant. The findings provide insight into the ecology and distribution of this corticioid fungus in East and Central Texas.
