Gloeophyllum carbonarium is a brown-rot fungus that decomposes cellulose and hemicellulose in wood. In East and Central Texas, it has been found growing on dead trees, stumps, and fallen logs, particularly on oak and pine species. The fungus produces fruiting bodies that are semicircular to bracket-shaped, 2-8 cm wide, and 0.5-2 cm thick, with a crusty upper surface and a yellowish-brown to dark brown color. It is relatively common in the region, especially in areas with abundant hardwoods and conifers.

AI-generated summary of observations
The fungus Gloeophyllum carbonarium was observed in East and Central Texas, specifically in the Sam Houston National Forest. The observations span from January 2022 to January 2024. The fungus was found growing on burned pine logs, stumps, and fallen trees, often forming small colonies or spreading patches. Close-up images revealed the texture and brown pores of the fungus. Some observations noted the presence of other fungi, such as a white corticioid fungus, growing alongside Gloeophyllum carbonarium. The majority of observations were made on the Richards Loop Trail, with a few on the Lone Star hiking trail. The consistent presence of the fungus on burned pine substrates suggests a preference for this environment. Overall, the observations provide a detailed record of the fungus's growth and distribution in the region.
