Extract from Wikipedia article: Phellinus gilvus is a plant pathogen which infects several hosts.
Phellinus gilvus is a perennial, bracket-like fungus that grows on deciduous trees, particularly oak and elm. In East and Central Texas, it typically fruits in the spring and fall, producing semicircular to fan-shaped caps with a yellowish-brown to grayish-brown upper surface and a white to yellowish pore surface. The fungus is commonly found on living trees, stumps, and logs, causing a white rot that can lead to significant decay. It is widely distributed in the region, often occurring in urban and rural areas with abundant hardwood vegetation.

Spores of mustard yellow polypore mushrooms (Phellinus gilvus) collected 2 days before on Sand Branch Loop Trail in Sam Houston National Forest near Richards. Texas, February 17, 2024The observations document the presence of Mustard Yellow Polypore mushrooms (Phellinus gilvus) in various locations across Texas, primarily in Sam Houston National Forest and surrounding areas. The fungus was found on multiple tree species, including oak, hardwood, and sweetgum, often on fallen logs or at the base of trees. Observations were made over several years, from 2022 to 2024, with frequent sightings on specific trails such as Caney Creek section of Lone Star Hiking Trail and Sand Branch Loop Trail. The mushrooms were described in various stages, including caps, undersides, and spores, which were also examined under a microscope. The consistent presence of Phellinus gilvus in these areas suggests it is a common species in the region, thriving on decaying wood and playing a role in the local ecosystem.
