Extract from Wikipedia article: Ganoderma lobatum is a plant pathogen.
Ganoderma lobatum is a perennial, bracket-like fungus that grows on living trees, particularly oak and pine. In East and Central Texas, it is commonly found on mature trees, especially those stressed by drought, disease, or injury. The fungus produces large, woody, kidney-shaped conks with a glossy, brown to black cap and white to yellow pores underneath. It causes heart rot and can lead to significant structural decay in infected trees.

Spores of bracket polypore mushrooms Ganoderma lobatum collected 4 days before on Caney Creek Trail (Little Lake Creek Loop Trail) in Sam Houston National Forest north from Montgomery. Texas, September 29, 2022
Spore size 7.6 - 9 × 4.3 - 4.7 µm, length to width ratio Q = 1.8 - 2.Observations of the fungus Ganoderma lobatum in East and Central Texas reveal its presence on various substrates, including living trees, stumps, and rotten wood. The fungus was found at multiple locations, such as Lick Creek Park in College Station, Sam Houston National Forest near Huntsville, and Big Creek Scenic Area. It grew in different forms, including brown vase-shaped mushrooms and polypore bracket fungi, often at the base of oak trees. The pore surface of the fungus was observed to be characteristic of the species. Cross sections of the mushroom revealed its internal structure. Spores of the fungus were also collected and examined, showing contamination by spores of other species in some cases. Overall, Ganoderma lobatum appears to be widespread in East and Central Texas, growing on a variety of substrates and in different environments.
