Extract from Wikipedia article: Hexagonia hydnoides is a species of fungus in the Polyporaceae family. It is a plant pathogen. This fungus is largely saprophytic, decaying dead wood tissues.
Cerrena hydnoides is a crust fungus that grows on deciduous trees, particularly oak and maple. In East and Central Texas, it typically fruits in the spring and fall, producing effused-reflexed to stipitate basidiocarps with a hairy to velutinous upper surface and tooth-like hymenial surface. The fungus is commonly found on standing dead trees or stumps, often in shaded areas near streams or rivers. Its distribution in East Texas tends to be more frequent due to the region's higher rainfall and more abundant deciduous tree species, while in Central Texas it is less common but can still be found in areas with suitable habitat.
