This image depicts a close-up view of a rotten tree stump covered with brown polypore mushrooms identified as Brunneoporus malicola.
The stump appears to be made of light brown wood and has several cracks running vertically across it. The surface is covered with numerous small, irregularly shaped growths that are tan or light brown in color. They have rounded edges and are clustered together in a random pattern.
They appear to grow in different directions on the stump and some seem to overlap each other.
The overall texture of the image suggests that the mushrooms are growing directly from the rotting wood, with no visible substrate or soil present. – AI vision
