The image shows a close-up of a tree trunk with a large, yellow mushroom growing on it. The tree trunk is weathered and has a rough texture, with patches of bark visible. The mushroom has a round, oval-shaped cap with a slightly wrinkled texture. It is growing on the bark of the tree and is surrounded by green grass and small plants. The background is blurred, but it appears to be a grassy area with more trees and shrubs.
