Fruiting body upper surface zoned concentrically in shades of ochre, grey and rust with maroon tinge, disc-like, at first finely downy, becoming smooth with age; stem rusty-brown, downy, more or less central. Flesh brown, thin, corky, harder when dry.

Use many resources, and be skeptical of your own conclusions. Please consider that many mushrooms take years of experience to identify reliably.
