The underside does not have visible pores. Amylostereum areolatum, on conifer wood, is similar but has zoned cap that often is moss-covered. Chondrostereum purpureum typically produces thin but tough brackets with finely hairy caps. These are whitish at first, becoming weakly zoned in shades of gray to purple-brown, the margins undulate and whitish. The undersides are smooth though rather knobbly, and are purple to purple-brown, growing over the wood below the caps, and often coalescing with other fruitbodies.
