Hymenochaete rubiginosa
This fungus spreads and forms caps (effused-reflexed) on old logs and stumps,
growing and producing spores for several years.  Caps develop concentric zones
of color and become very hard, breaking like a thin seashell.  The fertile (spore
producing) surface is orange-brown and covered with tiny, bristle-like spines

(setae)
. Previously misidentified here as Pseudochaete tabacina.

Order Hymenochaetales.
