|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
Order Hymenochaetales. Hymenochaete badioferruginea and Hymenochaete
tabacina are synonyms (former names).
