Yellow pitted rot
Western North America
Damage, symptoms and biology
The presence of a fruiting body indicates extensive decay in the stem. Hericium abietis has been reported to reduce merchantable volume by up to 3.1% in amabilis fir.
The fruiting bodies are generally found on slash and on the ends of cut logs but they may also form on wounds on living trees. Because of their fleshy nature, they are short lived.
