Hypoxylon Oak Canker (Biscogniauxia atropunctata)
Growing on a standing red oak tree at the top of a ridge in a dense mixed hardwood coniferous forest. A handful of oaks are infected in our area as we had a terrible drought back in 2016.
Hypoxylon Oak Canker a.k.a. "Biscogniauxia Dieback" is a white-rot fungus that infects primarily Oak (Quercus sp.) trees, usually following a period of stress like a drought. The fungus will eventually cut off the supply of water and nutrients to the tree by destroying the sapwood (nutrient-conducting tissues).
A species of fungus within the Xylariaceae family.
