Showing Hypoxylon thouarsianum, a sapwood decay fungus that is also commonly isolated from Sudden Oak Death - affected oak trees, although it is also found on trees not affected by SOD. The presence of the half-dome-shaped fruiting bodies are indicative of advanced stages of SOD. Newly formed fruiting bodies are olive greenish or shiny black and release powdery green spores upon contact. Older fruiting bodies are dull black. |
