    Can anyone ID this fungus?

    Does anyone know what fungus this is? It was found on a Laurel Oak in Central Florida. The fungus gives off small clouds of spores when touched. I have seen a similar fungus before on an oak, but in its later stages. The fungus I believe turns black and hard. It appears to attack the vascular system of the tree, ultimatley removing the bark and killing the tree. Both tree were located in waterlogged or over watered areas.
    I do not know the answer to this question so any feedback would be welcomed. Thanks

    Look into Hypoxylon mammatum. Page 346 in Shigos 'A New Tree Biology'.

    Called Ustulina deusta in Europe, according to Schwarze. Trees can compartmentalize it sometimes, though it's often a harbinger of death. Weird thing about it is it's carried inside the tree until the tree is strained, then it grows.
