John i have a couple of samples on fomitopsis pini-canadensis with the black hairs. The infected pore area is yellowed.

useful paper

Very cool. Here is my thought. At first glance one may consider Hypomyces auriantius because it is orangish and on a polypore. Thing that are more specific to the host Fomes fomentarius would include Sporophagomyces but I have never seen it orange and its shape is distinctive, the color of it would be whitish, yellowish or pinkish. And both of those do not have the black hairs. Things that look like black hairs that grow on polypores would be Ascocodinaea polyporicola. We need to do some host checking. I know it has been reported Trichaptum and Trametes versicolor. The black hair like structures are really the conidiophores. Also only the anamorph stage gets the hairs. Ok really wish you had a specimen so i could scope it. What else can get black hairs on polypores. Ascocodinaea stericola but still have a possiable host problem it has been reported on Stereum. Its anamorph is Codinaea sp. and is black to gray black hair like but in this state you will not see any perithecia.
