General Description:

Fomitopsis ochracea Stokland & Ryvarden was described only 4 years ago, based on specimens collected on Populus tremuloides in Alberta. The type specimen and other specimens collected at the same time all had fairly large perennial basidiocarps, so that initially it was a bit difficult to believe that nobody had noted it before. In an attempt to ensure that the species had not been described earlier under a name that had gone unnoticed, specimens were circulated to some North American mycologists well acquainted with the wood inhabiting species on their continent. It turned out that until then this species had avoided detection by masquerading under a false name.
The second report of the species occurred a year ago, when Andrus Voitk reported in OMPHALINA finding the species on Betula papyrifera and B. alleghaniensis in Newfoundland, extending the distribution and host ranges. I have examined those specimens and confirmed them to be Fomitopsis ochracea. Since all hosts documented so far were deciduous trees, and since Andrus was not aware of seeing the same species on conifers, for a while we believed it to be a species limited to hardwood (Leif Ryvarden, 2012, Omphalina, “Is Fomitopsis ochracea endemic in Canada?”; Vol. III, No 3.).
