Habitat / Range
annual, most common on Salix (willow) and Populus, also reported on Betula (birch) and Abies (fir), associated with white heartrot of living hardwoods and also on stumps, (Gilbertson), single or imbricate [shingled], often concrescent, on "old, dead or still living trunks and branches of Salix (willow)", (Breitenbach)
Haploporus odorus similar macroscopically and has anise odor, but slightly darker in color, grows only on Salix (rarely Fraxinus), has a restricted range, and microscopically spores are smaller and finely spiny, (Gilbertson); Haploporus odorus (Sommerf.) Bondarzev & Singer is a synonym according to some authors, including the online Index Fungorum (accessed Oct. 20, 2004)
