Species Information
Summary:
Physisporinus sanguinolentus forms a whitish pore surface with pores 8-10 per mm (growing flat on wood) that quickly shows rusty blotches after collecting or bruising. According to Ginns(28), the fruitbodies shrink significantly and discolor on drying to gray or black, the color change distinguishing this species from other polypores in BC that grow flat on wood.
Odor:
weak (Breitenbach)
Taste:
mild (Gilbertson, Breitenbach)
Microscopic:
spores 5-6 x 4-4.5 microns, oval to nearly round, smooth, inamyloid, colorless; basidia 4-spored, 12-14 x 6.5-8 microns, broadly clavate, simple-septate at base; cystidia none, "fusoid cystidioles present, 15-19 x 5-6 microns, simple-septate at the base"; hyphae monomitic, hyphae of subiculum 3.5-6.5 microns wide, colorless in KOH, thick-walled to thin-walled, rarely branched, simple-septate, hyphae of trama 2-4 microns wide, similar, (Gilbertson), spores 5-6 microns in diameter, nearly round, smooth, inamyloid, colorless, with droplets; cystidioles inconspicuous, in the hymenium 12-25 x 5-7 microns, fusiform, smooth; "in addition occasional cystidialike hyphal ends with incrusted tips", 3-5 microns wide, thin-walled, (Breitenbach)
Spore Deposit:
white (Buczacki)
Notes:
Physisporinus sanguinolentus has been found in BC, WA, OR, ID, ON, AK, AZ, CA, FL, LA, MN, MT, NM, NY, and PA, (Gilbertson).
Habitat and Range
SIMILAR SPECIES
Physisporinus vitreus has a distinct bluish white semitransparent color, changes only slowly pale brown (or not at all) when bruised, and has larger pores, (Gilbertson). Physisporinus rivulosus has pores 3-4 per mm and clamp connections: it bruises rusty red to brown but the discoloration is faint, (Ginns). Dried fruitbodies of Rigidoporus crocatus "are sometimes similar but are much harder and not white to ivory when fresh and usually retain their pinkish coloration after drying", (Gilbertson).Habitat
annual, or reviving a second year, on dead wood of conifers and hardwoods, causing a white rot, (Gilbertson), on moist dead wood of hardwoods and conifers, "commonly on stumps and then often growing over surrounding plant remains and soil", (Breitenbach), summer to fall (Buczacki)
