Species Information
Summary: Features include 1) resupinate growth on barkless conifer wood, 2) a somewhat gelatinous whitish to watery gray or livid fruitbody, the margin usually thinning out but often distinct, 3) spores that are suballantoid, smooth, and inamyloid, 4) basidia often with a gelatinous cover and also somewhat thick-walled, 5) cystidia that are awl-shaped, sometimes with septa, 6) a monomitic hyphal system, the hyphae embedded in a gelatinous matrix, with clamp connections, and 7) subiculum lacking or thin.
Phlebia segregata has been found in BC, MB, ON, PQ, and LA, (Ginns), as well as Finland, Norway, and Sweden, (Eriksson).
Fruiting body: mostly 0.01-0.02cm thick, resupinate, adnate [firmly attached], somewhat gelatinous, firm, membranaceous to corneous [horny] when dried; whitish then watery grayish or livid, when wet somewhat translucent, "in the herbarium often yellowish, pale ochraceous or sordid, the projecting cystidia causing a change to whitish when looked at from the side"; margin usually thinning out but often quite distinct, (Eriksson), slimy to gelatinous; spore deposit white (Buczacki)
Microscopic: SPORES 5-7 x 2-2.5 microns, suballantoid, smooth, inamyloid, acyanophilic, thin-walled; BASIDIA 4-spored (normally), 15-25 x 4-5 microns, narrowly clavate, "often with a gelatinous cover and also somewhat thick-walled", with basal clamp connection; CYSTIDIA numerous, 50-70 x 6-10 microns, subulate-acute [awl-shaped], a few obtuse, "walls at first thin then thickened, sometimes with adventitious septa"; HYPHAE monomitic: hyphae 2-3 microns wide, embedded in gelatinous matrix, thin-walled, with clamp connections, subiculum lacking or present as thin horizontal layer, (Eriksson)
Habitat / Range
mostly on conifer wood (rarely on hardwood), generally on barkless wood, also on timber, (Eriksson), Picea sp. (spruce), Pseudotsuga menziesii (Douglas-fir), Tsuga heterophylla (Western Hemlock), (Ginns), late summer, fall, winter, spring, (Buczacki)
