Species Information

Summary:
Features include 1) resupinate growth on hardwood, 2) a waxy fruitbody that is pale ochraceous to pale brown, often with a grayish, reddish or violaceous tint, the surface smooth or minutely warted, and the margin indeterminately thinning out, 3) spores that are elliptic, smooth, and inamyloid, 4) 2-4-spored basidia, 5) cystidia that are cylindric and thin-walled, often containing oil droplets, sometimes with slight encrustation, 6) a monomitic hyphal system, the hyphae with at most scattered clamp connections, hyphae in the horizontal layer next to the substrate indistinct, subhymenial hyphae densely united, the tissue often filled with a fine-grainy resinous matter.

Phlebia deflectens has been found in BC, NS, and AZ, (Ginns). It has also been found in Denmark, Finland, France, Norway, Sweden, Armenia, and Azerbaijan, (Eriksson).
Fruiting body:
thin (mostly 0.01-0.02cm thick), resupinate, closely adnate [firmly attached], effused [spread out], ceraceous [waxy] when moist and alive, continuous; pale ochraceous - pale brown, often with a grayish, reddish or violaceous tint; smooth or papillose - minutely warted, "as a rule irregularly cracked when dried"; "margin indeterminately thinning out", (Eriksson)
Microscopic:
SPORES (3.5)4-5 x 2.5-3 microns, elliptic, smooth, inamyloid, acyanophilic, thin-walled; BASIDIA 2-4-spored, 25-30(40) x 3-5 microns, narrowly clavate, without basal clamp connection; CYSTIDIA "varying in number, often few", 70-120 x 4-5 microns, cylindric, thin-walled, often containing oil droplets, and sometimes with slight encrustation; HYPHAE monomitic, 2.5-3.5 microns wide, thin-walled, normally without clamp connections, but scattered clamp connections may occur in some specimens; hyphae in the horizontal layer next to the substrate "indistinct and more or less parallel", "subhymenial hyphae densely united"; "tissue often filled with a fine-grainy resinous matter", (Eriksson)

on much decayed wood, more often hardwood than conifer wood, (Eriksson), Acer saccharum (Sugar Maple), Arbutus menziesii (Pacific Madrone), Quercus sp. (oak), Quercus hypoleucoides (Silverleaf Oak), Salix sp. (willow), (Ginns)
