Species Information
Summary:
Features include 1) resupinate growth on wood, 2) waxy fruitbodies that are cream to ocher, often with reddish, greenish or brownish areas, the surface with conic teeth up to 0.03cm long, the margin not distinct, 3) spores that are oblong, smooth, inamyloid, and colorless, 4) cystidia of 2 types: a) halocystidia, smooth with a bladder-like swelling at the tip, and b) astrocystidia, smooth and pointed with a star-like tuft of crystals, and 5) a monomitic hyphal system, the hyphae with clamp connections.
Microscopic:
SPORES 6-7.5 x 2.5-3.5 microns, irregularly elliptic, "flattened on one side and sometimes slightly curved", smooth, inamyloid, colorless; BASIDIA 4-spored, 12-23 x 5-9 microns, clavate, with basal clamp connection; CYSTIDIA of 2 types 1) halocystidia smooth with bladder-like swelling at tip, 2) cystidioles smooth and pointed with star-like tuft of crystals; HYPHAE monomitic, 1.5-4 microns wide, with clamp connections, (Breitenbach), SPORES 5.5-8 x 2.5-3.5 microns, oblong, adaxial side straight or slightly convex, smooth, inamyloid, acyanophilic, thin-walled, usually without oil droplets; BASIDIA 4-spored, when young clavate, 15-25 x 4-6 microns, with basal clamp connection; CYSTIDIA of 2 types, both as a rule numerous: 1) halocystidia which are capitate, with a distal, thin-walled bladder, 10-20 microns wide, that contains "resinous or oily grains or drops", and 2) astrocystidia, from hyphal ends narrowing into a peg, bearing a star-like cluster (about 10 microns across) of radially arranged crystals; HYPHAE monomitic, 2-3 microns wide, thin-walled, fairly densely septate and with clamp connections at all septa; in the center of the teeth packed in parallel fashion, "joined by anastomoses, and continuing into the apical tuft of sterile hyphae"; "hyphae of the thin subiculum densely branched and intertwined", (Eriksson)

on rotten barkless conifer wood, more rarely also on wood of hardwoods, (Breitenbach), on barked or more common barkless wood, causing an intense white decay; common on slash in lumbered forests, (Eriksson), on a variety of conifers and hardwoods; causes a root and butt rot in Abies amabilis (Pacific Silver Fir) and Thuja plicata (Western Red-cedar), root rot in Abies lasiocarpa (Subalpine Fir) and Abies balsamea (Balsam Fir), and trunk rot in Abies balsamea and young Abies grandis (Grand Fir), (Ginns), all year; including worked timber, (Buczacki)
