Species Information
Summary: Features include 1) resupinate growth on conifer wood, 2) fruitbodies that are thin at first but become thicker and waxy, the color whitish to cream, the surface smooth or merulioid, and the margin white, 3) spores that are small, nearly round, smooth, inamyloid, and colorless, 4) hyphal cystidia present or not, when present projecting, usually septate and with clamp connections, and 5) a monomitic hyphal system, the hyphae with clamp connections, the subhymenial hyphae usually with crystalline deposits.
Ceraceomyces sublaevis has been found in BC, WA, ON, PE, PQ, CO, CT, NC, NH, NY, OH, PA, RI, and TN, (Ginns), and Austria, Czechoslovakia, Estonia Finland, France, Germany, Netherlands, Norway, Poland, Sweden, and United Kingdom, (Julich).
Fruiting body: effused, at first thin and pellicular, becoming thicker and ceraceous [waxy] in consistency; white to cream; "smooth or in the fresh state sometimes merulioid, when dry cracked, mostly transverse to the wood grain, separable in small pieces"; margin white, finely fibrillose under hand lens, (Eriksson), thin membranous patches, several centimeters in extent, attached loosely, consistency membranous, wax-like, and soft; whitish to cream; "smooth to slightly merulioid, somewhat fissured when dry, dull"; margin finely arachnoid [cobwebby], without rhizomorphs, (Breitenbach), spore deposit white (Buczacki)
Microscopic: SPORES 3-3.5 x 2-2.5 microns, elliptic to nearly round; smooth, with one oil droplet; BASIDIA narrowly clavate, mostly 20-25 x 4-5 microns, 4-spored; CYSTIDIA usually few, (sometimes absent), hyphal, 40-60(100) x 4-5 microns, projecting 10-30 microns, more or less encrusted, with septa and clamp connections; HYPHAE monomitic: subiculum hyphae 3-4 microns wide, rather straight and with sparse branching and anastomoses, with clamp connections; subhymenium hyphae 2-3 microns wide, densely interwoven, with clamp connections, "as a rule with crystalline deposits", (Eriksson), SPORES 3-3.5 x 2.2-2.5 microns, drop-shaped, smooth, inamyloid, colorless, with one droplet; BASIDIA 4-spored, 22-28 x 3.5-4.5 microns, narrowly clavate, basal clamp connection not seen; SEPTOCYSTIDIA often only a few, which moreover are hard to find, 50-65 x 4.5-6 microns, "cylindric, blunt, usually septate and with large clamps"; HYPHAE monomitic 2.5-4.5 microns wide, with clamp connections, (Breitenbach), SPORES 2.8-3.5 x 2-2.5 microns, inamyloid, (Julich)
Habitat / Range
on decayed wood, mostly of conifers, (Eriksson), Abies balsamea, Picea engelmannii, Picea rubens, Rhododendron sp., on branch, on log, associated with a white rot, (Ginns), fall, winter, spring, (Buczacki)
