Species Information
Summary:
Also listed in Crust Category. It grows flat on wood but a cup-like structure develops. Features include 1) (the most distinctive feature) a flaring cup-shaped structure about 0.5cm across, on the upper side of twigs and small branches, in which develops a bright salmon egg-like sclerotium 0.2-0.3cm across, that when mature is loosely attached at the base and easily removed (it is thought that this sclerotium is disseminated by raindrops to other wood where the fruitbody grows), 2) the resupinate fruitbody that grows widely spread out or in irregular patches, and is soft-membranous in consistency, separable, pink in color, with an irregular margin that is abrupt or thinning out, 3) spores that are ovoid with a conspicuous apiculus, smooth, inamyloid, and colorless, 4) basidia arising from deep in the subiculum, 5) abundant paraphyses with irregular peg-like branches, and 6) hyphae with clamp connections. The description is derived from Jackson(5).
Microscopic:
spores 12-16 x 8.5-11 microns, ovoid, slightly flattened on one side, with conspicuous apiculus, smooth, inamyloid, colorless, thin-walled; basidia 4-spored, arising from deep in the subiculum, 80-100 x 8-10 microns, long cylindric or subclavate, more or less flexuous [wavy], sterigmata subulate, arcuate, 7-8.5 microns long; paraphyses abundant, 1.5-2 microns wide, nodulose, with irregular peg-like branches; subiculum made up of hyphae 3-4 microns wide, thick-walled, arranged more or less horizontally in lower part, interwoven in subhymenium, with regular clamp connections, (Jackson)
Notes:
Corticium minnsiae is found in BC, OR, also ON, PQ, CA, ME, MI, NC, NH, NY, PA, TN, VT, (Ginns), and WA (I. Gibson, pers. comm.).
Habitat and Range
Habitat
a cup-shaped structure on the upper side of twigs and small branches contains sclerotium in August and early September, but is shriveled and dried later in the fall after the sclerotium has been disseminated (perhaps by a similar splashing mechanism from raindrops to the one operating in bird''s nest fungi), the resupinate fruitbodies develop in the fall but are generally sterile at first, fruiting in late May or June of the following year; found on Tsuga canadensis (Eastern Hemlock), Pinus contorta (Lodgepole Pine), Pinus ponderosus (Ponderosa Pine), Pseudotsuga menziesii (Douglas-fir), Abies lasiocarpa (Subalpine Fir), (Jackson), also Tsuga heterophylla (Western Hemlock), (Ginns)
