Species Information
Summary: Features include thin to rather thick, waxy-gelatinous-mucous fruitbodies that are colorless, pinkish, grayish, or somewhat olive to lead-colored, the surface waxy and bumpy or even, growth on wood, and microscopic characters including basidia arising from erect hyphae of rather large diameter.
The distribution includes ON, GA, IA, LA, MN, OH, WY, HI, and Europe including Poland, (Martin, G.W.). It also occurs in NC, NY, TN, and VT, (Ginns). There are collections from BC identified by R. Bandoni at the University of British Columbia.
Fruiting body: thin to rather thick; colorless, pinkish, grayish or olivescent to plumbeous, drying to a colorless, yellowish, reddish or dark varnish-like film; "mucous or waxy-mucous, undulate or even", (Martin, G.W.), soft-gelatinous or mucous-gelatinous, rather thin; gray to brown; surface undulate or bumpy, (Olive(3)), 0.004-0.01cm thick, indefinite in extent, "on the under surface of an old oak limb where it covered the bark and some old leather-fungi over a considerable area"; sordid gray to purplish gray; "gelatinous, and with an undulate or rugose surface", drying to "a thin, black or very dark gray, rough and often carbonaceous layer", (Olive(5))
Microscopic: SPORES 6-10 x 4-6 microns, nearly round to ovate, white in mass; PROBASIDIA clavate to clavate-capitate, epibasidia 4 or more, finally ovate with a long cylindric or somewhat subulate [awl-shaped] filament tipped with a distinct sterigma; GLOEOCYSTIDIA lacking; HYPHAE erect, branching, with or without clamp connections, (Martin, G.W.), SPORES (5)6-10(12) x 4-6(8) microns, nearly round to ovate; BASIDIA becoming 8-18(30) x (4.5)6-9(12) microns, each usually producing 4 epibasidia, 9-15 x 2.5-5 microns; HYPHAE 2-7 microns wide, erect, branching, thin-walled, (Klett), spores 3.9-5.2 x 5.9-9.1 microns, nearly round to somewhat cylindric; basidia arising from erect hyphae of rather large diameter, a helpful character in identification, (Olive(3)), SPORES 5.9-8.4 x 4.5-5.9 microns, mostly nearly round to obovate, germinating by repetition; BASIDIA mostly in fascicles, forming a rather compact hymenium, 10.4-17.1 x 8.1-9.6 microns, clavate or clavate-capitate, epibasidia (2)4, 8.1-12.6 x 6.3-7.2 microns, (Olive(5))
Habitat / Range
bark and barkless wood of coniferous and hardwood species, and on old fruitbodies of tough or woody hymenomycetes, (Martin, G.W.), Betula nigra (River Birch), Carya sp. (hickory), Cytisus sp. (broom), Liriodendron tulipifera (Tulip-poplar), Mimosa sp., Quercus sp., Quercus rubra (Northern Red Oak), (Ginns), barked and debarked hardwood (oak, tulip poplar, river birch, hickory, and Mimosa), fall to spring, (Olive(3) for GA)
