Summary: Features include a small cup with white flexuous [wavy] hairs on the exterior and the margin, a bright orange-yellow upper surface, a short stem, gregarious growth on bark and wood of conifers, and microscopic characters. This is the most common Lachnellula in the Pacific Northwest (Trudell(4)). It is found in WA (Kanouse), NF, CO, MT, and PA, (Seaver). There are collections from BC at the Pacific Forestry Centre and (as Dasyscyphus) the University of British Columbia.
Upper surface: reaching 0.4cm across but often much smaller, at first nearly spherical, becoming expanded and shallow cup-shaped, or nearly flat; spore bearing surface bright orange-yellow; margin fringed with white hairs, (Seaver), creamy yellow (Trudell)
Underside: with white flexuose hairs (Seaver), white or pale yellow (Trudell)
Stem: short-stemmed (Seaver)
Microscopic: spores 6-8 x 2.5-3 microns (Trudell), spores 6-10 x 3-4 microns, narrow-elliptic, colorless, uniseriate or biseriate; asci reaching a length of 60-95 microns and a width of 3-4 microns, cylindric or subcylindric; paraphyses clavate, reaching a width of 2-5 microns at tip; hairs reaching a length of 100 microns and a width of 2-3 microns, colorless, blunt or attenuated, externally covered with coarse granules, (Seaver)
Habitat / Range
gregarious on bark and wood of conifers (Seaver), on branches of Abies (fir), Pinus (pine), and Tsuga (hemlock), (Trudell)
