Summary: Stromatocyphella conglobata produces minute basidiomycete cups that are densely gregarious on a common stem, (pendant clusters on gelatinous trunk), protruding from lenticels or cracks in the bark of dead branches, usually of alder.
Microscopic: spores 7-10 x 3-3.5 microns, cylindric, smooth, apiculate, colorless; basidia appearing at first as fusiform (spindle-shaped) structures with granular contents, finally 20-25 x 7-9 microns, 4-spored, with sterigmata 6-7 microns long; clamp connections present in subhymenial tissue, surface hairs irregular in length, granule incrusted, with clamp connections, (Cooke), (6.0)8.0-10.0 x 3.0-3.8 microns, cylindric, dented on one side or slightly curved, smooth, inamyloid; basidia 4-spored, 23-28 x 6-7.5 microns, colorless, clavate; cystidia not seen, (Thorn)
Notes: It is found at least in BC, NB, ON, PQ, MI, NH, NY, and PA, (Ginns).
