Summary:
Also listed in Corals category. Calocera viscosa is a yellowish coral-like mushroom, with antler-like branching, tough gelatinous consistency, and viscid surface. According to McNabb it is characterized among Calocera species by large, usually dichotomously branched fruiting bodies, 1-septate spores, and lack of clamp connections, and when present a stout rooting base.

Microscopic:
spores (8)9-12.5(14) x 3.5-4.5(5) microns, cylindric to slightly curved-cylindric, "thin-walled with thin septa, faintly tinted, apiculate", becoming 1-septate at maturity, germination by colorless spherical to nearly spherical conidia or by germ tubes; probasidia 23-42 x 3-4.5 microns, cylindric-subclavate, with basal septa, becoming bifurcate; hymenium consisting of basidia and occasionally simple cylindric dikaryophyses; composition otherwise "homogeneous, of thin-walled, septate, typically roughened hyphae, showing in transverse section an organization into three zones, clamp connections absent", (McNabb), spores (7)8-10 x 3.5-4.5 microns, elliptic to slightly allantoid [curved sausage-shaped], smooth, inamyloid, colorless, with drops, with one septum when mature, sometimes forming nearly round secondary spores; basidia 40-50 x 3-4 microns, fork-shaped, without basal clamp connection; cystidia not seen; hyphae 3-5.5 microns wide, "forked and sometimes with anastomoses, septa without clamps, thin-to thick-walled", (Breitenbach), spores deep ochraceous in mass (Martin), spore deposit orange-yellow (McKnight), spores form on all sides of mushroom, (Lincoff(2))
