Fruiting body: up to 2cm high, variable in shape, simple, subulate [awl-shaped], cylindric, or cylindric-attenuate, or forked and simply branched, occasionally palmate or short-stemmed with a folded or wrinkled cap, consistency firm-gelatinous, usually not distinctly rooted, but occasionally with a slightly bulbous base; yellow to orange-yellow when fresh, drying red-brown, (McNabb), 0.2-0.7(1)cm x 0.1-0.2cm, cylindric to awl-shaped spines with blunt to pointed, simple, rarely forking ends, cartilaginous, gelatinous; yolk-yellow to orange-yellow; smooth, lubricous, (Breitenbach), either smooth or longitudinally wrinkled, not obviously demarcated into stem and fertile part, although this may be more obvious with drying, (Reid)
Microscopic: spores 7-10(12) x 3-4.5 microns, cylindric to slightly curved-cylindric, thin-walled with thin septa, tinted, apiculate, becoming 1-septate at maturity, germination by colorless spherical conidia or by germ tubes; probasidia 20-35 x 3-4.5 microns, cylindric-subclavate, with basal septa, becoming bifurcate; hymenium smooth or occasionally folded or wrinkled, consisting of basidia and occasionally simple cylindric dikaryophyses; composition otherwise "homogeneous, of thin-walled, septate, roughened hyphae, showing in transverse section an organisation into three zones, clamp connections absent", (McNabb), spores 7-10 x 2.5-4(5) microns, cylindric-elliptic, slightly curved (allantoid), smooth, inamyloid, colorless, with one septum, with drops; basidia 30-40 x 2.5-4 microns, fork-shaped, without basal clamp connection; cystidia not seen; hyphae in part with thick gelatinized walls, 2-4 microns wide, clamp connections absent, (Breitenbach), spores yellow in mass, very pale yellow or colorless by transmitted light, (Martin)
Habitat / Range
on barkless branches of hardwoods (Acer, Alnus, Betula, Fagus, Gleditsia (honeylocust), Liriodendron, Populus, Quercus), less frequently on conifer wood (Juniperus, Pinus, Pseudotsuga, Tsuga), causes brown pocket rot and brown basal rot, (Ginns), single, gregarious, to clustered, on dead barkless hardwood, especially Quercus (oak), less frequently Fagus (beech), occasionally on conifer wood, (Breitenbach for Europe), summer and fall (Bacon)
