Summary: features include 1) growth on decaying hardwood, 2) waxy-gelatinous fruitbody that is colorless to light gray or buff or nearly white, usually with a faint pinkish tinge, the surface granulose to pruinose, margin tightly attached but not easily apparent, 3) spores allantoid, 4) basidia longitudinally septate, developing on fertile hyphae that proliferate through the subbasidial clamp connection, 5) the hymenium consisting of a zone of basidia below a layer of dikaryophyses that are simple to sparingly long-branched, nodulose to short-branched apically; collections examined from BC, WA, OR, CA, (Wells), also found in NB, NS, ON, GA, IA, LA, (Ginns)
Fruiting body: spreading to form a thin, effused layer or arising as erumpent, hemispherical pustules that become confluent to form a continuous resupinate layer up to several centimeters long, consistency soft to firm waxy-gelatinous, in section 0.0035-0.078cm thick; c
Microscopic: SPORE (10.5)12.5-19(21) x (4.5)5-6.5(7.5) microns, cylindric-curved to allantoid, guttulate, capable of germinating by repetition; PROBASIDIA at first cylindric or broadly clavate, "proliferating through or near subbasidial clamps", hypobasidia with distinct basal clamp, forming (2)4 hypobasidial segments, "becoming oval, ovate, obovate to clavate, less often subglobose, very rarely pyriform with enucleate stalk", (11.5)12.5-20(24) x (9.5)10.5-16 microns, epibasidia 10-87.5 x (2)2.5-4.5 microns (when mature), "tubular to flexuous, usually enlarging apically, sometimes becoming delimited from hypobasidial segments"; cystidioles sparse to absent, 24-85.5 x 2.5-8(9.5) microns, subcylindric, subfusiform, subclavate, or flexuous [wavy], sometimes branching apically, thin-walled with staining contents, intergrading with simple dikaryophyses; probasidia and hypobasidia forming a well defined zone 25-50 microns thick and covered by a zone of dikaryophyses (9)12-30 microns thick; DIKARYOPHYSES 1-2.5(5) microns in diameter, "simple to sparingly long-branched, nodulose to short-branched apically, usually distinct"; fertile hyphae 2-5 microns in diameter, "sometimes branching, giving rise to both basidia and dikaryophyses"; SUBHYMENIAL HYPHAE (1.5)2-4(5.5) microns wide, "usually distinct, with clamps; thin-walled, infrequently becoming slightly thick-walled adjacent to the substrate"; in section fruitbody "consisting of a loose, ascending hyphal layer arising directly from the substrate" and terminating in the hymenium; "mineral accumulations present or absent in the trama, portions of the substrate sometimes incorporated in the ascending layer", (Wells)
