Summary:
Also listed in Crusts category. Features include 1) pustular, soft to firm gelatinous, colorless to pale yellow fruitbodies with a granulose surface, in older specimens becoming confluent to form a continuous layer, 2) growth on decaying herbaceous stems and 3) microscopic characters including fusiform-curved to cylindric-curved spores and absent clamp connections. The description is derived from Wells(6).
Efibulobasidium albescens is known from Azerbaijan and France, (Wells). There is a collection from BC by Robert Bandoni at the University of British Columbia.
Fruiting body:
arising as small pustules, 0.01-0.3cm in diameter, "becoming confluent in older specimens to form a continuous layer with abrupt margins", fruitbodies 0.018-0.2cm thick, consistency soft to firm gelatinous, loosely attached; colorless or translucent to pale yellow; "surface granulose, becoming undulate in continuous specimens"; drying evanescent [disappearing] or forming colorless or amber, vernicose [varnish-like] patches
Microscopic:
spores 15-21(25) x 5.5-7.5 microns, fusiform-curved to cylindric-curved, capable of germinating by repetition; hypobasidia 15-22(25) x (10)12-16 microns, epibasidia "tubular, gradually enlarging apically, bulbous adjacent to sterigma", up to 130 microns long, 2-3.5 microns wide and up to 5 microns wide adjacent to sterigma, probasidia at first pyriform to clavate, becoming ovoid, to narrowly ampulliform, or rarely fusiform, finally subspherical, ovoid, obovate, to clavate, pyriform or rarely fusiform, forming 2-4 hypobasidial segments, "adjoining walls of hypobasidial segments longitudinally to obliquely oriented"; hymenium distinct, consisting of a zone of developing basidia covered by a layer of dikaryophyses 50-90 microns in section, dikaryophyses "at first distinct, simple to little branched, some segments curved", 1-3 microns in diameter; subhymenial hyphae at first distinct, thin-walled, branching, without clamp connections, 1.5-4 microns wide; pustular fruitbodies "consisting of branching hyphae radiating from the substrate and terminating in a convex hymenium of fertile hyphae and dikaryophyses", in continuous fruitbodies "margins of original pustules outlined by layers of collapsed, yellowish basidia"; collapsed basidia are present in most areas of the ascending hyphae
