Species Information
Summary:
Also listed in Crusts category. Features include 1) small, pustular, waxy gelatinous, colorless to pale amber fruitbodies with a finely granulose surface, in older specimens becoming confluent to form a continuous layer, 2) growth on decaying wood with bark in place or on leaves, and 3) microscopic characters including cylindric-curved spores and absent clamp connections. The description is from Wells(6) except where noted.
Microscopic:
spores (8)9-14 x (3.5)4.5-6(7) microns, cylindric-curved and flattened adaxially, "capable of germinating by repetition"; hypobasidia (7.5)8-13(14) x (7.5)8-12 microns, epibasidia up to 100(255) microns long, "tubular, usually enlarging towards apices", probasidia at first cylindric, then clavate, broadly fusiform or ampulliform, finally subspherical, ovoid, obovate, or clavate, "forming 2 or 4 hypobasidial segments, adjoining wall of hypobasidial segments longitudinally to obliquely oriented"; hymenium distinct, with developing basidia in a zone 20-55 microns in section, covered by a layer of dikaryophyses 20-65 microns in depth, dikaryophyses "usually abundant and distinct, branching, somewhat nodulose near apices, some segments curved", 1-1.5-3 microns thick, "fertile hyphae proliferating laterally from the apical region of subbasidial segment", 1.5-2-3 microns in diameter, without clamp connections; subhymenial hyphae "without clamp connections, usually distinct, thin-walled", 1.5-3 microns wide; "in pustules hyphae arising from a restricted region of the substrate, then expanding and forming a loosely interwoven and ascending layer of hyphae" terminating in hymenium, "in continuous specimens ascending, interwoven layer continuous with a poorly defined basal layer that is very loosely attached to substrate, collapsed basidia scattered throughout ascending, interwoven layer"
Notes:
Efibulobasidium rolleyi is found in IA and Tahiti, (Wells). There are collections from BC and CA by Robert Bandoni at the University of British Columbia.
