Summary:
The tiny fruitbodies of Tremella subencephala are known only on Acanthophysium lividocoeruleum, a species typical of rather xeric (dry) habitats, from a few collections in western Canada and Sweden. The description is derived from Bandoni(7).
T. subencephala has been found in BC, YT, and Sweden.
Fruiting body:
0.05-0.3cm wide, sometimes anastomosing and then up to 0.6cm long and up to 0.25cm high, pulvinate [cushion-shaped] to subglobose (nearly spherical), occasionally discoid, typically aggregated, gelatinous but the larger fruiting bodies often with a fleshy core, "frequently appearing substipitate because of slight upward growth of host tissue", the fruiting body "often surrounded by a whitish ring of tufted aerial hyphae on the host hymenium, the tufts consisting of mixed host/parasite hyphae, infrequently with small basidiomes interconnected by a thin film, that becomes horny, brownish on drying", some fruiting bodies "also containing a basal core of host hyphae and therefore not shrinking greatly on drying"; predominantly yellow, less frequently brown when dry
Microscopic:
spores 7.0-8.0 x 5.5-7.5 microns, nearly round to broadly elliptic or oval, germination not seen, conidia abundant, 3.0-6.5 x 3.0-5.0 microns, round to elliptic, "borne on branched conidiophores, each conidium subtended by a clamp, the wall thick, smooth"; probasidia sparse, 10.5-14.0 x 10.0-11.0 microns, "borne on the same hyphae as conidia, subglobose to obovoid or ellipsoid, 4-celled, the walls often thickened at maturity", epibasidia 2.0-2.5 microns wide; hyphae 1.5-4.0 microns wide, branched, with clamp connections and haustorial branches
