Species Information
Summary:
Features include 1) resupinate growth on rotten wood, 2) a thin, waxy, tightly attached fruitbody that is whitish to gray becoming buff, with a pruinose surface, 3) spores that are nearly round, minutely apiculate, and colorless or guttulate, and germinate by repetition, 4) erect fertile hyphae with 2-3 basidia clustered at top and many collapsed basidia sheathing the sides, each new basidium splitting longitudinally into 2 to 4 cells, and 5) gloeocystidia that are subcylindric, colorless to yellow brown, and not emerging.
Microscopic:
SPORES 4-6.5 microns, nearly round, minutely apiculate, colorless or guttulate, germinating by repetition; fertile hyphae 1.5-2.5 microns wide, erect, tortuous, arising almost directly from the wood to the surface, with 2-3 basidia clustered at the apex and a sheath of collapsed basidia down the sides, PROBASIDIA 8-11-13 x 6-8 microns, "at first obovate, finally elongate-urniform", "becoming indistinctly longitudinally septate, 2-4 celled", epibasidia 5-9 microns long, subulate, at first divergent then incurved; GLOEOCYSTIDIA 15-50 x 3.5-7 microns, sinuous, subcylindric, with contents at first colorless, later yellowish brown, often fragmented, reaching the surface only in young fruitbodies and never emerging, (McGuire), SPORES round 5-7 microns in diameter, or nearly round 5-7 x 4-5 microns, smooth, with obscure mucronate apiculus, germinating by repetition or by germ tube, apparently through the apiculate end; PROBASIDIA 7.5-10.5 x 6-7.5 microns, pyriform to obovate, mature basidia 8-14(15) x 6-8 microns, "urniform, elongate, indistinctly longitudinally septate", at first 2-celled to 3-celled, finally 4-celled; GLOEOCYSTIDIA 10-45 x 3-6 microns, (Luck-Allen)

Habitat and Range
SIMILAR SPECIES
Basidiodendron caesiocinerea has round spores that are minutely roughened and provided with definite blunt peg-like apiculi (the apiculus of B. eyrei shows up as a slight hump on the spore), and B. caesiocinerea also has larger more elongate-urniform basidia, and wider gloeocystidia, (from Luck-Allen). B. eyrei is distinguished from B. caesiocinerea by its usually more elongate basidia and its smaller, minutely apiculate spores, (McGuire). Basidiodendron fulvum (at least as Basidiodendron grandinioides) has spores measuring 3 x 2.5-3 microns, that are elliptic, with the shortest axis often through the minute apiculus, (from Luck-Allen). Basidiodendron cinerea has spores 8-11 x 6-8 microns, (from Luck-Allen). Basidiodendron pini has basidia generally more than 20 microns long, and fertile sheaths are not sheathed by involucres of collapsed basidia, (from Luck-Allen).
