Summary:
Features include 1) resupinate growth on conifer wood, 2) a fruitbody that is whitish to pale cream-colored, rather thick in the middle and conspicuously grandinioid, the subiculum scarcely developed, 3) spores that are broadly elliptic and inamyloid, 4) 4-spored basidia, 5) cylindric cystidioles projecting about 15 microns beyond the hymenium but at times poorly developed and not always easy to find, and 6) hyphae that are colorless, thin-walled, branching at right angles, with a visible central pore in the septa, but lacking clamp connections.

Microscopic:
SPORES 5-6 x 3-4 microns, broadly elliptic, inamyloid, thin-walled; BASIDIA mostly 4-spored, 13-16 x 5-6 microns, without basal clamp connection, sterigmata about 3-5 x 0.5-0.8 microns; cystidioles about 20-30 x 4-5 microns, projecting about 15 microns beyond the hymenium, more or less cylindric, thin-walled, at times only poorly developed, not always easy to find; hyphae 3-5-5.5 microns wide, branching at right angles, colorless, thin-walled (about 0.3 microns), central pore distinctly visible going through the cross-walls (septa), clamp connections absent

Notes:
Athelia cystidiolophora have been found in BC, Czechoslovakia, and Estonia, (Julich).
