Fruit bodies up to 30 x 10 mm, branched, very slender, arising from small white mycelial pads. Stipe up to 14 x 1 mm, discrete, off-white when young, slowly becoming cream colour ("cream buff') or pallid tan ("tawny") from the base, and eventually these colours suffuse upward through the branches. Branches dichotomous throughout, less than 1 mm thick, erect to ascending, off-white to ivory coloured ("cream-colour", "pale ochraceous salmon"); axils rounded. Apices off-white, remaining so, awl-shaped. Odour and taste negligible.

Macrochemical reaction: FCL = grey to slate-green. Tramal hyphae of branches hardly inflated, 3-8 gm diam., hyaline clamped, thin-walled, free. Subhymenium extensive, pseudoparenchymatous. Hymenium thickening; basidia 25-40 x 6-7 l.m, subcylindrical, clamped; contents homogeneous to multiguttulate at maturity; sterigmata 4, curved-ascending.

Spores 3.6-4.0 x 2.5-3.2 gm (E =1.22-1.57; E°' = 1.38; L°° = 3.77 um), ellipsoid, smooth, hyaline, thin-walled, weakly dextrinoid; contents uniguttulate; hilar appendix prominent, conical.

Receptacula ad 30 x 10 mm, ramosa, tenuia; stipite et ramis cremeis; apicibus eburneis; hymenio in FCL cinereo-viridi. Hyphis fibulatis; basidiis 25-401tm longis. Sporis ellipsoideis, laevibus, hyalinis, leniter dextrinoideis, 3.6-4.0 x 2.5-3.2 gym.

This will be very difficult to distinguish from Ramariopsis minutula and R. aggludnata in the field, but the free tramal hyphae separate it from the latter, and larger spores from the former. Although fruit bodies dry to a sordid orange¬ochraceous colour, when a portion is placed in 2% KOH, a canary-yellow pigment leaches into the liquid, a phenomenon not shown bythe other two similar taxa. Spores of R. cremicolor are not strongly dextrinoid, but are as reactive as any in the genus. In some spores there may be a very weak amyloid reaction of the spore wall.
