Ramariopsis ovispora R.H. Petersen 1988

Fruit bodies up to 80 x 7 mm, simple clubs, broadly fusiform, usually flattened and often sulcate, fasciculate in groups of up to 7 individuals, when young brilliant orange ("cadmium-orange"), fading slightly, egg-yolk yellow to golden yellow ("orange", "deep chrome") all over, with the stipe often somewhat brighter than club, fleshy, occasionally bifurcate apically, and then the branches divergent-ascending, cornute; flesh whitish inward, concolourous to hymenium outward. Stipe up to 4 mm thick, more or less terete, not well marked from club, arising from multiple primordium below substrate level. Taste and odour negligible.

Macrochemical reaction: FCL = dingy slate-green. Tramal hyphae of club 2-8 Erin diam., hyaline, clamped, relatively uninflated, free, more or less parallel, loosely packed. Subhymenium rudimentary. Hymenium thickening; basidia 70-100 x 8-10 gm, narrowly clavate, stiff when developing, collapsing after spore discharge, clamped; contents obscurely refringent to multiguttulate at maturity; sterigmata 4, stout, divergent.

Spores 6.1-7.2 x 5.0-6.1 Erin (E =1.13-1.33; E'° =1.22; L'" = 6.73 gm), broadly ovate to subtriangular in profile, smooth, thin-walled, hyaline; contents obscurely refringent when mature; hilar appendixvery stout, up to 2 gm long, conical; nucleus 1.

Receptacula ad 80 x 7 mm, simplicia, late fusiformia, saepe sulcata, juniora aurantia clara, vetustiora aureo-flava; hymenio in FCL cinereo-olivaceo. Hyphis fibulatis; basidiis 70-100 fun longis. Sporis late ovatis ad subtriangularibus, laevibus, hyalinis, 6.1-7.2 x 5-6.1 fun; apiculo conico, ad 2 fun longo.
If this taxon had globose spores, it would be extremely similar to Ramariopsis fusiformis (Sow.: Fr.) Pet. Fruit bodies of the five specimens I have seen are surely so. Nevertheless, basidiospores are not globose, but tend towards ovate or subtriangular, not unlike those of R. depokensis (q.v.).
