Description:Ramaria aurea (Schaeff.) Quelet. 1888. Flore Mycol., p. 467.
--- Clavaria aurea Schaeffer, 1774. Fung. Bav., index p. 121, p. 287.
Fruit bodies (Fig. 11) up to 14 x 6 cm, ellipsoid in outline. Stipe single, fleshy, up to 40 x 20 mm, tapering downward, almost pointed at very base, involving significant substrate, smooth above, minutely felted below, white where protected, unchanging when handled or bruised, off-white above; flesh solid, white, drying firm but easily pierced; upper stipe and lower major branches bright yellow ("maize yellow," "baryta yellow," "antimony yellow"); major branches several, hardly terete, up to 5 mm thick, ascending but not strict, often rebranched from base to give a bushy appearance; branches in 5-7 ranks, more or less terete, pallid salmon ("light ochraceous salmon"); flesh concolorous to hymenium outward, white inward; axils rounded; internode ratio diminishing gradually at maturity; apices rounded-digitate, often mittenshaped at maturity, rich ochraceous yellow ("apricot yellow"). Odor very faintly aromatic; taste negligible.
Under Picea and Fagus.
Macrochemical reactions: FSW, FCL, PYR: positive; GUA: weakly positive; KOH, NOH: negative.
Tramal hyphae of stipe 2.5 -15 µm diam, hyaline, clampless, interwoven, thin-walled, free; ampulliform inflations and gloeoplerous hyphae not observed. Tramal hyphae of upper branches: medullary hyphae up to 12 pin diam, hyaline, thinto slightly thick-walled (wall up to 0.4 µm thick), parallel, clampless, often constricted at septa; cells cigar-shaped; cortical hyphae up to 3.5 µm diam, otherwise similar. Hymenium thickening; basidia 65-75 x 7-9 µm, clavate, sometimes somewhat inflated apically, clampless; contents homogeneous, hardly cyanophilous; sterigmata 4, apical, almost straight.
Spores (Fig. 12) 9.7-12.6 x 4.7-5.4 µm (E = 2.00-2.62; Em = 2.24; Lm = 10.95 µm), boletoid, cylindrical to narrowly ellipsoid, obviously roughened in profile, "chamois" in prints; contents ochraceous, with one to several obscure dark inclusions; wall up to 0.3 µm thick, thinner apically; hilar appendix obvious, eccentric, narrow; ornamentation of complex meandering ridges or abundant warts in a generally abaxial-distal to adaxial-proximal orientation; suprahilar struma often present but small.
Commentary
This is the first bonafide record of the species from North America. All previous authors have treated the name folkloristically, as representing a golden fruit bodied taxon, but Petersen (1974) redescribed the species from topotype material, drawing attention to the following characters: (i) color pattern (lower branches and apices yellow, branches dull salmon); (ii) clampless state; and (iii) spore statistics and ornamentation. By comparison, spores of Bavarian material were 10.7-13 X4.4-5.9iLm (E= 1.94-2.75; Em=2.32; Lm= 11.21 pm). In that report colors were taken from Seguy (1936), but comparison of that manual with Ridgway (1912) confirms an extremely close match between the colors reported above and those of Bavarian fruit bodies.
Citation of the epithet no longer requires reference to Fries, as used by Petersen (1974). Fries did not sanction the epithet in Systema Mycologicum, so Schaeffer's (previously devalidated) name is valid.
