Description:Ramaria rubrievanescens Marr & Stuntz, 1973. Bibl. Mycol. 38: 41.
Fruit bodies up to 9 x 6 cm, obpyriform in outline. Stipe single, stout to massive, smooth, rounded below, apparently without aborted branchlets (adequate statistical sampling not available), off-white where protected, with limited stains to maroon ("deep Corinthian red"); flesh white, dry, solid, soft, reddish under surface stains. Major branches 3 or 4, stout, ascending but not erect, more or less terete, fleshy beige ("pinkish buff," 5A4); branches in 4-6 ranks, terete, concolorous with major branches; axils rounded to lunate; internodes long below, diminishing rather abruptly upward; apices minutely digitate when young, in age knobby, buffy pink to pallid rose when young ("light Corinthian red," "vinaceous pink," fading to "buff pink," 8A4). Odor negligible; taste faintly bitter, acrid on tongue.
Macrochemical reactions: FSW, FCL: positive but not intense; GUA: negative on branch sections, weak azure on stipe surface; KOH: yellowing; PYR, NOW negative; IKI: positive slowly, green-purple.
Tramal hyphae of upper branches up to 10 gm diam, hyaline, thin-walled, clamped, parallel, free; septal inflations up to 15 ttm broad, locally thick-walled (wall up to 1 jm thick), extensively ornamented; gloeoplerous hyphae rare, undelimited, 1.5-3 pm diam, yellow-refringent. Subhymenium rudimentary. Hymenium thickening; basidia 55-65 x 7-8 µm, clavate, clamped; contents homogeneous; sterigmata 4, apical, straight.
Spores 10.4-13.7 x 4.0-4.7,m (E = 2.23-3.09; Em =2.67; Lm = 11.77 µm), mummy-shaped, smooth in profile, "light salmon orange" in prints; contents with one to several dark, lobed inclusions; wall up to 0.2 µm thick; hilar appendix gradual, with no throat; ornamentation of delicate, closely spaced striae in an abaxial-distal to adaxial-proximal orientation.
Commentary
The description by Marr and Stuntz (1973) matches Nova Scotian material almost exactly. Apices are rosy, fading quickly, stipe stains are maroon, spore statistics are very close, and stipe flesh is slowly amyloid. I am wary of using this name capriciously, however, for R. rubripermanens and R. rubrievanescens have become catchalls for specimens with reddish branch tips, but spore dimensions not matching those of R. botrytis. One key may be amyloid stipe flesh, but little note of this character has been taken by most workers. All told, it is difficult to judge the distribution of a taxon when its name is used loosely by workers the world over.
McAfee and Grund (1982) reported R. botrytis from Nova Scotia. Fruit bodies of this species exhibit copious abortive branchlets and dark red to purplish apices. While I did not collect it, it is to be expected in Nova Scotia as part of groups 2 and 3 (see Introduction). Equally, McAfee and Grund reported R. rubripermanens, which differed from R. botrytis and R. rubrievanescens by nonstaining stipe surface and flesh.
