Description:Ramaria sanguinipes Petersen & Zang, sp. nov. Figs. 6 , 7
Fruitbodies (Fig. 6 ) up to 6 x 5 cm, curved obovate to generally circular, in outline, repeatedly branched. Stipe single, and then stout (up to 30 x 30 mm) or fasciculate, and then stout (up to 30 x 14 mm), smooth to somewhat marbled, off-white to ivory-colored, not canescent, without aborted branchlets, rounded at base, tapering sharply downward, stained maroon ("madder red") at base, and suffused in this color upward; flesh solid, dry, punky, marbled, deep pinkish red downward under stained surface. Major branches several, short when young, lengthening significantly over time, ivory-colored; branches in 3-6 ranks, abruptly shorter than major branches, ivory-colored below, pallid clear yellow ("baryta yellow") upward, eventually fading to pallid ocher; axils narrowly rounded; internodes diminishing abruptly above in adolescence, less so at maturity; apices slender, small, not terraced at any age, somewhat divaricate in some specimens, dichotomous, pallid clear yellow ("baryta yellow"). Taste mildly fabaceous; odor weakly aromatic.
Macrochemical reactions KOH=orange; FCL=green; GUA, NOH, PHN, ANW, PYR, IKI=negative.
Tramal hyphae of stipe up to 14 µm diam, hyaline, thin-walled to locally somewhat thick-walled (wall up to 0.5 µm. thick), virtually unclamped, not parallel, Tramal hyphae of upper branches up to 10 µm diam, hyaline, thin walled, parallel; clamp connections occasional on medullary hyphae, common on cortical hyphae. Subhymenium extensive, hyphal. Hymenium thickening; basidia 40-45 x 8-10 µm, clavate, clamped invariably; contents granular to multiguttulate; sterigmata 4 , more or less straight, somewhat divergent.
Spores (Fig. 7) 9.4-11.5 x 4.3-5.0 µm (E=2.00-2.58; Em=2.28; Lm =10.47 µm), ellipsoid to narrowly ovate, often with suprahilar depression, conspicuously rough in profile; content 1-several guttulate, the guttules deep ocher to brown; wall up to 0.3 µm thick; hilar appendix small but conspicuous; ornamentation of cyanophilous, complex, anastomosing ridges and a few isolated warts up to 0.3 µm high.
Commentary: As have previous workers, we perceive complexes of taxa whose fruitbodies are similar, and envision these under a category called "consociation." Unlike a stirps (in the sense of Smith, i. c. 1979), which represents what a mycologist views as a "natural" cluster of taxa, my concept comprises taxa which may be related or not so, but which have conspicuous characters fields in common. Thus, the Ramaria sanguinea consociation includes the "type species," R. sanguinea (Pers.) Quel., as well as R. xanthosperma (Peck) Corner and R. rubiginosa Marr and Stuntz, all clampless, and R. eosanguinea Petersen, which is clamped, as well as some undescribed taxa,
Ramaria sanguinipes obviously fits in this consociation, sharing the maroonstaining base, pale branches and yellow apices.
Singh (1977), under R. eosanguinea, redescribed a collection by Thind and Dev (1957) from the Mussoorie Hills of India, in which the stipe tramal hyphae were clampless but the basidia were clamped. The authors are inclined to think that that collection is contaxic with R. sanguinipes, for all microscopic characters, and almost all macroscopic characters match. Thind and Dev reported of their fruitbodies "... yellow, later turning light dark red at the top, on drying reddish brown to dark brown ..•" " ..flesh white, on bruising slowly turning red to dark red-" Sometimes fruitbodies of the "R. 'sanguinea consociation" tend to blush red upwards in age, especially if kept in a confined place after picking, not unlike some members of the striate-spored complex (i. e. R. holorubella), which may account for their report.
At any rate, the Yunnan specimen does not represent any taxon in the consociation to our knowledge, and it is here proposed as new. The type specimen was acquired in the market in Szemao, and so must be presumed edible.
It was reported to have been collected under Pinus szemaoensis Chen and Lau. and Castanopsis argyrophylla King ex Hook. f.
Specimen examined: Yunnan, Szemao, 20. IX. 83, no. 45677 (Holotype, TENN; 10418 Isotype, HKAS).
