Description:Ramaria rasilispora sp. nov. var. rasilispora (P1. XXII Fig. 84)
Holotypus M-956 in area ambusta in monte Evergreen nominato, prope oppidum Skykomish nominatum in comitato Snohomish pagi washingtoniaci 5/20/68 lectus, in herbario SUCO conservatus.
Basidiocarp: Habitat: terrestrial, collected in the spring and summer in coniferous woods. Color: stipe and lower branches of the fresh fruiting body offwhite where underground, young branches dull "light orange" (5A4-5) to "apricot yellow" (5B6) maturing pale "grayish orange" (5B4-5), apices concolorous or turning "dark brown" (7E6) with age or on drying, context white. Dried specimens "pale yellow" (4A3) to "grayish orange" (5B3-5), apices sometimes darker and the context "yellowish white" (4A2-4). Taste: not distinctive. Odor: mild to distinctively
fungoid, or somewhat unpleasant. Form: fruiting bodies large, broad, 5-15 x 6-15 cm.
Stipe single, conical, stout, 3-C1 x 2.5-5.5 cm; in mature basidiocarps branching up to 7 times from the base, nodes polychotomous or dichotomous, axils acute or turbinate, branches straight,. moderately divergent and thickish in appearance, primary branches very stout, 2-4,cm diam,, upper ones mostly 0.2-1.5 cm diam, internodes lengthening up to 5 cm in mature fruiting bodies polydigitate near the apices; apices obtuse to rounded. Consistency-fleshy-fibrous or punky-fibrous in the stipe when fresh, drying hard to.chalky-friable.
Macrochemical Reactions: Context of stipe weakly amyloid, the reaction slow, requiring about 1 1/2 hrs; no significant color changes occurring within 15 min of application to branch sections of pyrogallol, a-napthol, guaiac, guaiacol, phenol and aniline.
Microscopic structures: Spores: average 9.5 x 3.4 µm, range 8-11 x 3-4 µm, cylindrical, entirely smooth to very finely warted, warts cyanophilous, obscure under 1000 X magnification. Hymenium: basidia clavate, 47-60 x 8-10 µm, basally clamped, 2-4-sterigmate, mostly 4; sterigmata mostly 4 µm in length (-7 µm), slightly incurved or straight, slightly divergent; hymenium about 70 µm thick and the subhymenium 20-25 µm thick. Subhymenial hyphae: interwoven, 2.5-4 µm diam, clamped, thin-walled. Contextual hyphae: surface of the stipe with a layer about 100-300 µm thick of loosely interwoven hyphae of narrow diam, 3-4 µm, the context proper interwoven, with noninflated cells up to 12 µm diam, context of the branches.parallel, non-inflated, 4-9 µm diam, walls smooth to slightly fluted, thin, cyanophilous, cyanophilous globular inclusions common, ampulliform inflations near septa 8-18 µm diam, walls of the swellings nearly smooth in the branches, distinctly ornamented in the stipe; clamps abundant; gleoplerous hyphae rare, 3-5.5 µm diam or up to 12 µm diam in localized bulbous regions.
