Basidiocarp: Habitat: terrestrial, growing under Western Hemlocks. Color-base of fresh fruiting body white or bruising brown in places, immature branches "maize yellow" '(4A6), during maturation turning first "golden yellow" (5B7) and finally."yellowish or reddish brown" (5-6E,F5-6; 7-9E6), apices retaining a "maize" or "golden yellow" coloration or eventually becoming subconcolorous brown, any part of the basidiocarp quickly bruising "brown" or "slightly reddish brown" (7-9E4-5) with handling, context brownish white, immediately turning darker when cut. Base of dried basidiocarps white where covered by tomentum, immature branches "grayish yellow" (4B5).and apices "amber" or "banana yellow" (4B6-7), mature branches and apices drying "brown" to "dark brown" (6-7E,F5), context brownish white to brown. Taste: slight to distinctly bitter. Odor: not distinctive, or faintly sweet. Form: basidiocarps of small to medium size, 5-13 x 1.5-7.5 cm, arising from conspicuous white myeclial strands. Base 1.5-6 x 2-6 cm, single, or if compound, component axes connate giving the appearance of a single stipe, cylindrical, conical or bulbous, basally a white tomentum present, on the upper base small abortive or primordial branches sometimes diverging; mature specimens branching up to 5 times from the base, mostly dichotomous, axils, acute, turbinate, or mostly u-shaped, branches nondivergent to moderately divergent, at maturity mostly subparallel, internodes lengthening up to 3 cm, lower branches sometimes laterally connate, 0.5-1.5 cm in diam, upper branches usually slender, mostly 2-5 mm diam, bifid or antlered and slightly divaricate near the apices; apices subacute, rounded or blunt. Consistency: base fleshy-spongy and branches pliable when fresh, drying hard at the base, and brittle, slightly chalky-friable in the branches.
Macrochemical Reactions: Context of stipe non-amyloid; positive color changes occurring within 30 min of application to branch sections of pyrogallol, a-napthol, guaiac, guaiacol, phenol and aniline; the application of ferric sulphate and guaiac giving immediate reactions.
Microscopic structures: Spores: average 11.5 x 4.6 µm, range 9-14 x 3.5-6 µm, ellipsoid, the apiculus usually prominent. up to 2 x 1.5 µm, ornamented with distinct cyanophilous warts, spores in-deposit "golden yellow" (5B5-7). Hymenium: basidia clavate, 48-80 x 7-11) µm soon collapsing. after spore discharge, containing numerous cyanophilous granules, clamped, l-4-sterigmate, mostly 4; sterigmata 5-10 µm long, frequently 2 µm wide near attachment to basidium, commonly straight and not divergent but sometimes incurved or divergent; hymenium and subhymenium combined 50-70 µm thick. Subhymenial hyphae: interwoven, 2.5-3.5 µm diam, clamped, thin-walled. Mycelial strands monomitic, hyphae 2-4 µm diam, ampulliform swellings near septa up to 12 µm diam, walls smooth. Contextual hyphae: interwoven in the stipe, parallel in the branches, mostly non-inflated, 2-12 µm diam, thin-walled 0.3 µm, walls smooth, strongly cyanophilous; clamps present, closed or open, clamp cells sometimes inflated; gleoplerous hyphae rare, mostly 2.5-3 µm diam.
Discussion: Ramaria testaceoflava var. brunnea is an attractive variety, recognized by the following combination of characteristics: (1) yellow to brown branches, (2) bruising on handling, (3) subparallel, pencil-like mature branches, (4) clamped hyphae, (5) spore morphology, (6) cyanogranular basidial protoplasm, and (7) positive macrochemical reactions with pyrogallol, «-napthol, guaiac, and guaiacol. There is a substantial range of minor variations in size, form, and color of fruiting body and in spore dimensions, but the variety remains distinctive and coherent, fairly easy to recognize in the field. It is most apt to be mistaken for over-mature, discolored fruiting bodies of R. gelatinoua var. oregonensis. Both may have a spongy base, but the base of var. brunnea is not gelatinous. 4[e regard
R. testaceoflava var. brunnea as belonging to the R. formosa alliance (Doty, 1944; Corner, 1950), but also as exhibiting some tendencies toward the R. stricta alliance. The original description of C. brunnea Zeller (1935) pertains to entirely mature specimens as indicated by fruiting body size, form, and color. Tile "Mize yellow" and "golden yellow" colors of our specimens are those of young to partly mature fruiting bodies. The spore measurements of the type, given by Zeller as 8-10 x 4-5 µm, were later changed by Doty C19441 to 10.5-13 x 4.5-5 µm which closely match our measurements.
The principal difference between var. brunnea and var. testaceoflava appears to be size. Fruiting bodies of var. testaceoflava are small, 3-5 cm high, whereas those of var. brunnea are small to medium sized, 5-13 x 1.5-7.5 cm. Except for size, the painting of C. testaceoflava (Bresadola, 1932: 1090), and the descriptions of this species (Bresadola, 1884; Corner, 1950) reflect characteristics similar to those of R. brunnea. Examination of two collections, made and determined as C. testaceoflava by G. Bresadola (NCU), convinces us that R. brunnea (Zeller) Corner should be regarded as a variety of R. testaceoflava (Bres.) Corner. Both species have: (1) clamped hyphae, (2j basidia filled with cyanogranular protoplasm, and (3) identical spore morphology.
