Brief Description: [See More | Edit]

FRUIT BODY 7–15 cm across, 7–13 cm tall, stipe typically very stout, branches compact, lower branches often thick, with short upper sections. Tips yellow, light orange, pinkish, or with red tinges. Branches pallid orange, with tinges of pale red, occasionally with violet-gray bruises. STIPE 2–6.5 cm long, 2–4 cm thick, stout, stocky, equal or tapering towards base. Whitish to cream when young, developing brown stains, to mostly brown in age. FLESH fibrous to stringy, reddish to orangish white in branches, whitish in stipe, with brownish bands, brown from base up. ODOR indistinct to slightly sweet. TASTE indistinct. CHEMICAL REACTIONS: Flesh quickly amyloid (turning violet-brown in Melzer’s reagent); turquoise green in FeSO4. SPORE DEPOSIT apricot yellow. MICROSCOPY: Spores 7–10 x 3–4 μm, averaging 8.9 × 3.6 μm, narrowly cylindrical, nearly smooth, or with weak ornamentation. Basidia with basal clamps.
ECOLOGY: Ectomycorrhizal with conifers, especially fir (Abies spp.), Western Hemlock (Tsuga heterophylla), and Douglas-fir (Pseudotsuga menziesii). Likely re- stricted to old-growth stands. Solitary or scattered on the ground, fruiting in fall.
SIMILAR SPECIES: Ramaria celerivirescens has salmon-colored branches, and typi- cally, brighter yellow tips when young (although soon becoming the same color as R. amyloidea). It can be distinguished by its weakly amyloid flesh, lack of clamps on the basidia, and distinctly warted spores. Ramaria velocimutans is white or cream to yellowish in color, with brownish stains on the stipe, and with brown flesh in the stipe. It is easily distinguished from R. amyloidea by its inamyloid flesh and finely warted spores. Ramaria rasilispora and R. magnipes are yellow, lack the brown flesh in the stipe, and have larger spores. Ramaria maculatipes can also look similar, but soon develops wine-red stains on the stipe.
