Brief Description: [See More | Edit]

FRUIT BODY 2–8 cm across, 8–10 cm tall, base simple to nearly compound, branches typically slender, compact at first, becoming rather upright. Tips dark orange, fading slightly with age. Branches pale orange to orange-yellow, with a yellow band around the lower branches and upper stipe. STIPE 1–4 cm long, 1–2 cm thick, short to slightly rooted. Base white, upper portion with a yellow band, occasionally with caramel-brown stains. FLESH fleshy-fibrous, (not gelatinous), whitish in stipe, branches orangish, tips bight orange. ODOR indistinct to slightly sweet. TASTE indistinct. CHEMICAL REACTION: Flesh inamyloid. SPORE DEPOSIT scant, unknown color. MICROSCOPY: Spores 8.5–14 x 3–5 μm, averaging 10.8 × 4 μm, cylindrical to nearly tear-drop shaped, ornamented with fine warts. Basidia lacking basal clamps.
ECOLOGY: Solitary or scattered on ground; ectomycorrhizal with conifers; espe- cially fir (Abies spp.), Western Hemlock (Tsuga heterophylla), and Douglas-fir (Pseudotsuga menziesii). Fruiting in fall.
SIMILAR SPECIES: Ramaria gelatiniaurantia also has orange tips and branches, and a yellow band at the stipe apex, but has distinctly gelatinous flesh. Ramaria san- daracina is typically more brightly colored with bright orange to orange-yellow tips, orange upper branches, and a bright yellow band on the lower branches. It has fibrous-fleshy or slightly gelatinous flesh, shorter (8 μm) papillate-warted spores, and has clamp connections. Ramaria flavigelatinosa has bright yellow tips, yellow branches, and firm gelatinous flesh. Ramaria armeniaca is a spring fruiting species with bright orange tips, apricot-colored branches, and occasionally shows a pale-yellow band on the lower branches and upper stipe. It can easily be distin- guished from R. aurantiisiccescens by its vernal fruiting, and slightly shorter, nearly smooth spores.
