Fruiting body: 4-9cm x 0.5-1.1(2.5)cm, cylindric to subventricose [somewhat wider in middle] or subclavate [somewhat club-shaped], sometimes flattened, obtuse; pallid flesh color then light cinnamon to dark ochraceous flesh color or brownish orange; spore-bearing surface becoming rugulose [finely wrinkled], (Corner), up to 10.5cm tall, 0.6-1.2cm wide at base, widening upward to 2cm, simple, nearly cylindric, clavate, top obtuse or broadly rounded, often irregularly so; at first gray-red, dull red fading to salmon, gray-orange, slowly pale brown to brown when bruised; smooth becoming longitudinally wrinkled, top smooth, (Castellano), up to 10.5cm high, 0.6-1.2cm wide at base, widening upward to 2cm wide, simple, subcylindric, clavate or broadly clavate, apex obtuse or broadly rounded, often irregularly so; at first ''greyish red'', ''dull red'' or ''aurora'', "rose doree", "old rose", "light jasper red", "jasper red" or "eugenia red", then fading to ''salmon color'', ''greyish orange'' or ''peach color, "flesh color", "salmon color", "salmon-buff", "flesh ocher" or "apricot buff", (apex more or less concolorous), when cut or bruised staining slowly irregularly the same color as the flesh stains, more conspicuously downward; smooth, becoming longitudinally rugose to rugulose [wrinkled to finely wrinkled], apex smooth, (Methven)
Flesh: white, slowly somewhat vinescent, (Corner), at first solid, becoming soft and spongy near top; white to pallid, staining slowly irregularly pale brown or brown on exposure, (Castellano), initially solid, becoming soft and spongy upward as the apex enlarges; white to pallid, when exposed staining slowly irregularly ''light brown'' or ''brown'', "Verona brown", "Mikado brown", "russet" or "Mars brown", (Methven)
Stem: base round in cross-section, white to pallid where covered, otherwise ''yellowish white'' to ''orange-white'', "cartridge buff", "pale ochraceous-buff" or "light buff", smooth; mycelial hyphae lacking, (Methven)
Chemical Reactions: KOH stains forest green or yellow green, FeCl3 stains surface forest green to dark green
Odor: negligible (Methven)
Taste: bitter (Methven)
Microscopic: spores 8.5-10.7(12) x 5.6-6.5 microns; basidia 84-112(131) x (7.5)8.5-11 microns; hyphae 3-9.5 microns wide, (Corner), spores 8-10 x 5-6 microns, broadly elliptic, broadly ovate or amygdaliform, smooth, inamyloid, pale yellow in KOH, thin-walled; basidia (2-)4-spored, 60-95 x 8-11 microns, clavate, clamped, sterigmata 6-9.5 microns long; leptocystidia scattered and scarcely projecting, 30-65 x 2.5-5 microns, "cylindric to narrowly clavate, at times apically or subapically branched", walls thin and smooth, contents amorphous, pale yellow in KOH, clamp connections uninflated; hymenium extending over the apex of the fruitbody; subhymenium rudimentary; hyphae of trama 3-12 microns wide, "more or less parallel to longitudinally interwoven basally, more loosely interwoven upward, radially interwoven beneath the subhymenium, uninflated or inflated (-16 microns), branched", walls thin or irregularly thickened to 1 micron wide, smooth, contents amorphous, pale yellow in KOH, clamp connections uninflated or inflated (-12 microns), sometimes medallion or ampulliform; gloeoplerous hyphae 2.5-8 microns wide, "arising from generative hyphae at clamp connections, scattered throughout the trama, more abundant downward, uninflated, inflated (-12 microns) or strangulated, branched", walls thin and smooth, contents amorphous, pale yellow in KOH, refractive under phase contrast, clamped, (Methven)
Spore Deposit: white (Methven)
Habitat / Range
fasciculate in clusters of 6-20, on well-decayed humus of coniferous woods, (Corner), "Scattered to gregarious; terrestrial; duff; coniferous or mixed deciduous-coniferous forests", (Methven)
