Description:Pileus 25-88 mm diam., at first hemispherical when young, becoming plano-convex to convex with a depressed centre, viscid or glutinous when moist, peeling up to ½ of radius in mature sample, reddish golden brownish orange to caramel (6C5-6) or pompeian yellow (5C6) to honey yellow or oak brown (5D6), center slightly darker or in combination with english red or venetian red (8D8) sometimes; margin decurved to plane when mature, obscurely or faintly striate. Lamellae adnexed, subdistant to rather close (6-8/cm at pileus margin) after maturity, forked near stipe apex or middle, yellowish white (3A2), unchanging on bruising; edge entire, marginate reddish; lamellulae rare. Stipe 30-75 × 10-25 mm, cylindric to subclavate, surface dry, longitudinally venose, most completely pastel red (8A4) with chalky white (1-2A1) patches at base, unchanging when bruised but. Context solid to stuffed in stipe with age, chalky white (1-2A1), turning salmon (6A4) with FeSO4 and orange red or high red or vivid red (8-9B8) with guaiacol. Taste indistinctive. Odor indistinctive. Spore print yellowish white (3A2). Basidiospores 8.21-9.49-10.37 × 6.96-7.99-9.14 μm, (n = 30, Q = 1.06-1.17-1.28), usually subglobose to broadly ellipsoid; ornamentation partially amyloid, up to 2 μm high, composed of cylindrical (mostly with rounded apices) isolated very high to low warts, occasionally laterally fused; suprahilar plage amyloid. Basidia 32-46 × 10-13 μm, subclavate, 2- or 4-spored; mature sterigmata 7-10 × 2-2.5 μm. Subhymenium 20-35 μm thick, made up of pseudoparenchymatous cells. Pleurocystidia common, 66.4-72.5 × 9.2-11.3 μm, emergent 3.8–19 μm; elongated ventricose, with fusoid to subfusoid apices, thin-walled, content dense, somewhat granulose. Cheilocystidia 33-45 × 7–9 μm, emergent 7-12 μm, narrow clavate to narrow ventricose, with subfusoid, rounded to appendiculated apices, thin-walled, content dense. Hymenophoral trama composed of numerous sphaerocytes and connecting hyphae; Pileipellis up to 125 μm thick, composed of abundant suberect cystidia and septate hyphae; pilear hyphae 3.6-4.2 μm; terminal cells cylindric with rounded apex, wide, septate, branched; pileocystidia 4.5-5.8 μm cylindric to narrowly subclavate with rounded apices. Stipetipellis up to 87 μm thick, composed of parallel to subparallel hyphae and cystidia with erect tips. Clamp connections absent in all tissues.
