Basidiomata ( Fig. 2a–d View FIGURE 2 ) very small to large. Pileus 1–12 cm, convex to applanate with low umbo to slightly concave, glutinous when wet, grayish brown, yellowish brown, light brown, brown to blackish brown (5F6–5F 8, 6E 5–6E7, 6F3–6F8) over disc or when immature, smooth with nearly black “veins” radiating from the disc onto or over the limb, sometimes with reticulate “veins” near the margin; Context white to dirty white, unchanging in color when cut. Lamellae adnate to sinuate or slightly decurrent, subdistant, with lamellulae, thick, white to cream; lamellar edge white. Stipe 2–30 × 0.2–2.1 cm, subcylindrical, enlarged at ground line, surface dirty white to grayish, densely covered with brownish felted squamules but nearly white at apex; pseudorhiza dirty white. Taste mild to somewhat sour; odor indistinct. Spore print white to cream.
Lamellar trama ± regular, composed of branching, nearly colorless and hyaline, slightly thick-walled (≤ 1 μm thick), filamentous to inflated hyphae 3–25 μm wide. Basidia ( Fig. 3d View FIGURE 3 ; Fig. 4d View FIGURE 4 ) 34–80 × 9–20 μm, 2-spored or 4- spored, thin-walled, colorless hyaline, without any siderophilous granulation; sterigmata up to 12 μm in length. Spores ( Fig. 3c View FIGURE 3 ; Fig. 4c View FIGURE 4 ) [240/12/11] (13) 14–18 (21) × (9) 10–13 (16) μm, Q = (1.06) 1.20–1.50 (1.64), Q = 1.30 ± 0.09, ellipsoid, ovoid to sublimoniform, thin-walled, colorless and hyaline, non-amyloid, non-dextrinoid. Pleurocystidia ( Figs. 3e View FIGURE 3 , 4e View FIGURE 4 ) 70–200 × 17–52 μm, pedicellate, fusiforms with prominent capitate apex, sometimes incrusted brownish to golden substances, thin-walled to slightly thick-walled, colorless and hyaline. Cheilocystidia ( Figs. 3b View FIGURE 3 , 4b View FIGURE 4 ) 25–240 × 5–41 μm, crowded and numerous, pedicellate, fusiform, narrowly clavate, subcylindrical to cylindrical, thin-walled, colorless and hyaline. Pileipellis ( Figs. 3a View FIGURE 3 , 4a View FIGURE 4 ) an ixohymeniderm of 120–190 μm thick, composed of clavate, broadly clavate to sphaeropedunculate, brownish to brown intracellularly pigmented cells (18–80 × 10–47 μm) embedded in a gelatinized matrix. Pileocystidia ( Figs. 3a View FIGURE 3 , 4a View FIGURE 4 ) abundant, subcylindrical to narrowly fusiform, 70–190 × 3–12 μm, thin-walled, nearly colorless or with brownish to brown intracellular pigment; apex acute or narrowly rounded. Stipitipellis composed of vertically arranged, branching, slightly yellow to slight brown, hyaline, slightly thick-walled (ca. 0.5 μm thick), filamentous hyphae 3–25 μm broad. Caulocystidia ( Figs. 3f View FIGURE 3 , 4f View FIGURE 4 ) 45–250 × 8–22 μm, numerous and crowded, caespitose, narrowly clavate to subcylindrical, thin- to slightly thick-walled (ca. 0.5 μm thick), with grayish brown to yellowish brown intracellular pigment, occasionally nearly colorless and hyaline. Clamp connections abundant in every part of 4-spored basidioma, but absent in 2-spored basidioma.
