Retiboletus sinogriseus

Ciri dan struktur

Basidiomata medium-sized. Pileus 6–7.2 cm in diameter, subhemispherical to applanate, sometimes convex; surface tomentose, grayish-brown (5D2-3) to brown (5E4), rimose when dry, always cracked into small squamules on grayish (4B1) to whitish (2A1) background; context 1–2 cm thick in the center of pileus, white (1A1), unchanging when injured. Hymenophore adnate, sometimes slightly depressed around apex of stipe; pores angular, 0.3–1 mm wide, tubes up to 14 mm long, yellow (4C3-4) to grayish-yellow (4B2-3), unchanging when injured. Stipe 6–8 × 1.1–1.5 cm, subcylindrical, solid; surface dry, pale yellow at apex, blackish-yellow towards the base, entirely covered with moderately developed reticulum; context white to cream in the upper part and yellowish to yellow downwards, unchanging when injured; basal mycelium yellow. Taste and odor indistinct. Basidia 21–27 × 9–11 μm, clavate, thin-walled, four-spored; sterigmata 4–5 μm long. Basidiospores [40/2/2] (9) 10.0–13.5 (–14.0) × (3) 4.0–5.0 (–5.5) μm, Q = (2.25–) 2.5–3.25 (–3.42), Q m = 2.88 ± 0.32, subfusiform to ellipsoid, slightly thick-walled (up to 0.5 μm), hyaline to yellowish in KOH, olive-brown to yellowish-brown in Melzer’s reagent, smooth. Hymenophoral trama boletoid. Cheilo- and pleurocystidia 35–56 × 7–12 μm, abundant, subfusiform to fusiform, thin-walled, with yellowish-brown to brown contents, without encrustations. Pileipellis a subcutis, 100–120 μm thick, composed of thin-walled filamentous hyphae 4–7 μm wide, with subcylindrical to clavate terminal cells 33–72 × 4–6 μm, sometimes with subacute apex, colorless to pale yellowish-brown in KOH, yellow-brown to brownish in Melzer’s reagent.
