Retiboletus ater

Ciri dan struktur

Basidiomata small to medium-sized. Pileus 3–5 cm in diameter, hemispherical to applanate, surface dry, densely subtomentose, black (4F3) to blackish (4E2) in the center and gray (3D1) or yellowish-gray (3C2-3) towards margin, context 2.5 cm thick in the center of the pileus, pallid gray (2D1) to cream (2C3-4), unchanging when bruised. Hymenophore adnate or slightly depressed around apex of stipe; pores angular, tubes up to 11 mm long, 0.3–1 mm wide, white (2B1) when young and yellowish (2A2) in age, becoming brownish-yellow (5C7-8) when injured. Stipe 4–6 × 0.8–1.2 cm, clavate to flexuous, solid; surface dry, blackish to gray, prominently and coarsely reticulate over the upper 1/3; context white (2A1) in the upper part and yellowish to cream yellow downwards, unchanging when injured; basal mycelium white (2A1). Taste and odor indistinct. Basidia 26–38 × 6–10 μm, clavate, thin-walled, 4-spored, hyaline to yellowish in KOH. Basidiospores [60/3/2] (7)8–10.5(11) × 3–4.5(5) μm [Q = (1.89) 2–3.33 (3.67), Q m = 2.52 ± 0.42], subfusiform and inequilateral in side view with shallow suprahilar depression, elongate fusoid or narrowly oblong in ventral view, slightly thick-walled (up to 0.5 μm), brownish to yellowish-brown in KOH, olive-brown to brown in Melzer’s reagent, smooth. Hymenophoral trama boletoid; hyphae cylindrical, 3.5–9 μm wide, hyaline to yellowish in KOH, yellowish to brownish-yellow in Melzer’s reagent. Cheilo- and pleurocystidia 26–55 × 6–10 μm, abundant, subfusiform to fusiform, thin-walled, with yellowish-brown contents, surface without encrustations. Caulocystidia forming the reticulum over the stipe surface, similar to cheilo- and pleurocystidia.
