Boletopsis macrocarpa

Ciri dan struktur

Basidiomata annual, medium to large, centrally stipitate, solitary to gregarious (Fig. 1 d, e). Pileus 6.5–21 cm in diameter, roundish to irregular, slightly depressed at centre, cream (5A2) to greyish-brown (5E6), becoming pale brownish-grey (5D3) to black when dry; margin occasionally cream, undulate. Context white (1A1), becoming pale mouse-grey (2B/C2) when dry. Hymenophore slightly decurrent; surface white (1A1) to cream (5A2), becoming clay buff (6D4) to fawn (7D/E4) when dry, pores subangular to angular or irregular, 1–3 per mm; tubes concolorous with hymenophoral surface, turning fawn (6D7) when bruised, up to 0.5 cm long. Stipe up to 8.5 cm long and 5.5 cm wide, solid, subcylindrical, pale ash-grey (17B1) or concolorous with pileal surface. Hyphal system monomitic. Generative hyphae with clamp connections. Basidia thin-walled, 18–45 × 5.5–10 μm, clavate to cylindrical, sometimes flexuous or ventricose with a peduncle, 4-spored, clamped at base, hyaline in KOH (Fig. 4 a). Basidiospores [60/3/3] (4.5) 5–6 × (3.5) 4–5 (5.5) μm, Q = 1–1.38 (1.5), Q m = 1.20 ± 0.13, globose to oblong, acyanophilic and non-dextrinoid, hyaline to pale yellow in KOH; ornamentation on the surface tuberculate and sometimes furcate (Fig. 3 c, d; Fig. 4 b). Cystidia absent. Tube tramal hyphae thin-walled, 2–4 μm wide, cylindrical, interwoven and occasionally subparallel in a bunch, hyaline in KOH. Hyphae of pileipellis thin-walled, 3–9 μm wide, cylindrical, interwoven and occasionally subparallel, hyaline to faint olivaceous in KOH; terminal cells 22–53 (56) × (3) 4–7 (9) μm (Fig. 4 c). Pileal tramal hyphae thin-walled, 4–44 μm wide, inflated, sometimes branched, interwoven, hyaline in KOH.
