Gyroporus alpinus

Ciri dan struktur

This species differs from other cyanescent species of Gyroporus in its initially ivory yellow to greyish-yellow and then grey-orange to brownish-yellow pileus, scaly to floccose pileal surface, distribution in alpine forests with altitude up to 3800 m, broad basidiospores (5.5–8.5 µm wide) and long and slender basidia measuring 35–55 × 7–12 µm. Pileus 3–6 cm in diam., sub-hemispherical to convex or plano-convex, ivory yellow (4B3) to greyish-yellow (2B3–4) when young, grey-orange (5B5) to brownish-yellow (5C6–7) when mature; surface dry, densely covered with concolorous appressed scaly to floccose squamules, margin always incurved and slightly extended; context whitish (1A1), staining cerulean blue (23C6–7) to dull blue (23E5–6) when bruised. Hymenophore adnate when young, slightly depressed around apex of stipe when mature; surface white (1A1) when young and then cream to yellowish when mature, staining dull blue (23E5–6) when bruised; pores angular to roundish, fine, 2–3 per mm; tubes 3–8 mm long, whitish (1A1), staining dull blue when bruised. Stipe 6–8 × 1.8–2 cm, sub-cylindrical to clavate, white (2A1) when young, yellowish-white (2A2) to concolorous with pileal surface when mature; surface roughened, staining dull blue when bruised; context white to cream or yellowish, spongy when young and then hollow in age, staining cerulean blue to dull blue when bruised. Odour indistinct and taste mild. Basidia 35–55 × 7–12 µm, clavate, 4-spored, hyaline in potassium hydroxide (KOH) and yellowish in Melzer’s Reagent. Basidiospores [60/3/2] (6.5) 7–10 × 5.5–7.5 (8.5) µm, [Q = 1–1.65 (1.72), Q m = 1.27 ± 0.23], smooth, ellipsoid to somewhat broadly ellipsoid, yellowish in KOH and primrose yellow in Melzer’s Reagent.
