Ciri dan struktur
The new species is distinguished from M. exscissa in having adnexed to adnate lamellae and fusiform cheilocystidia. Pileus 35–60 mm diam., flat at first, then gradually depressed, margin slightly inflexed when mature, surface fibrillose, greyish-brown (4B3 to 4B5), becoming deep yellow (4C6 to 4C8) at centre. Lamellae crowded, adnexed to adnate, white, 2.5–3.0 mm broad, with lamellulae, edge entire. Stipe cylindrical, 30–50 mm long × 3–5 mm diam., central, somewhat broadened at the base, fibrous, expanded at base, solid, surface yellowish-grey to greyish at first (4B2 to 4C2), becoming yellowish-brown (5E7 to 5E8) with age, striate, with whitish basal tomentum. Pileus context up to 10 mm thick near stipe attachment, thin at margin, greyish-yellow to yellowish-grey (4B4 to 4B2), yellowish-grey (4B2) in stipe cortex, whitish in stipe base. Odour none, taste mild. Spore deposit white. Basidiospores (234/10/8) (5.0) 6.0–7.2 (8.0) × 4.0–5.0 (6.0) μm, av. 6.5 × 4.5 μm, Q = (1.30)1.45–1.55 (1.60), ellipsoid, hyaline, amyloid, ornamentation verruculose, warts with ridges, almost reticulate. Basidia (18) 20–25 (28) × (4.0) 5.0–6.5 (7.0) μm, av. 22 × 6.0 μm, clavate, 4-spored, occasionally 2-spored, hyaline. Cheilocystidia (40) 45–55 (60) × (6.0) 8.0–12.0 (15.0) μm, fusiform, thin-walled, with encrusted crystals at apex, abundance. Pleurocystidia scattered, similar to cheilocystidia. Hymenophoral trama 90–150 μm broad, regular with thin-walled hyphae 3.0–14.0 μm diam., hyphae not pigmented, lamella edge sterile, Subhymenium poorly developed. Pileipellis a cutis of numerous repent branched hyphae 7.5–10.5 μm wide, thin-walled, pigmented with light violet.
