Ciri dan struktur

The new species is distinguished from M. exscissa in having yellowish tinct pileus and without any type of cystidia. Pileus 30–60 mm diam., flat at first, becoming depressed at disc when mature, margin sometimes cracking, surface glabrous, grey to yellowish-grey (4B1 to 4B2), greyish-brown (4B4 to 4B6) at centre, often darker at margin. Lamellae crowded, adnate to decurrent, white to yellowish-white (4A2), 2.5–3.0 mm broad, with lamellulae, edge entire. Stipe cylindrical, 20–35 mm long × 2–5 mm diam., central, broadened at base, solid, surface grey to yellowish-grey at first (4B1 to 4B2), becoming yellowish-brown (5D8, 5E8) with age or after touching, striate, often with whitish basal tomentum. Pileus context up to 10 mm thick near stipe attachment, thin at margin, yellowish-grey (4B2), grayish brown to yellowish brown (5D3 to 5E5) in stipe cortex, up to brown (6E7) in stipe base. Odour none, taste mild. Spore print white. Basidiospores (90/6/2) 7.0–8.5 (9.0) × 4.0–6.2(6.5) μm, av. 7.5 × 5.2 μm, Q = 1.40–1.45(1.50), ellipsoid, hyaline, amyloid, ornamentation verruculose, with irregular warts, sometimes with ridges. Basidia (20) 23–29 (30) × (7.0) 7.5–9.0 (10.0) μm, av. 26 × 8.5 μm, clavate, 4-spored, sometimes 2-spored, subhyaline. Hymenial cystidia absent, lamella edge sterile. Hymenophoral trama 42–85 μm broad, regular with thin-walled hyphae 5.5–16.5 μm diam., hyphae not pigmented. Subhymenium poorly developed. Pileipellis a cutis of numerous repent branched hyphae, 5.5–7.5 μm wide, thin-walled. Stipitipellis hyphae 3.5–8.0 μm diam., thin-walled, hyaline. Caulocystidia absent.
