Diagnosis: — differing from Melanoleuca cinereifolia (Bon) Bon in having white lamellae, small ellipsoid basidiospores, similar cheilocystidia and pleurocystidia without crystals, and a cutis type pileipellis. Holotype: — PAKISTAN. Khyber Pakhtunkhwa province: Dir Upper district, Kumrat Valley, 2401 m asl, growing on rich loamy soil near Panjkora river, 2 September 2015, Abdul Nasir Khalid and Farzana Nawaz FS 107 (LAH 35159!; GenBank KU 575243). Description: — Basidiomata tricholomatoid, medium. Pileus 42 – 57 mm diam., convex, obtusely umbonate, margin straight, smooth, glabrous, dry; occasionally cracked, light pink (5 P 9 / 4) to yellowish (5 Y 8 / 4) becoming grey (7.5 Y 6 / 2) to greenish (7.5 Y 6 / 4) or dark grey (7.5 Y 3 / 2).

Cheilocystidia 42.9 – 84 × 8.9 – 19.7 μm, [avl × avw = 65 × 13.4 µm], fusoid-ventricose, leptocystidia. Pleurocystidia similar to cheilocystidia. Pileipellis a cutis of cylindrical hyphae 6.8 – 16.8 μm in diameter (av = 11 µm), thin-walled, septate, branched, hyaline. Stipitipellis composed of cylindrical hyphae 4.7 – 17.2 μm in diam.
