Pileus 30 – 50 mm diam., hemispherical to spherical, broadly parabolic when young, becoming wider towards maturity, sometimes cracked or rimose upon maturity; margin initially decurved, becoming straight upon maturity; surface smooth, bright brown (7.5 YR 5 / 8) at center, becoming lighter yellow-orange (2.5 Y 8 / 4) in patches towards margin. Lamellae adnate to sinuate, regular, ventricose to broadly ventricose, subdistant to close, with entire edges; pale yellow (5 Y 8 / 4) when young, becoming concolorous with the pileus with age. Lamellulae wavy, numerous, variable in length, alternating with lamellae. Stipe 30 – 50 mm long, central, solid, narrower at the apex, gradually becoming broader towards the base, slightly fibrillose, concolorous with the pileus. Annulus absent. Context of pileus and stipe pale yellow (2.5 Y 8 / 4). Taste not checked. Odor unpleasant. No color reaction of the pileus to alkali was detected. Basidiospores [40 / 2 / 2], (10.0 –) 10.95 – 12.04 (– 12.87) × (6.0 –) 6.78 – 7.13 (– 7.89) µm, (avL × avW = 11.45 × 6.96 µm), Q = 1.7, oblong to ellipsoid, guttulate, apiculate, smooth, thin-walled, reddish brown in KOH, inamyloid. Basidia 35.2 – 52.5 × 8.8 – 11.4 µm, clavate to sub-clavate, two to four sterigmate, thin-walled, hyaline to light green (5 G 9 / 2) necropigment, hyaline in 5 % KOH. Pleurocystidia absent. Cheilocystidia 16.6 – 20 × 4 – 7 µm, narrowly utriform to utriform, rare, hyaline in 5 % KOH. Pileipellis a cutis, hyphae 7.2 – 9.8 µm, cylindrical, intertwined, broader toward pileal apex, narrower in the mat, hyaline in 5 % KOH. Stipitipellis a cutis, with hyphae 5.4 – 9.9 µm in diam, branched, parallel, septate, and hyaline in KOH. Clamp connections present in all tissues.	en	Kiran, Munazza, Sana, Sattar, Ammara, Khalid, Abdul Nasir (2025): A new species and a new record of Mallocybe (Inocybaceae, Agaricales) from Pakistan uncovered by integrated morphology and phylogeny.
