Conocybe kotadduensis Haqnawaz, Niazi & Khalid sp. nov. Figs 3, 4 Etymology. Species name “ kotadduensis ” (Latin) refers to the type locality Kot Addu, Punjab, Pakistan. Holotype. Pakistan • Punjab, Kot Addu District, bed of Indus River, (30°23'27"N, 70°48'28"E, 127 m a. s. l.), on plant debris, June 14, 2023, Muhammad. Haqnawaz, KA- 06 (LAH 38248). GenBank: PQ 409233 (nrITS), PQ 409236 (nrLSU). Diagnosis. Conocybe kotadduensis is different from the closest species, C. nitrophila, by its relatively light gray to pale yellow, parabolic absence of thick glutinous veil and viscid in regular to slightly crenate margins of pileus, adnexed, broad, thick lamellae with 2–3 tires of lamellulae, scabrous surface of stipe, amygdaliform to ovoid basidiospores, mostly broad bi-sterigmate of basidia, clavate, utriform with median constriction, fusiform, cylindrical shape of lecythiform cheilocystidia, sphero-pedunculate to obovoid, globose to sub-globose pileipellis elements. Description. Pileus 10–13 mm diam., hemispherical to parabolic at young stage, conical, parabolic when old, straight shape of margins, regular to slightly crenate cap margins, velutinous surface, light gray (7.5 YR 8 / 1) to pale yellow (2.5 Y 8 / 4), with dull yellow orange (10 YR 7 / 4) center. Lamellae adnexed, broad, thick, subdistant, fimbriate, unequal, with exceeding 1–3 tires, dull yellow orange (10 YR 7 / 4) to orange (7.5 YR 7 / 6). Stipe 25–49 mm in length, cylindrical, flexuous, central, with slightly scabrous surface, hard and dry, slightly broad toward base, orange (5 Y. R 6 / 6) at upper side, dull yellow orange (10 YR 7 / 4) at base, grayish white (N 8 / 0). Basidiospores [100 / 2 / 3], (13.2 –) 13.5–15.5 (– 16) × (8 –) 8.5–9.5 (– 10) µm, avl × avw = 14.7 × 9.0 µm, Q = 1.47–1.69, Q av = 1.62, amygdaliform to ovoid, yellowish to slightly light brown in 5 % KOH, thin walled, guttulate, prominent germ pore. Basidia [30 / 2 / 3] (24 –) 24–28 (– 29) × (10.5 –) 11–11 (– 11.5) µm, clavate, with 2 sterigmata with broad width, hyaline in 5 % KOH, thin-walled. Cheilocystidia [30 / 3 / 3] (14 –) 14.5–24 (– 24.5) × (5.5 –) 6. – 10.5 (– 11) µm, lecythiform with clavate, utriform with median constriction, fusiform, cylindrical shap of cells, rarely lageniform, hyaline, thin walled. Pileipellis [30 / 2 / 3] (25–89 × 1637 µm, sphero-pedunculate to obovoid, globose to sub-globose, hyaline and thin walled. Stipitipellis 8–23 µm, avw = 9.8 µm, cutis, hyaline in 5 % KOH, thin walled, septate, unbranched, regular. Caulocystidia [15 / 3 / 3] 9–14 × 5–7 µm, rarely present, clavate to cylindrical, hyaline in 5 % KOH, thin walled. Clamp connection absent. Ecology and habitat. Gregarious, terrestrial, under plants of Saccharum bengalense and Cyperus rotundus. Additional specimens examined.
