03C297756475FFB6FF36FF31FEF36A01.taxon	materials_examined	Holotype: — PAKISTAN. Punjab, Sheikhupura, on muddy soil of graveyard, (31 ° 43 ’ 3.71 ” N, 73 ° 57 ’ 19.73 ” E), 236 m a. s. l., 18 August 2018, Aiman Izhar, Skp 003 (LAH 36654). Diagnosis: — Pileus brown to yellow, hygrophanous. Stipe central to slightly eccentric. Basidiospores 8.7 – 10 × 4.9 – 6.3 μm, ellipsoid-amygdaliform, almost smooth to finely verruculose. Cheilocystidia clavate to subcylindric. Pleurocystidia absent. Both pileipellis and the stipitipellis a trichoderm with many cystidia. Clamp connections present. Etymology: — In honor of Prof. Dr. S. H. Iqbal (Late) Mycologist, for his contributions to fungal taxonomy in Pakistan. Gene sequence ex-holotype: — GenBank MT 97348 (ITS) and MW 888515 (LSU). Description: — Pileus 15 – 30 mm diam, reniform when seen from above, hemispherical to convex, a few almost circular, some later becoming flabelliform, bright brown (7.5 YR 5 / 6) when immature, pale yellow (5 Y 8 / 4) to yellow (10 YR 8 / 8) at maturity, umbilicate at disc with dull brown color (7.5 YR 5 / 4), flabby, hygrophanous, surface smooth to velvety, minutely tomentose near disc, margin straight, later inflexed, tuberculate-striate to rimose. Lamellae 2 – 4 mm broad, adnate, some emarginate with a decurrent tooth, yellow (10 YR 8 / 8) when young, later fading to pale yellow (5 Y 8 / 4), moderately crowded, furcate, edges entire to undulate. Stipe 10 – 17 × 3 – 6 mm, central to slightly eccentric, cylindrical, forked near the cap, base broad, pale yellow (5 Y 8 / 4) near pileus, white to dull orange (7.6 YR 6 / 4) towards base, turning dark brown (10 YR 3 / 4) on handling, rubbery, hollow, minutely pruinose, mycelial pad at base. Annulus absent. Odor not characteristic. Taste not checked. Basidiospores 8.7 – 10 × 4.9 – 6.3 μm, Lm × Wm = 9.6 ± 0.7 × 5.4 ± 0.4 μm, Q = 1.7 – 1.6 μm, avQ = 1.8, ellipsoidamygdaliform, almost smooth to very finely verruculose, thick-walled, with a large and many little brownish gray (10 YR 6 / 1) guttules. Basidia 22 – 34 × 7 – 9 μm, cylindrical to clavate, clamped, mostly 4 - spored, few 2 - spored, hyaline, thin-walled, granulate, a few large oil drops present. Cheilocystidia 14 – 28 × 3.6 – 6.8 μm, mostly clavate or flexuous less cylindric, mostly often septate, clamped. Pleurocystidia absent. Pileipellis a trichoderm, with hyaline, cylindrical hyphae, 4 – 8 μm, avw = 6 μm, septate, branched, gelatinization present in some of the hyphae, frequently clamped, terminal cells cylindrical or clavate (5 – 9 μm), occasionally branched. Pileocystidia 19.8 – 38 × 6.3 – 7.8 μm, clavate to cylindrical, at times narrowly clavate, lageniform, narrowly utriform, mostly flexuous, clamped. Stipitipellis an intricate trichoderm, with interwoven hyphae 7 – 5 μm (avw = 4.1 μm), thin to slightly thick-walled, hyaline, septate, some hyphae with gelatinization terminal cells cylindric, clamped. Caulocystidia 10 – 17 × 3.8 – 7.6 μm, mostly lageniform to utriform, few lecythiform, clavate, flexuous, grouped, basal cells slightly inflated, hyaline, clamped. Habitat and distribution: — Pleurotoid, solitary, on muddy soil of a burial ground which adjoins a church, under Ficus benghalensis. Additional material examined: — PAKISTAN.
