MycoBank no. MB 820540
Etymology:—The specific epithet refers to the gravel coloration of the pileus of the taxon.
Diagnosis:—Pileus grayish brown to off-white towards the margins with non persistent universal veil remnants, slightly umbonate, striated margin, a long ringless stipe bearing a saccate volva with verrucose surface and brownish patches, inamyloid globose to subglobose basidiospores measuring 10–11.5 × 10.5–11 μm, filamentous pileipellis with some inflated round to elongated cells.
Holotype:— PAKISTAN. Khyber Pakhtunkhwa province, Swat district, Mashkun , 2500 m asl, on soil under Cedrus deodara , 5 September 2013, S. Jabeen & A. N. Khalid K4-34 ; SJ44 ( LAH35044 About LAH !; GenBank accessions for ITS: KY781174 ; for LSU: KY781175 )
Description:— Pileus up to 5.3 cm broad, convex to flat at maturity, slightly umbonate, cuticle thin, striate, grayish brown (5YR4/2) from the centre becoming light grey (10Y7/2) or off-white (7.5Y9/2) towards the margins when mature, non persistent off-white (7.5Y9/2) universal veil sometimes present but often disappeared, surface dry, margins slightly incurved sometimes rimose. Lamellae up to 0.3 cm broad, adnexed, sub distant to close, edges entire, off-white (7.5Y9/2); lamellulae common. Stipe 7.7 cm long, 0.5 cm from the apex becoming broad from the middle up to 0.8 cm, up to 1.5 cm, centrally attached, cylindrical, surface dry, granular from the top, becoming smooth towards the base, brown (2.5YR3/4) to off-white (7.5Y9/2), sometimes with grayish scales on the surface, denser towards the base. Volva prominent, up to 1/4 length of the stipe, saccate, membranous, surface verrucose, off-white (7.5Y9/2) bearing yellowish brown patches with age. Annulus absent.
Basidiospores [80/4/4] (10–) 10.1–11.7 (–12) × (9.6) 10.4–11 (–11.5) μm, Q = 1.02–1.08, avQ = 1.08 ± 0.1, inamyloid, globose to subglobose, smooth, thin-walled, hyaline in 5% KOH. Basidia 32–36 × 11.2–14.4 μm, clavate with 2 and 4 sterigmata, hyaline in 5% KOH, clamp connections absent at the base of the basidia. Pileipellis a cutis of filamentous hyphae, 11.3–21.6 μm in diameter, infrequently septate, hyaline in 5% KOH. Stipitipellis made up of filamentous hyphae, 9.3–24.7 μm wide, branched, hyaline in 5% KOH, septa infrequent. Volval hyphae filamentous in the outer layer, 1.8–3.8 μm in diam., and inflated cells below, inflated cells globose to subglobose 31–44 × 33.5–44.5 μm. Volval remnants on pileus same as volva.
