Vanderbylia kashmiriana U. Irfan, Khalid & Aziz sp. nov. ( Figures 3 View FIGURE 3 & 4 View FIGURE 4 )
Mycobank: MB#849986
Etymology: The specific epithet ‘ kashmiriana’ refers to the locality of the collection, Azad Jammu & Kashmir, Pakistan.
Diagnosis: Vanderbylia kashmiriana differs from its closest species V. delavayi in creamy to pale yellow corky pileate basidiocarp with wavy margins, globose to sub-globose to ellipsoid, non-truncate and variably dextrinoid basidiospores (4.2) 5.4–6.7 (6.8) × (2.8) 3.5–5.5 (5.9) µm; with abundant arboriform hyphae; sub-clavate to obovoid basidia and the presence of clavate to obclavate cystidia.
Holotype: PAKISTAN. Azad Jammu & Kashmir, District Bhimber, Tehsil Samahni (33° 3’52.63”N, 74° 5’45.40”E) 826 m a.s.l., at the base of Zanthoxylum armatum DC , October 17, 2022, SM 01 Uzma Irfan (LAH37856), GenBank (OR120349 ITS), (OR120347 LSU) GoogleMaps
Basidiomata perennial, pileate, corky when fresh, becoming hard corky upon drying, single to imbricate, smells like wood, taste not recorded. Pileus 190–210 mm in diameter, sulcate, glabrous, cream to pale yellow (Hue 5 Y 9/2) with wavy margins. Context cottony when fresh, hard upon drying; Pore surface round, concolorous with pileal surface. Basidiospores (4.2) 5.4–6.7 (6.8) × (2.8) 3.5–5.5 (5.9) µm, avL × avW 5.72 × 4.06, Q = 1.5–1.1, Q av = 1.27, globose to subglobose to ellipsoid, hyaline, with apiculus, highly dextrinoid. Basidia 21.3–27.8 × 4.3–5.7 µm, clavate to sub-clavate to obovoid, clamp connections present, hyaline in 5 % KOH; sterigmata 1–4 about 1.9–2.3 µm long, sharp; Cystidia 16.0–40.3 × 3.9–7.3 µm, abundant, polymorphic, clavate to obclavate to ventricose, tubular, apically encrusted, granular throughout, clamp connections present. Plurocystidia and Pileocystidia absent. Dimitic hyphal system in context and tubes, highly dextrinoid, olive green to hyaline (7.5Y 9/2) in 5 % KOH. Contextual hyphal system: Dimitic; Skeletal hyphae 1.2 × 5.0 µm, frequent, thick-walled with narrow lumen, rarely branched, Arboriform hyphae 3.6 × 14.7 µm, extensively branched like a tree with short lateral and terminal processes. Tramal hyphal system generative hyphae not observed. Skeletal hyphae 1.5 × 3.9 µm, frequent, thick-walled and branched.
