MycoBank:—MB 830134

Diagnosis:—Light orange yellow, slightly umbonate pileus with uplifted margins and whitish to yellowish crowded lamellae, light brown stipe, 6.6–8.3 × 3.9–5.1 µm basidiospores, small urticoid cheilocystidia (16.1–19.6 × 5.1–6.3 µm) and fusoid-ventricose pleurocystidia which are bicellular at the base.

Etymology:—The specific epithet “ kashmirensis ” refers to the locality of the type.
