Phylogeny of the genus <i>Volvariella</i> with the description of one new species and two new records from Oman

In the present study, a newly found species of <i>Volvariella</i> from Oman is described and named <i>V. darbatica</i>. Evidence for this decision is based on morphology and multigene phylogeny. <i>Volvariella darbatica</i> is characterized by small-sized basidiomata, pale pinkish to pale brownish pileus, and ellipsoid to ovoid basidiospores measuring 5.0-6.0 × 4.0-4.5 µm. Colour photographs of basidiomata and illustrations of anatomical characters are provided, along with the phylogenetic trees of the genus <i>Volvariella</i> and the suborder <i>Pluteineae</i> (where family <i>Volvariellaceae</i> is nested). Morphological similarities with closely related species are discussed. Furthermore, we also report the presence of <i>Volvariella cubensis</i> and <i>V. sathei</i> in Oman, extending the distribution of these species. <i>Volvariella sathei</i> was previously known only from its type locality in India. <b>Citation:</b> Hussain S, Al-Kharousi M, Al-Maqbali D, Al-Owaisi AA, Velazhahan R, Al-Sadi AM, Al-Yahya'ei MN (2025).
