N2 - The genus Micropsalliota is a group of saprotrophic mushrooms, characterized by small to medium-sized basidiomata with fibrillose-squamulose or glabrous pilei, ellipsoid to amygdaliform or cymbiform basidiospores and cheilocystidia that vary in shape from clavate to ventricose or lageniform with more or less a capitate apex. In this study, we described a new species of Micropsalliota from southern Oman. Species description is based on morphological features of basidiomata and phylogenetic analyses of nuc ribosomal DNA internal transcribed spacer (ITS) and D1–D2 domains of the 28S region. The new species Micropsalliota ventricocystidiata is characterized by a medium-sized basidiomata, with plano-convex pileus, covered with reddish-brown squamules and basidiospores are ellipsoid to amygdaliform with acute apex in side view and oblong in face view, measuring 7.5–8.5 × 4.5–5 µm. Morphological comparison of M. ventricocystidiata with respect to other species of the genus is provided. We discussed that species of the genus can be divided into two groups based on their pileus morphology and basidiospores size.
