Sarimanas

Sarimanas M. Matsum., K. Hiray. & Kaz. Tanaka, in Liu et al., Fungal Diversity: 10.1007/s13225-015-0324-y, [126] (2015).

 Index Fungorum number: IF 551052; Facesoffungi number: FoF 00497, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.

Saprobic on host. Sexual morph: Ascomata immersed, scattered or 2–3 gregarious, globose to subglobose, ostiolate. Neck short papillate, without clypeus. Ascomatal wall composed of polygonal thin-walled cells. Hamathecium cellular, numerous, septate. Asci fissitunicate, cylindrical to ovoid, with a short stipe. Ascospores broadly fusiform with rounded ends, uniseptate, hyaline, smooth-walled, with an entire gelatinous sheath. Asexual morph: Unknown (adapted from Liu et al. 2015).

 Type species: Sarimanas shirakamiense M. Matsum., K. Hiray. & Kaz. Tanaka

Notes: Sarimanas is characterised by immersed, scattered or 2–3 gregarious ascomata, short papillate ostiolate neck, cylindrical to ovoid asci and broadly fusiformuniseptate, hyaline ascospores with rounded ends and an entire sheath. Sarimanas resembles Massarina but differs in that the latter has clypeate ascomata and belongs to Massarinaceae (Zhang et al. 2012a, Liu et al. 2015). Sarimanas also resembles Wettsteinina in ascospore morphology but differs in that the latter has ascomata deficient in a hamathecium when mature (Zhang et al. 2012a, b). Sarimanas is closely related to genera in Melanommataceae, such as Aposphaeria and Herpotrichia based on phylogenetic analyses of LSU and SSU sequence data but is morphologically distinct (Liu et al. 2015). Sarimanas is a well-defined and clearly distinct genus in Melanommataceae. Molecular markers available for Sarimanas are ITS, SSU and LSU.
