Notes: Leptodiscella was introduced by Papendorf (1969) and typified by L. africana which was previously known as Leptodiscus africanus. This genus has hyphomycetous characters, producing conidia, long appendages, chlamydospores present or absent; when present, forming long or short chains, appressoria present or absent; when present ellipsoid to oblong-oval or obovoid. Conidiogenous cells are solitary or aggregated, mono- or polyblastic, sympodial (Papendorf 1969; Matsushima 1975; Udagawa and Toyazaki 1985; Madrid et al. 2012). However, the connectively of sexual and as asexual morphs has not been proven yet, as sexual morphs for any Leptodiscella species have yet to be obtained. Currently, five Leptodiscella species are accepted, namely L. africana, L. brevicatenata, L. chlamydospora,
L. japonica and L. rintelii (Species Fungorum 2021). In this study, we introduce a sexual morph of Leptodiscella species, which was collected from decaying leaves of Ficus septica (Moraceae). We follow Hernandez-Restrepo et al. (2019) and their recent treatment for Leptodiscella species.
