A23D87F26F68FFE5FF7C70433B06FCEF.taxon	discussion	Notes: — The phylogenetic analysis showed that two isolates of Pseudokeissleriella formed a monophyletic clade in Lentitheciaceae and is closely related to the monotypic genera Katumotoa (type: Ka. bambusicola) and Neoophiosphaerella (type: N. sasicola) (FIGURE 1). Pseudokeissleriella resembles Katumotoa in having immersed, subglobose ascomata, but they can be distinguished by the ascospores. Pseudokeissleriella has fusiform ascospores tapering to subobtuse ends, with a swollen upper cell near the median septum and mucilaginous sheath, while Katumotoa has apiosporous ascospores with distinctive elongated bipolar mucilaginous sheath (Tanaka & Harada 2005). Pseudokeissleriella differs from Neoophiosphaerella in having immersed, globose ascomata and fusiform, 1 - septate ascospores, while the latter has superficial, hemispherical, with clypei ascomata and filiform, multi-septate ascospores (Tanaka et al. 2015). In addition, referring to the recommendations of Jeewon & Hyde (2016) for the establishment of species boundaries among fungi, Pseudokeissleriella can be distinguished from Ka. bambusicola and N. sasicola based on sequences data comparison from LSU (14 / 831; 11 / 831) and ITS (25 / 548; 36 / 548). The ascospores of Pseudokeissleriella are somewhat similar to Keissleriella. However, Keissleriella is thought to have a striking feature that most of their species have brown or black setae inside or around the ostiole. Pseudokeissleriella can be easily distinguished from the latter by the absence of setae around the ostiole, as well as the distance in molecular phylogeny.	en	Yang, Yi, Zhang, Sheng-Nan, Yu, Xian-Dong, Liu, Jian-Kui (2022): Pseudokeissleriella bambusicola gen. et sp. nov.
