Notes – Allophaeosphaeria was introduced by Liu et al. (2015) to accommodate pleospora-like taxa having globose to subglobose ascomata, raised immersed to erumpent through host tissue, with protruding papilla. The peridium composed of two type layers of dark pigmented, carbonaceous cell of the outer layers, with hyaline, thick-walled, pseudoparenchymatous cells of the inner layers. Asci are 8-spored, fissitunicate, cylindrical to cylindric-clavate, with short, narrow to knob-like pedicel, with lacking pseudoparaphyses. Ascospores are muriform, ellipsoidal to broad fusiform, light brown to brown, smooth-walled, with indistinct mucilagenous sheath (Ariyawansa et al. 2015a, Liu et al. 2015). Two species were initially accommodated in this genus viz. A. dactylidis Wanas. et al. and the generic type,
A. muriformis (Liu et al. 2015). Ariyawansa et al. (2015a) introduced other three species in this genus based on molecular phylogeny and also reported the asexual morph as coelomycetous, septoriella-like (A. subcylindrospora). Wanasinghe et al. (2018c) introduced a new genus Dactylidina and transferred A. dactylidis to Dactylidina as D. dactylidis. Marin-Felix et al. (2019) attempted to resolve the phylogenetic problem among the genera claded with Septoriella. Based on phylogenetic analysis of ITS, LSU and rpb-2 sequence matrix, Marin-Felix et al. (2019) synonymized Allosphaeosphaeria under Septoriella. Whereas, A. dactylidis was designated as the generic type of the new genus Dactylidina by Wanasinghe et al. (2018c) but the species was currently transferred to Septoriella as S. neodactylidis by Marin-Felix et al. (2019). However, the morphological features of these genera are different in their sexual morphs but overlap in some characters of their asexual morph. The congeneric status of these genera is still questionable. According to the treatment in Hyde et al. (2020b), we tentative reinstate the Allosphaeosphaeria pending further studies.
