Allophaeosphaeria

Allophaeosphaeria Ariyaw., Camporesi & K.D. Hyde, in Liu et al., Fungal Diversity 72: 137 (2015)

Index Fungorum number: IF 550997; Facesofungi number: FoF 00494

Etymology: Named after its morphological resemblance to Phaeosphaeria in contrast to the phylogenetic distance between both genera.

Saprobic on dead wood. Sexual morph: Ascomata superficial, globose to subglobose, ostiolate. Ostiole papillate, without periphyses. Peridium comprising 2-layers, outer layer composed of heavily pigmented thick-walled, innermost layer of broad, hyaline compressed rows of cells of textura angularis. Hamathecium lacking pseudoparaphyses. Asci bitunicate, fissitunicate, elongate cylindrical to slightly clavate with an ocular chamber. Ascospores oblong to narrowly oblong, multi-septate, muriform, constricted at each septa, hyaline, pale brown when mature, smooth-walled. Asexual morph: Undetermined.

Type species: Septoriella muriformis (Ariyaw., Camporesi & K.D. Hyde) Y. Marín & Crous 2019

Note: Allophaeosphaeria was introduced by Liu et al. (2015) to accommodate A. muriformia Ariyawansa et al. and A. dactylidis Wanasinghe et al. Allophaeosphaeria also resembles many species of Phaeosphaeria in having a peridium comprising 2–3 layers of brown to dark brown cells of textura angularis and multi-septate ascospores with a gelatinous sheath, but differs in having muriform ascospores (Liu et al. 2015). Ariyawansa et al. (2015) typified Allophaeosphaeria in Allophaeosphaeria muriformis currently synonymized to Septoriella muriformis by Marin-Felix et al. (2019).
