Aplosporellaceae Slippers, Boissin & Crous, Stud. Mycol. 76(1): 41 (2013)                  

Index Fungorum: IF 805795; Facesoffungi number: FoF 00113, 13 species.

Sexual morph: Stromata pseudothecial, multiloculate ascomata with multi-layered, dark brown walls, embedded in stromatic tissue. Hamathecium comprising hyphoid, hyaline pseudoparaphyses. Asci bitunicate, mostly with a thick endotunica, clavate, with a well-developed ocular chamber and intermixed with pseudoparaphyses. Ascospores 1–2-seriate, ellipsoid to ovoid, mostly aseptate, or septate, hyaline to pigmented, lacking mucoid appendages or sheaths (Slippers et al. 2013; Liu et al. 2012; Thambugala et al. 2014a; photoplates of sexual characters can be seen in Ekanayaka et al. 2016). Asexual morph: Coelomycetous. Conidiomata pycnidial, multilocular, embedded in stromatic tissues. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, phialidic. Conidia ellipsoid to subcylindrical, initially hyaline, thin-walled and smooth, becoming pigmented, thick-walled and spinulose, aseptate (Sutton 1980).

Type: Aplosporella Speg.

Notes: Aplosporellaceae was introduced by Slippers et al. (2013) to accommodate Aplosporella and Bagnisiella. Currently two genera (Aplosporella and Alanomyces) are accepted in this family. This family is phylogenetically close to Botryosphaeriaceae. Liu et al. (2017a), using evolutionary evidence, questioned whether this family was introduced unnecessarily and should be regarded as a genus. However, based on morphology, phylogeny and evolutionary divergence times, Phillips et al. (2019) regarded Aplosporellaceae as a distinct family.
