Saprobic on submerged decayed stem. Sexual morph: Ascomata solitary or aggregated in stroma, immersed to erumpent, uniloculate, globose to subglobose, sometimes with flattened base, glabrous, dark brown to black, coriaceous to sub-carbonaceous, with cylindrical ostiolar canals, with ostiolate papilla, usually stain the substrate purple. Peridium two-layered, comprising hyaline to yellow-brown, to dark brown, thin-walled cells of textura angularis. Pseudoparaphyses numerous, cellular, thin, hypha-like, septate, branched, persistent, emerged into the ostiolar canal. Asci 4- to 8-spored, bitunicate, fissitunicate, cylindric-clavate, pedicellate, with ocular chamber. Ascospores uni- to bi-seriate, fusiform to clavate, with rounded ends, straight or slightly curved, yellow- to reddish- to dark-brown, transversely septate, occasionally with one longitudinal or oblique septum, smooth- or rough-walled, surrounded by prominent gelatinous sheath (Abdel-Aziz 2016a). Asexual morph: Coelomycetous. Conidiomata solitary or aggregated, superficial, acervular, pearl white to dull yellow. Peridium composed of hyaline cells of textura intricata, embedded in gel. Conidiophores lining the acervuli wall, branched and septate, hyaline, smooth, embedded in gel. Conidiogenous cells holoblastic, terminal, cylindrical to sub-cylindrical, hyaline, smooth, bearing a single conidium. Conidia solitary, ellipsoidal, straight, hyaline, aseptate, smooth, thin-walled, with apical, sub-apical and basal appendages (Abdel-Aziz and Abdel-Wahab 2010).
Notes: Lolia was introduced by Abdel-Aziz and Abdel-Wahab (2010) to accommodate the asexual species L. aquatica collected on decayed stem of Phragmites australis from Egypt. Lolia is characterized by acervular conidiomata, clavate, ellipsoidal, cylindrical conidia with apical, sub-apical and basal appendages (Abdel-Aziz and Abdel-Wahab 2010). Its sexual morph was later collected on submerged decayed stem of Phragmites australis from River Nile (Abdel-Aziz 2016a). The authors assigned two holotypes, IMI 398675 and CBS H-22130, based on both asexual and sexual morphs, respectively, which does not conform to “One fungus, one name” (Abdel-Aziz and Abdel-Wahab 2010; Abdel-Aziz 2016a). We select the first holotype (IMI 398675, ex-type living culture MF644) as the exclusive holotype.
The second species L. dictyospora Abdel-Aziz was also collected from River Nile, but on submerged decayed rachis of Phoenix dactylifera (Abdel-Aziz 2016a). The special characters of L. dictyospora, such as 4- to 8-spored asci and clavate ascospores occasionally with one longitudinal or oblique septa, distinguish it from L. aquatica (Abdel-Aziz 2016a). Lolia aquatica has cellular, hypha-like pseudoparaphyses, while L. dictyospora has trabeculate, filiform pseudoparaphyses. Two species cluster together, but without bootstrap support (Abdel-Aziz 2016a).
