Savoryellomycetidae, Pleurotheciales, Pleurotheciaceae, Pleurotheciella

Index Fungorum number: IF 564282; 11 species with sequence data.


Saprobic on aquatic plant tissues. Sexual morph: Perithecia nonstromatic, grouped or solitary, venter superficial to semi-immersed, subglobose, dark brown, glabrous, slightly rough surface, ostiolate, papillate. Ostioles periphysate. Peridium leathery to fragile, two-layered, outer layer made up of brown to dark brown cells, inner layer composed of hyaline to pale brown cells. Paraphyses numerous, septate, hyaline, tapering distally, longer than the asci. Asci 8-spored, unitunicate, cylindrical-clavate, short-pedicellate, with J- apical ring.  Ascospores hyaline to subhyaline, ellipsoidal-fusiform, septate, lacking appendages or mucilaginous sheath. Asexual morph: Conidiophores macronematous, mononematous, subhyaline or hyaline, sparingly branched or unbranched, septate, often reduced to conidiogenous cells. Conidiogenous cells subhyaline to hyaline, integrated, terminal or intercalary, usually polyblastic, often extending sympodially, denticulate. Conidia hyaline, ellipsoidal to obovoidal or clavate, subcylindrical to fusiform, aseptate to multi-septate, smooth-walled (adapted from Réblová et al. 2012, Luo et al. 2019).


Type: Pleurotheciella rivularia Réblová, Seifert & J. Fourn., in Réblová, Seifert, Fournier & Štěpánek, Mycologia 104(6): 1304 (2012)



Notes: Pleurotheciella was established by Réblová et al. (2012) with a dactylaria-like asexual morph. The genus is characterised by unbranched to sparingly branched, septate conidiophores, integrated conidiogenous cells with denticles and ellipsoidal to clavate, hyaline, 0–several-septate conidia (Réblová et al. 2012) (notes from Hyde et al. 2020).
