Classification: Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic, parasitic on twigs and isolated from soil. Colonies discrete, effuse dark brown to black. Mycelium immersed to superficial, branched, septate, hyaline to brown. Sexual morph: Ascomata mostly scattered, immersed, compressed globose, with central, papillate ostiole. Peridium composed of two layers. Hamathecium comprising numerous, hyaline, septate, branched, cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindric to clavate, pedicellate, apically rounded with an ocular chamber. Ascospores overlapping 2–3-seriate, fusiform, brown, 1– 3-septate. Asexual morph: Conidiophores reduced to conidiogenous cells, or erect moniliform, brown. Conidiogenous cells solitary on mycelium, or terminal on conidiophores erect, smooth to verruculose, brown, polyblastic, or reduced to inconspicuous loci on hyphae. Conidia solitary origin acrogenously branched chains, smooth or with warts, septate, fusoid-ellipsoidal, clavate or ovoid, brown, frequently constricted at septa, with cells or septa darker pigmented that the rest of conidium; conidia in chains or not, at times becoming cupulate, with secondary conidia.

Notes: Crous et al. (2015a) introduced Latoruaceae to accommodate Latorua and Polyschema in order Pleosporales. These taxa were isolated mainly from soil (Crous et al. 2015a). Matsushimamyces and Pseudoasteromassaria are other accepted genera in the family (Ariyawansa et al. 2015a, Sharma et al. 2015).

Type genus: Latorua Crous.
