Saprobic in terrestrial habitats. Sexual stateAscomata rarely small, usually medium-sized, immersed usually under a thin clypeus, scattered to gregarious, with flattened top and rounded pore-like ostiole, coriaceous. Peridium 2-layered, outer layer composed of reddish-brown to dark brown small cells, inner layer of pale compressed cells. Hamathecium of dense, cellular pseudoparaphyses. Asci cylindrical to cylindro-clavate with short furcate pedicel. Ascospores one septate, ellipsoid to fusoid, reddish-brown to dark brown. Asexual state: unknown.

Type speciesLetendraea eurotioides Sacc., Michelia 2(no. 6): 73 (1880).

NotesLetendraea was introduced by Saccardo (1880) to accommodate L. eurotioides, which is characterized by superficial, globose to conical ascomata, filiform pseudoparaphyses, obclavate to cylindrical, 8- spored asci, and fusoid to oblong, 1-septate ascospores (Ariyawansa et al. 2014d). Subsequently however taxonomists, placed it in different families when considering the morphological characteristics. For instance, Kodsueb et al. (2006) placed it in Melanommataceae due to similar morphology with Karstenula rhodostoma and Zhang et al. (2012b) referred Letendraea to Montagnulaceae. However, based on multi-gene phylogenies Ariyawansa et al. (2014d) revealed that Letendraea is in Didymosphaeriaceae. 12 Letendraea species are accecpted in Species Fungorum (2020), but sequence data is available for only a few species.
