Asexual morph: Stromata superficial, scattered, broad, flattened turbinate, multiloculate, often supported by a stalk at the central point, collapsing when dry, with folded margin, black, coriaceous. Conidiomata pycnidial, multiloculate, immersed in stroma, brown to black, coriaceous. Peridium 1-layered, composed of black to brown cells of textura angularis.

Type species – Botryochora nigra (Torrend) Torrend
Notes – The monotypic genus Botryochora was introduced by Torrend (1914) based on type species Botryochora nigra Torrend (≡ Megalonectria nigra Torrend) which was previously classified in Nectriaceae, Sordariomycetes. Botryochora nigra was found on unidentified bark of trees in Kisanty Congo, Mozambique. This genus was later placed in Dothioraceae by Hawksworth et al. (1995) and Lumbsch and Huhndorf (2010). The genus is characterized by superficial stromata with locules, 8-spored asci and smoky brown ascospores. The asexual morph as observed by Thambugala et al. (2014) is coelomycetous, who transferred the genus to Dothideales, genera incertae sedis based on morphology. We examined another specimen from S, but did not observe any sexual morph of Botryochora nigra. Presently, we follow Thambugala et al. (2014) and place Botryochora in Dothideales genera incertae sedis.
