Stemphylium is a well-established genus typified with S. botryosum Wallr. (Woudenberg et al. 2017). It includes dematiaceous hyphomycetes and can be distinguished from other hyphomycetes in Pleosporaceae by having phaeodictyospores produced by the percurrent proliferation in its conidiophores, and apically swollen conidiogenous cells (Köhl et al. 2009). Stemphylium species are mostly pathogens on a wide range of vegetable plants, including tomato, lettuce, beans, pea and fruits (Câmara et al. 2002, Woudenberg et al. 2017, Brahmanage et al. 2018, 2019).

Type species: Stemphylium botryosum Wallr.

Other accepted species: Species Fungorum – search Stemphylium.
