Discosia

Discosia is a genus of plant pathogens in the family Sporocadaceae. It was published by Marie-Anne Libert in 1837. The genus was re-studied by Subramanian and Reddy (1974), who designated Discosia strobilina Lib. ex Sacc. as lectotype for the genus (Nag Raj 1993; Tanaka et al. 2011). Later, when Sphaeria artocreas Tode was transferred to the genus and combined under Discosia artocreas (Tode) Fr., the latter was chosen as lectotype of the genus (Fries 1849; Vanev 1991). Vanev (1991, 1992a, b, c, d) made a detailed taxonomic revision of the genus. On the basis of the location of the conidial septa and appendages, he delimited six sections (Vanev 1991), and to clarify the status of the genus he designated its lectotype as Discosia artocreas (Tode: Fr.) Fr. (Vanev 1992a). In 2015, Senanayake, Indunil C.; Maharachchikumbura, Sajeewa S. N. et al. (2015) moved the genus to its own family Discosiaceae Maharachch. & K.D. Hyde 2015. But in 2016, it was moved back into the family Sporocadaceae.
