Type species – Ascostratum insigne Syd. & P. Syd., Annls mycol. 10(1): 41 (1912).
Notes – Ascostratum was introduced by Sydow & Sydow (1912a) and was typified by Ascostratum insigne. The genus was placed in Dothideomycetes, genera incertae sedis by Lumbsch & Huhndorf (2010). This genus can be differentiated from other genera of the family by a prominent stalk in ascostromata connecting to the host (Dissanayake et al. 2014). Based on morphology Dissanayake et al. (2014) placed this genus in Myriangiaceae. Fresh collections and sequence data are needed for this genus to establish its familial position in Dothideomycetes.
