Embarria Wanas., Camporesi & K.D. Hyde
Embarria was introduced in Phaeosphaeriaceae (Pleosporales, Dothideomycetes) by Wanasinghe et al. (2018) to accommodate a new combination, E. clematidis (≡ Allophaeosphaeria clematidis) based on multi-gene phylogenetic analyses of a combined LSU, SSU, ITS and tef sequence data. The type species Embarria clematidis, was reported as a saprobe in Italy from dead and hanging branches of Clematis vitalba (Ranunculaceae) (Ariyawansa et al. 2015) and recollected from dead aerial stems of Agrostis stolonifera L. (Poaceae) (Wanasinghe et al. 2018). Embarria is known only from its sexual state and is characterized by coriaceous, ostiolate ascomata, bitunicate, fissitunicate asci with a minute ocular chamber, and ellipsoidal to fusoid, asymmetrical, muriform ascospores with sheaths (Ariyawansa et al. 2015, Wanasinghe et al. 2018). Embarria is morphologically similar to Dematiopleospora in terms of asci and ascospores, however, it differs from the latter by having distinct ascomata. Brown setae are present on the ostioles in Dematiopleospora while the ascomata of Embarria lack seta (Wanasinghe et al. 2018).
