Abstract: | The coelomycete Dwiroopa was determined to be the correct genus for Harknessia lythri, and a new combination is made for this species. The type species of Dwiroopa, D. ramya, is redescribed and illustrated based on the type specimen for which a lectotype is designated. A key to the two species of Dwiroopa is presented along with a discussion of their similarities and differences. The genus Dwiroopa is distinguished from Harknessia by conidial characteristics. In Dwiroopa the macroconidia have widely spaced, longitudinal slits around the conidia and lack a basal appendage, whereas in Harknessia the macroconidia are smooth or have closely spaced, longitudinal slits on only one side of the conidia and often have a true basal appendage. Both Dwiroopa and Harknessia are included in the Diaporthales. |
