Re-interpretation of Cocconia palmae, with description of the genus Dianesea (Ascomycota: Dothideomycetidae)

The original circumscription of Cocconia palmae F. Stevens was found to consist of elements of two unrelated species, belonging to Hysterostomella Speg. (Parmulariaceae) and an undescribed genus of Dothideomycetidae probably referable to the Coccoideaceae respectively. The name Cocconia palmae is typified to represent the latter fungus, for which the new genus Dianesea is introduced.
