The phylogenetic relationship of Jattaea and Wegelina, two morphologically related genera of the Calosphaeriales, is analyzed in two molecular analyses using the Internal transcribed spacer region of the DNA operon, and the nuclear large and small subunits of ribosomal DNA combined with the second largest subunit of RNA polymerase for a multigene analysis. Morphological and molecular data show that two lectotype species Jattaea algeriensis and Wegelina discreta are congeneric. The name Jattaea is accepted to include species with hyaline, allantoid to suballantoid ascospores in clavate, stipitate asci without apical annulus borne on individual cells on ascogenous hyphae and with phialophora-like anamorphs produced in axenic culture. Twelve species are accepted in Jattaea, the concept of the genus is outlined and a key to its species is provided. The genera Phragmocalosphaeria and Wegelina are reduced to the synonymy of Jattaea.
