The diversity of cercosporoid hyphomycetes - new species, combinations, names and morphological clarifications

The new species Stenella leucothoes and S. pittospori are described, and the new combinations and new names Asperisporium rafinesquiae, Passolora euphorbiicola, P. sterculiacearum, Pseudocercospora campanulae, P. lonicerigena, P. photiniae-serrulatae, P. physostegiae and Stenella prosopidis are introduced. Based on re-examinations of type collections, the taxonomic status of Cercospora saccharini and C. rhagadioli as genuine species of Cercospora, morphologically distinct from C. apii s. l., could be confirmed, and it could be demonstrated that Cercospora pittospori had been correctly reallocated to Pseudocereospora. Furthermore, the nomenclature of Passalora polygonati-maximoviczii, Pseudocercospora dendrobii and P. sacchari is discussed, the status of Cercospora solani-nigri as a synonym of Pseudocercospora atromarginalis is verified, and new records of Passalora bocconiae and Pseudocercospora thouiniae are added
