CONTRIBUTIONS TOWARDS A MONOGRAPH OF PHOMA (COELOMYCETES)-III .2. MISAPPLICATIONS OF THE TYPE SPECIES NAME AND THE GENERIC SYNONYMS OF SECTION PLENODOMUS (EXCLUDED SPECIES)

Various old records of Phoma lingam (teleomorph Leptosphaeria maculans ) on non-cruciferous plants proved to be based on misidentifications. In the past the fungus has also often been confused with other fungi o ccurring on crucifers. Forty-five species formerly classified under th e generic synonyms Plenodomus, Diploplenodomus, Leptophoma and Deutero phoma were excluded from Phoma sect. Plenodomus, seventeen of them bei ng non-scleroplecten-chymatous species of Phoma. Asteromella cocogena, Asteromella pomi and Phoma versabilis are described as new species an d twelve new combinations are proposed: Ascochyta aggregata (Hohnel), Cytosporella cenangium (Corda), Fusicoccum hoveniae (Gucevicz), Phacid iella hiemalis (Desm.), Phoma creunta (Sydow), Phoma filarszkyana (Moe sz), Phoma haematites (Petrak), Phoma syriaca (Petrak), Phomopsis alle scheriana (P. Henn.), Phomopsis destruens (Harter), Pleurophoma cava ( Schulzer) and Pyrenochaeta corni (Batista & Vital).
