This paper deals with ten species of Phoma, characterized by thick-walled pseudoparenchymatous pycnidia. They superficially resemble the thick-walled pycnidial phenotype in species of Phoma sect. Plenodomus, but scleroplectenchyma is lacking and teleomorphs belong to Didymella, not Leptosphaeria. Keys and indices of host-fungus and fungus-host relations are provided and short comments on the ecology and distribution of the taxa are given.
