Study in vivo and in vitro of the ‘Ascochyta’ -pathogen of lupin, indigenous to America, showed its conidial dimorphism. The phomoid phenotype developing in vitro and sometimes also in vivo is described as a new species of Phoma sect. Heterospora. The ascochytoid-stagonosporoid phenotype commonly occurring in association with disease symptoms is transferred to Stagonosporopsis.
