Is Phoma rumicicola a synonym of Phoma acetosellae?
Both P. rumicicola and P. acetosellae were described from Rumex. The two species were distinguished by Boerema et al. (1980) on the basis of different growth rates in culture and on the size of the conidiogenous cells. All of the putative P. rumicicola isolates from New Zealand sequenced, including the ex-type isolate (ICMP 10965, CBS 683.79), match genetically cultures acces- sioned into CBS as P. acetosellae (e.g. CBS 179.97, ex Aveskamp et al., 2010). If the P. acetosellae identifications are correct, then the two species are synonyms with P. acetosellae the oldest name. Clarification of this requires an epitype to be selected for P. acetosellae.
