N2 - Leaf and stem spots are among the most important diseases compromising ornamental plants worldwide. In this study, Paraphoma garibaldii sp. nov. is described from leaf lesions on Campanula rapunculoides in Piedmont, Northern Italy. The new species was characterised using a polyphasic approach including morphological characterisation and a multilocus molecular phylogenetic analysis based on partial nucleotide sequences of the translation elongation factor 1-α (tef1), the internal transcribed spacers (ITS) region and the β-tubulin (tub2) markers. Pathogenicity tests and the fulfilment of Koch’s postulates confirm P. garibaldii as a novel foliar pathogen of Campanula rapunculoides. Presently, the fungal infection due to Paraphoma garibaldii is known from a single location in Italy, and further surveys are required to determine its distribution and relative importance.
