| fungal pathogen (mis-) identifications: a case study with dna barcodes on melampsora rusts of aspen and white poplar. | wide variation and overlap in morphological characters have led to confusion in species identification within the fungal rust genus melampsora. the melampsora species with uredinial-telial stages on white poplar and aspens are especially prone to misidentification. this group includes the melampsora populnea species complex and the highly destructive pine twisting rust, melampsora pinitorqua, which alternates between hosts in populus section populus and pinus. our objective was to compare morpho ... | 2009 | 19249365 |
