|a Black swallow-wort (Vincetoxicum nigrum) is an aggressive invasive vine infesting pastures and fields in the northeastern United States. An unknown fungal pathogen was recovered from foliar lesions occurring on black swallow-wort at two locations in Rhode Island in 2022 and was identified as Boeremia exigua based on morphological and molecular descriptions of eight isolates. The potential weed biological control value of a single isolate, FDWSRU 22-216, was evaluated through colonized agar block and conidial spray inoculations of black swallow-wort. Minor leaf-spotting and tip die-back symptoms were reproduced under controlled conditions but did not appear to substantially reduce the health of infected plants. Since broad host range pathogen species found on weeds may pose a disease threat to crops, cultivated plants including tomato, barley, sunflower, and flax were evaluated for susceptibility to the pathogen. None of these crops developed disease symptoms following inoculation with B. exigua, suggesting that the pathogen population associated with black swallow-wort poses little direct risk to crop production. However, using taxon-specific markers, two B. exigua genotypes, including one that does not correspond to existing reference material, were described. While both genotypes grew most rapidly at 25°C in vitro, the dominant genotype was capable of higher growth rates at 30°C, suggesting potential phenotypic differentiation. This study reports the first instance of B. exigua on a swallow-wort species and highlights the potential for widespread invasive plants to harbor previously undescribed pathogen genotypic diversity. Although B. exigua has limited potential as a living biological control agent for black swallow-wort, the isolates from this study could be screened for production of phytotoxic secondary metabolites with weed suppressive activity
