Colletotrichum siamense causing anthracnose in Bauhinia forficata subsp. pruinosa in Argentina

Bauhinia forficata subsp. pruinosa is a common perennial tree species native to South America that belongs to the Fabaceae. In December 2010 and 2011, plants from a nursery located in the province of Buenos Aires, Argentina presented typical symptoms of anthracnose. We isolated from the lesions of diseased leaves a fungus that based on morpho- logical as well as the ITS (KC132841) and β-tubulin se- quences (KJ829534) was identified as Colletotrichum siamense. After 12 days leaves inoculated with the fungal spore suspension developed lesions similar to those observed innatural infections.Thefunguswasthenre-isolated fulfilling Koch's Postulates. To our knowledge, this is the first report of Colletotrichum siamense causing anthracnose in Bauhinia forficata subsp. pruinosa in Argentina.
