Abstract

A new endophytic species of Colletotrichum was isolated from an endangered orchid species, Cattleya jongheana in the Parque Estadual da Serra Negra, from the state of Minas Gerais, Brazil. It is described and illustrated as Colletotrichum serranegrense sp. nov. in this study. Morphology and multi-locus phylogenetic analyses based on combined ITS, ACT, TUB2 and CHS-1 sequence data revealed that these isolates were in the Colletotrichum gigasporum species complex and confirmed differences in this compared to other species in this genus.
