Abstract
A new species of Colletotrichum was described, based on morphology and phylogeny. The fungus was isolated in Madagascar from healthy leaves of Centella asiatica, in Mexico from wild native of Stylosanthes guianensis and in Colombia from Coffea arabica. The fungus differed from the currently related species in the genus by its longer and wider size of conidia. In potato dextrose agar medium supplemented with sterilized leaf powder of Ce. asiatica, the fungus produced fertile perithecia containing asci and unusual long ascospores measuring up to 90 μm. In addition to these morphological characteristics, the maximum parsimony analysis of the ITS region and β-tubulin gene placed the fungus in a distinct clade far from the currently valid Colletotrichum species. Based on the morphological andmolecular characterization, Colletotrichum gigasporum sp. nov. was proposed as a new species in the genus Colletotrichum Corda.
