Acremonium camtosporum isolated as an endophyte of Bursera simaruba from Yucatan Peninsula, Mexico. Bursera simaruba (Burseraceae) is a frequent and co-dominant tree of tropical sub-caducifolious forest in the Yucatan Peninsula. This species is important ecologically because it can grow in poor, clay or sandy, saline soils. The Mayan communities use this plant medicinally for its analgesic, antimycotic and anti-inflammatory properties. Bursera simaruba exhibits a notable phenotypic variation associated with an ecotypic differentiation for some ecophysiological characters. Therefore, a diverse endophyte Ascomycota with possible unique genetic diversity inhabit the Yucatan subtropical forest. A preliminary bioprospecting project to search for novel allelochemical compounds from endophytic fungi associated with plant communities at El Eden Ecological Reserve, revealed a distinctive endophytic Ascomycota diversity that produces new bioactive chemical compounds. In the present study, we isolated from the leaves of B. simaruba a rarely isolated fungus, Acremonium camptosporum previously recorded from air and leaf litter of Acacia karroo in South Africa. The Yucatan isolate of A. camptosporum as an endophyte of B. simaruba is characterized by a slow-growing powdery cream culture, verticillately branched conidiophores and plano-convex conidiospores. The morphological and molecular data from sequences of ITS rDNA/28S rDNA agree with the species description.
