Resumen:
Urban forests, which are highly valuable for the urban environment, include trees from city streets that might be susceptible to wood-decay fungi. Fungal endophytes can colonize healthy plant tissues without causing external disease symptoms in standing trees. In this work, the diversity of endophytes isolated from wood of Platanus acerifolia from Buenos Aires City (Argentina) is described and related to different levels of urban disturbance, tree age and presence of wood-decay basidiomycetes. Samples were obtained from twenty-eight asymptomatic trees (1643 wood core fragments) and seventy-five symptomatic trees (1516 wood sample fragments) from four sites with different levels of human disturbance. Fungal isolates were morphologically identified and potential wood-decay isolates were phylogenetically analyzed. Twenty-seven endophytic taxa, including five basidiomycetes were identified. The multivariate analysis suggested that the endophyte community of wood is highly influenced by the level of urban disturbance, followed by tree age and presence of potential pathogenic basidiomycetes
