Fungal isolates were recovered from symptomatic leaves of naranjilla Solanum quitoense Lam. sampled in Pastaza province, an important production region in eastern Ecuadorian Amazon. Filamentous fungi were identified with molecular methods based on ITS and ribosomal DNA sequencing. Among 68 recorded fungi, the isolation of mycobiota resulted in 14 taxa. Diaporthe citri, D. schini, and Xylaria berteri were the most frequently isolated species. To our knowledge more than 90 % of taxa recovered in this study are reported for the first time in S. quitoense. Diversity indexes suggest that symptomatic tissues represent a moderately diverse reservoir for fungal species. The latter may act as a significant source of novel molecules with agronomic and pharmaceutical properties considering their capacity to survive within unhealthy foliar tissues. We also expect this study to facilitate the enforcement of biological control measures in Neotropical crops of commercial interest.
