  "abstract": "A leaf disease causing leaf fall in Hevea brasiliensis recently appeared in Southeast Asia and threatens rubber production. While tentatively associated with the Pestalotiopsis, Colletotrichum, and Neopestalotiopsis species, its etiology remains poorly characterized. This study aims to identify the fungal community associated with symptomatic rubber leaves using culture-independent ITS amplicon sequencing. Leaf samples representing three levels of symptom severity were collected from Central Java and South Sumatra. Fungal community analysis revealed that geographic origin, rather than symptom severity, was the driver of community clustering. Phyllosticta and Colletotrichum were consistently dominant across all samples, with Phyllosticta displaying higher abundance. Minor proportions of Pestalotiopsis, Neopestalotiopsis, Corynespora, and Pestalotia were also detected. Fungal isolates collected from diseased leaves in the same regions were identified as Neopestalotiopsis, Pestalotiopsis, and Colletotrichum and placed in a two-loci (ITS and β-tubulin) phylogenetic tree to clarify their identity at species level. Pathogenicity assays confirmed that representative isolates reproduced field symptoms. However, no Phyllosticta isolate was obtained, probably due to slow growth. This metabarcoding assessment of the phyllosphere mycobiota in diseased rubber leaves identified Phyllosticta as a critical yet overlooked component of the leaf fall disease complex, providing insights into fungal ecology and pathogenic interactions underlying this emerging production threat.",
