Endophytic fungi are recognised for producing secondary metabolites that have an effect on the host, such as promoting growth and enhancing plant resilience to biotic and abiotic stress. The objective of this study was to explore endophytic fungi from Citrus reticulata. The endophytic fungi were isolated from both healthy and infected roots, stems, and twigs of C. reticulata. The materials were sterilised and inoculated on potato dextrose agar (PDA) media. The fungi grown were transferred onto fresh PDA plates and identified based on their morphological characteristic, including colonial features, hyphae type, and reproduction structure. Five endophytic fungi were identified as Colletotrichum sp. AJSH2-1, Cylindrocladium sp. BJSH1-2, Rhizopus sp. RJSH1-1, Mucor sp. RJSH1-2, and Aspergillus sp. BJSH1-1. Further study is required to understand the ability of the identified genera in protecting the host from plant disease as well as promoting growth.
