The rubber tree(Hevea brasiliensis Muell.Arg.) at a certain age can be attacked by diseases caused by fungi. The symptoms of the disease may be form blackish brown spots on the stems, blackish white patches on the petiole, the tip of the leaf wrinkled, etc. This research aimed to find out the types of fungi isolated from the leaves and stems with symptoms of disease on the rubber tree at different age levels. The samples were taken using a cruise method based on the age level i.e. 0-9 months old, 2-5 years old, and > 5 years old. The research findings indicated that there were seven types of fungi found i.e. Fusarium V₁, Colletotrichum V₂, Phytophthora V₃, Aspergillus V₄, Penicillium V₅, Mucor V₆ and Chrysonilia V₇. The leaves aged 0-9 months old the fungi found were Colletotrichum V₂, Phytophthora V₃, and Penicillium V₅; on the leaves aged 2-5 years old i.e. Phytophthora V₃ and Aspergillus V_4; and at age > 5 years old, Fusarium V₁, Phytophthora V₃, Mucor V₆ and Chrysonilia V₇ were found on the stem organ.
