ABSTRACTThe phyllosphere mycoflora ofC. incanus L., A. unedoL. andQ. cocciferaL. and its seasonal variation were studied by means of a tape impression culture method.The number of colonies per cm2was highest on leaves ofC. incanusand lower onA. unedoandQ. coccifera.The seasonal fluctuation of 27 fungal forms is illustrated. The dominant fungal species wereAspergillus niger, Cladosporium cladosporioides, Mucor hiemalis, Penicillium frequentans, P. funiculosum, P. verrucosum, Rhizopus stoloniferandTrichoderma pseudokoningii.The abundance of each fungal species was different in the four seasons.There were 6 resident fungal specics:Alternaria alternata, A. flavus, A. versicolor, C. cladosporioides, T. pseudokoningiiand white sterile mycelium.
