Studies on the vertical distribution of marine fungi in a Rhizophora apiculata mangrove stand in Morib, Selangor were carried out in June 1993 and June to November 1997. Prop roots, subterranean roots and overhanging branches of R. apiculata were collected from three intertidal levels namely upper (high water mark), middle and lower. Fifty-three species were recorded including 39 ascomycetes, 13 deuteromycetes and one basidiomycete. The most common fungi were Halocyphina villosa (frequency occurrence 21%), Kallichroma tethys (20%), Lulworthia grandispora (18%), Leptosphaeria australiensis (16%), Julella avicenniae (15%) and Massarina ramunculicola (13%). The fungi were found to be vertically zoned, some were limited to the upper level such as Pyrenographa xylographoides, Julella avicenniae and Aigialus grandis or lower level such as Trichocladium achrasporum and T. alopallonellum, while only five species showed a broader distribution, being present at all levels: Leptosphaeria australiensis, Halocyphina villosa, Cryptovalsa sp., Lulworthia grandispora and Lulworthia sp. The greatest diversity of marine fungi were collected from the middle level with a Shannon Diversity Index of 5.9 while the Jaccard Similarity Index of 2.25 indicated that the upper and middle levels were the most similar in terms of species composition. Fungi with certain characteristics were also limited to particular levels, for example, carbonaceous and superficial ascomata were confined above mean tide while membranous walls and immersed ascomata were common below mean tide level.
