| Abstract: | The filamentous fungus flora on standing leaves of Typha latifolia in a bog was followed from late spring to early winter. A seasonal successional change of fungal colonizers was observed. Certain groups of species tended to be specific to a particular physiological condition of leaves. Leaf parasites and common primary saprophytes were major colonizers on the developing leaves. After the flowering time of host plant, facultative parasites invaded the aged leaves and finally became dominant on the dead leaves in early winter. A species of Fusarium, F. chlamydosporum was recognized as a main decomposer of the dead leaves near the water line in 1992. It may largely contribute to a smooth supply of dead aerial leaves for the heterotrophic community in the water. |
