ABSTRACT
The seasonal pattern and mechanism of the distribution of microfungi on dead leaves in a woodland stream were studied. Three different leaf litter types were sampled monthly in three manipulated sectors of the stream. The leaf litters have leaves of European turkey oak (sector O), leaves of alder + willow (sector A-W) and leaves of oak + alder + willow (sector O-A-W). Thirty-nine species of fungi were isolated; fourteen species were common to all three sectors: 3 were restricted to sectors O and O-A-W, 7 to sectors A-W and O-A-W, 3 to sectors O and A-W. and 9 to sector O-A-W. Sectors A-W and O-A-W were most similar in fungal populations, sectors O and A-W most different. Eleven isolates were propagated on turkey oak and alder leaves. Significant weight loss and protein enrichment were noted for some species.
