MATERIAL AND METHODS The area was visited from September 1988 to March 1991 she times. The sampling data are given in Table 1. Table 1.

The measuring methods and instruments were the same as those published earlier (RÉVAY & GÖNCZÖL 1990). The composition of the fungal flora was determined by examining stream foam, submerged leaf and wood samples. Foam samples were fixed with FAA (INGOLD 1975) in the field. Decaying leaf and woody litter were collected in plastic bags and stored in a cool box until transported to the laboratory, then treated in two different ways: a./ dozens of leaves were placed into plastic boxes, filled with distilled water and shaken thoroughly for some minutes to wash off spores from the leaves. After this the water was poured from the leaves into a glass cylinder, the water left to sediment for some time and the sediment was examined by microscope looking for spores, b./an other part of the leaf sample was washed in tap water, then placed in aquarium filled with distilled water and aerated for some days in a refrigerator at 8-10 °C. Decaying twigs and wood pieces also were treated like the leaves. After aeration leaves and woody substrata were examined with a dissecting microscope looking for developing fungi.
