From the dominant species Flagellospora leucorhynchos were found exclusively in the Deszkametsző. Anguillospora mediocris occurred in both streams, but it accounted for high proportions of the total spores found only in the Deszkametsző. Although in the November samples the conidial numbers of Clavatospora longibrachiata were actually higher in the Deszkametsző, its relative importance was higher in the Bagolybükk. The conidia of Margaritispora aquatica and Tumularia tuberculata were detected in both streams, they were relatively more important in the Bagolybükk. The majority of frequent species varied in the timing of their maximum conidial production. DISCUSSION In the present and two earlier studies (GÖNCZÖL and RÉVAY 1999, 2003) the species richness and the conidial numbers of the aquatic hyphomycetes have been
