Conidial pools of aquatic hyphomycetes were sampled by membrane filtration at four sites along two tributaries of the Morgó stream, Hungary. The streams differed in water chemistry and in composition of riparian vegetation. Somewhat more fungal species were observed in the softwater stream, but the numbers of conidia in the hardwater stream were higher. The composition of the conidial assemblages differed considerably in the two streams. Only two species – Clavariopsis aquatica and Flagellospora curvula ndash; occurred among the top-ranked species at all sites of both streams. Opposite patterns of conidial concentrations in a downstream direction were obtained in the two tributaries. The ratio of scolecoconidia in the conidial pool in one tributary (hardwater) was noticeably high. The suggestion that the abundance of woody substrata in low-order streams may have a structuring effect on aquatic hyphomycete communities is conveyed.
