Studies of aquatic fungi. XIX. Aquatic fungi of the Rudawka River.

Studies of aquatic fungi were carried out in the annual cycle in the years 1987-1989 against a background of hydrochemical relations in the Rudawka River, a tributary of the Orlanka. 35 species of aquatic fungi were found, of which a prevailing number were reported many times in various water reservoirs. Such species, however, as Olpidium entophytum, Achlyogeton entophytum, Rhizidium verrucosum, Catenaria sphaerocarpa, Leptolegniella keratinophila and Zoophagus tentaclum are new to Polish hydromycoflora. In summer months (July-August) the mycoflora of this river was poor, the occurrence of various species of aquatic fungi increased in autumn and spring, and less so in winter.
