The authors investigated fungal communities associated with eggs of Coregonus lavaretus holsatus species Lake Wdzydze in Kaszuby. A total of 15 fungus species were found to grow on the studied eggs: Achlya americana, A. oblongata, A. treleaseana, Aphanomyces frigidophilus, A. irregularis, A. parasiticus, Aplanes androgynus, Saprolegnia ferax, S. parasitica, S. salmonis, S. shikotsuensis, Pythium aquatile, P. pulchrum, P. thalassium, and P. torulosum. Worth a special note was the finding of Aphanomyces frigidophilus and Saprolegnia salmonis, new to Polish waters. The results obtained may be important to ichthyopathologists, because 8 of the above-mentioned fungi are known as necrotrophs or parasites of fishes.
Zbadano zawartość metali (Cd, Pb, Ag, Cu, Zn, Mn i Fe) w owocnikach 19 gatunków grzybów z rodzaju: Pieprznik (Cantharellus), Maślak (Suillus), Podgrzybek (Xerocomus), Borowik (Boletus), Koźlarz (Leccinum) i Gołąbek (Russula) zebranych na terenie Borów Tucholskich i lasów kaszubskich w 1989 r. Metale oznaczono metodą AAS. Zbadane grzyby cechowała na ogół duża zawartość ołowiu.

The concentrations of Pb, Cd, Ag, Mn, Cu, Zn, and Fe were determined in the fruiting bodies of 19 species of wild growing mushrooms of Cantharellus sp., Suillus sp., Xerocomus sp.. Boletus sp., Leccinum sp., and Russula sp. collected in forest areas of District of Gdańsk in 1989. The method of measurement was flame AAS after dry ashing of the samples. The following concentration ranges for lead, cadmium, silver, manganese, copper, zinc, and iron were found: 2.8 - 47 mg/kg, 0.08 - 12 mg/kg, 0.06 - 3.8 mg/kg, 2.0 - 46 mg/kg, 0.52 - 91 mg/kg, 4.4 - 100 mg/kg, and 8.8 - 390 mg/kg dry weight, respectively.
