Contamination in 24 algal cultures from the collection of the Department of Botany, Charles University of Prague, was determined. All cultures were contaminated. They contained fungi, bacteria, actinomycetes, in some cases fungi along with bacteria. There were isolated 10 species of fungi: Verticillium lecanii (Zimm.) Viégas, Acremonium kiliense Grütz, Penicillium notatum Westl., Penicillium sp., Aspergillus nidulans (Eidam) Wint., Aspergillus versicolor (Vuill.) Tiraboschi, Tritirachium album Limber, Cladosporium sp., Paecilomyces sp., Acremonium sp. Contaminants were able to grow even in algal cultures cultivated on mineral media. Analysis of contamination indicated that some contaminants were brought into cultures from the original environment of algae, some of them by following manipulation with cultures.
