Abstract

In 175 mud samples collected on 25 transversal section of the lake in September, 1968, 108 species of algae have been identified showing the following distribution: Cyanophyta 12; Euglenophyta 4; Pyrrophyta 1; Chrysophyta 68; Chlorophyta 22; Mycophyta 1. Some of the identified species are more frequent in the south-western while others in the north-eastern part of the lake. The highest number of species and individuals of algae was found, apart from some exceptions, in the samples of collecting sites 1, and 2, being near the southern shoreline of Lake Balaton (336.000/dm2, collecting site No. XVII/1). The relation between the living and dead algae was at some places 1 : 1 but as high as 1 : 4 was also recorded.
