Abstract

The morphology and taxonomy ofAulacoseira taxa, the dominant group of diatoms in a small glacial lake in the Retezat Mts (TDB-I) were studied in specimens from late glacial and Holocene sediments. Seven species were identified and evaluated by light and scanning electron microscopy. The results of these observations showed some variability of morphological features within the mountain species populations from a poorly investigated part of Europe. Aulacoseira laevissima, A. perglabra and A. pfaffiana are new for the Romanian flora as well as for this region. We confirm the existence of a low-mantle Aulacoseira species, published earlier but not described formally, in the South Carpathian mountain region.
