Abstract

Silica-scaled flagellates (synurophyceae) of the „Mestecanisu de la Reci” Covasna County, Transylvania, Romania. The „Mestecanisu de la Reci” („Rétyi Nyír”) is an extended sandy area situated in the Brasov Depression, southeast of Transylvania, between the city of Sf. Gheorghe and Covasna town, near the village of Reci (Réty). The peculiar landscape of the region is due to the eolian sand dunes that had been formed at the beginning of Holocene after the Rau Negru („Feketeügy”) river emptied the ancient Quaternary lake basin. Later, due to the raising of ground water level, small pools and bogs have been formed in the hundreds of small depressions formed among the dunes. The present paper deals with the silica-scaled chyrophytes collected during the spring and autumn of 1996 and 1997, from such small pools and bogs, situated mostly in the protected area (Nature Reserve) of the „Mestecanisu de la Reci”. There have been identified 23 taxa: 17 Mallomonas and 6 Synura species. The following taxa have not yet been recorded in the „Mestecanisu de la Reci” : Mallomonas acaroides, M. annulata, M lelymene and Synura lapponica.
