Euglenophytes reported from karst sink-holes in the Malopolska Upland (Poland, Central Europe)

Abstract

In karst sink-holes within the environs of Czajków, and in an old fishpond within the Skorocice gypsum valley, 24 taxa of euglenophytes, comprising Euglena (10), Phacus (9), Lepocinclis (2), and Trachelomonas (3) were found. Four of them, Phacus elegans Pochmann, Ph. arnoldii Swirenko var. ovatus Popova, Ph. plicatus Conrad, and Ph. curvicauda Swir. var. robusta Allorge & Lefèvre, are new for the Polish flora, and rarely reported worldwide.
