Chrysophyte stomatocysts from sediments in a manmade water reservoir in central Poland

Twelve chrysophyte stomatocysts are reported from sediments in a man-made water reservoir in the village of Wymysl6w in central Poland. Three morphotypes are described as new to science: stomatocysts #40, #41 and #42. The descriptions of two other stomatocysts, 161 Zeeb & Smot 1993 emend. Piqtek J. and 198 Duff & Smol 1994, forma A Pla 2001 emend. Piqtek J., are emended to include some additional morphological characters, which had not been observed previously. The two morphotypes are also newly reported from Poland. Stomatocyst 171 Zeeb & Smol 1993 is recorded in Poland for the first time from extant material.
