Chrysophycean stomatocysts from the Staw Toporowy Nizni lake (Tatra National Park, Poland)

摘要

Thirty-six chrysophycean stomatocysts are reported from the dystrophic Staw Toporowy Nizni lake in the Tatra National Park, Poland. Of these, 7 morphotypes are new to science, 10 are new to Europe, and 13 are new to Poland. SEM micrographs and data on distribution are provided for each stomatocyst. Synonimizations of two stomatocysts are proposed: stomatocyst 58 Hansen 2001 with stomatocyst 117 Zeeb et al. 1990, and stomatocyst 91 Hansen 2001 with stomatocyst 239 Duff et al. 1995. The number of chrysophycean stomatocysts recorded from Poland is currently estimated to comprise 65 extant morphotypes.
