Stomatocyst 29 Caba a is a pollen grain, not a chrysophyte cyst

Stomatocyst 29 Caba a was described from the abie Oko lake in the Tatra Mts, Poland, in 2005 as a chrysophycean stomatocyst new to science. The examination of the recently found specimens in the Dwoisty Staw G sienicowy lake in the Tatra Mts, including their chemical composition, showed that stomatocyst 29 is not a cyst, but a pollen grain.
