Chlorophyceae, DesmidialesAbstract
The paper presents the characteristics and description along with the original drawings of two taxa of the order Desmidiales (Chlorophyceae) that have not been recorded in the world so far. They belong to the species Micrasterias crux-melitensis Ehrenberg ex Ralfs and the species Xanthidium fasciculatum Ehrenberg. The found specimens are characterised by different morphological features, which have not been recorded in the descriptions of forms and typical varieties representing these genera in the world flora. Single cells of those varieties were present in the materials collected during fieldwork carried out as part of the reconnaissance and registration of phycoflora habitats of moss bog ecosystems in Western Pomerania.
