Abstract
Three new morphotypes of chrysophycean stomatocysts with long spines are described following International Statospore Working Group (ISWG) guidelines and illustrated by SEM micrographs. Differences of our new morphotypes from known stomatocysts are discussed. Their biological affinity is currently unknown.
