Abstract

Ten taxa of silica-scaled chrysophytes (Synurophyceae and Chrysophyceae) were found during an investigation of mires and peat bogs in the Abisko region (Swedish Lapland). The chrysophyte flora consisted mainly of acidophilic (Synura echinulata, S. sphagnicola, Chrysosphaerella longispina) or pH indifferent widely distributed taxa. Together with frequently reported taxa the rare Synura petersenii f. bjoerkii and a new species of Synura, S. obesa were found. Mallomonas corcontica was reported for the first time from Sweden. The occurrence of the species is discussed in relation to some environmental factors (particularly pH).
