    Sixty-two North American populations of seven previously described species belonging to Batrachospermum sect. Batrachospermum were examined and compared with appropriate type specimens using morphometrics and image analysis. All populations were similar to the respective type specimens in qualitative and quantitative characteristics, but the range of some morphological features has been extended. B. boryanum was the most abundant and widespread species, being collected in 34 stream sites from Newfoundland and British Columbia in the north to Georgia in the south. The other six species — B. anatinum, B. arcuatum, B. confusum, B. heterocorticum, B. pulchrum and B. skujae — were more localized and occurred in six or fewer streams. B. anatinum was restricted to Missouri, Arkansas and Virginia and B. arcuatum was collected in western North America from Alaska to Mexico. The distribution of B. confusum was disjunct, with populations occurring in Alberta, Quebec, Newfoundland, Maine and Missouri. B. heterocorticum was concentrated in the southern United States. This work represents only the second report of B. pulchrum ; all known specimens have been collected in the Lesser Antilles of the Caribbean Islands. B. skujae was sampled in tundra streams from Manitoba and Greenland and two streams in the western coniferous forest from Colorado. No new populations were found of B. carpocontortum , which was first described from two streams in Washington state. Worldwide, many of these species have been reported from Europe, but seldom from other continents.
