Morphology<\/h2>\n

Trichomes solitary or forming fine mats. Trichomes typically straight or curved, less commonly wavy; usually fairly short, consisting of a small number of cells, or (uncommonly) long, with many cells; usually conspicuously constricted at crosswalls; without firm sheaths, but may have wide, diffluent mucilaginous envelopes. Immotile or facultatively with slow gliding movement. Cells mostly cylindrical with rounded ends, or sometimes nearly barrel-shaped; almost always longer than wide, rarely almost isodiametric; apical cells cylindrical with rounded ends in typical Pseudanabaena<\/em>, or pointed in subgenera Ilyonema<\/em> and Skujanema<\/em>. One or two polar (near crosswalls) aerotopes may be present, though such species may eventually be classified into a separate genus.<\/p>\n

Ecology<\/h2>\n

Recorded from a variety of habitat types: planktic, metaphytic, periphytic, and benthic in various waters; on soils; endogloeic; and in thermal and mineral springs.<\/p>\n
