- Among littoral mats of an irrigation canal in South Slovakia, long filaments of a heterocytous cyanobacterium were found that were longitudinally attached to filaments of Mougeotia sp. and the centric diatom Aulacoseira italica (Ehrenberg) Simonsen. Similar heterocytous taxa attached to other algae have been described, but without akinetes, so their life cycle is incompletely known and their taxonomic position remains unclear. The presence of a sheath and the observation of solitary akinetes allowed us to classify our specimens as a representative of the genus Aulosira Bornet et Flahault. Our study lead us to propose a new combination – Aulosira epiphytica (Gardner) Hindáková et Hindák, comb. nova, using Nodularia epiphytica Gardner 1927 as basionym.
