Taxonomic remark Sergeev et al., 2012 comment further on the taxonomic position of Huroniospora (which they regard as incertae sedis in Bacteria): Huroniospora has been described by Barghoorn (Barghoorn & Tyler, 1965) who compared them to chroococcacean unicellular Chroococcus-type cyanobacteria, endospores of hormogonian blue-green algae or iron bacteria, fungus spores or dinoflagellates. The simple morphology of Huroniospora allows many interpreatation applied to these microorganism remains. Later on the unicells were compared to the budding bacteria (Hirsch, 1974; see Awramik & Barghoorn, 1977 for discussion) or even to red algae order Porphyridiales (Tappan, 1976). However, most researches consider Huroniospora as cyanobacterium consistent with their stromatolitic association and lack in non-stromatolitic facies of the Gunflint Formation (Awramik & Barghoorn, 1977; Knoll et al., 1978; Hofmann & Schopf, 1983). Nonetheless, the simple Huroniospora morphology is possibly in favor of its heterogenic composition: most spheroids are probably true cyanobacteria, other can be either cells or spores of iron bacteria and some elongated forms could turn out to be akinetes of nostocalean or stigonematalean cyanophyceae (Cloud, 1976) [details]
