Taxonomic remark Sergeev et al., 2012 consider this as a form genus potentially encompassing more than Chroococcales. These authors state: "The genus Myxococcoides was established by Schopf (1968) for colonial simple spherical microfossils without organic inclusions. Schopf (1968) interpreted his Bitter Springs populations as chroococcacean cyanobacteria. With the subsequent discoveries of abundant populations in many Proterozoic cherts, Myxococcoides is considered to be a form genus encompassing microfossils of heterogeneous origin (Green et al., 1989; Knoll et al., 1991; Butterfield et al., 1994; Sergeev et al., 1995). Some species of Myxococcoides may belong to the cyanobacterial family Chroococcaceae, although this is by no means clear for the type population of M. minor (Knoll, 1982). Others closely resemble chlorococcalean green algae (Green et al., 1989; Knoll et al., 1991), while still others, including Myxococcoides grandis, may be akinetes produced by nostocalean cyanobacteria (Sergeev et al., 1995) or the empty envelopes of colonial microorganisms (Fairchild, 1985; Sergeev, 1992 a, b, 1994)." Sergeev & Schopf, 2010 place this genus under incertae sedis, ?Chroococcales or ?Chlorococcales. [details]
