According to Touzel et al. (1988), this species is a later heterotypic synonym of Methanothrixsoehngenii Huser et al. 1983.Publication:

Methanosaeta concilii (Patel 1985) Patel and Sprott 1990 is illegitimate, because the genus name is illegitimate.Publication:

The type strain of Methanothrix soehngenii Huser et al. 1983 (the type species of the genus Methanothrix Huser et al. 1983) is contaminated by two morphologically distinct bacteria. According to the "old Rule 31a" (i.e. before January 2001) Methanothrix soehngenii was invalid. Consequently, the genus Methanothrix did not have nomenclatural standing. Since the genus Methanothrix was invalid, so were all of the species placed in the genus. Therefore, Patel and Sprott 1990 proposed that type strain GP6 of Methanothrix concilii, an axenic mesophilic isolate, be named Methanosaeta concilii (Patel 1985) Patel and Sprott 1990.Publication:
