In the course of phylogenetic analyses of the taxa within the suborder , it was observed that MK27-91F2 was misplaced in the genus . After a detailed examination of nucleotide signatures in the 16S rRNA gene sequence along with the morphological and chemotaxonomic characteristics of this strain, which are different from those of all species of as well as the other genera within the suborder, it was concluded that this strain represents a new genus, for which the name gen. nov. is proposed. Pseudosporangia are produced on the aerial mycelium, the whole-cell sugar pattern consists of galactose, mannose and ribose, phosphatidylethanolamine, phosphatidylinositol and lyso-phosphatidylethanolamine are the predominant phospholipids and MK-9(H) is the predominant menaquinone. The type species of the proposed new genus is gen. nov., comb. nov., with the type strain MK27-91F2 (=NRRL B-24463 =DSM 44720 =FERM P-16053 =JCM 10302 =NBRC 16184).
