The novel strain produced short chains of non-motile spores on the tips of long sporophores branching from the vegetative hyphae. The morphological and chemotaxonomic properties of this new isolate corresponded to those of members of the genus Herbidospora. Furthermore, 16S rRNA gene sequence analysis showed that the strain was closely related to members of the genus Herbidospora. Phenotypic properties and DNA–DNA relatedness values differentiated the new strain from its closest phylogenetic relatives Herbidospora yilanensis 0351M-12T (35–54 % DNA–DNA relatedness) and Herbidospora daliensis 0385M-1T (58–65 % relatedness). On the basis of phenotypic, genotypic and phylogenetic data, strain DMKUA 205T could be clearly distinguished from the type strains of H. yilanensis and H. daliensis. Therefore, strain DMKUA 205T represents a novel species, for which the name Herbidospora sakaeratensis sp. nov. is proposed. The type strain is strain DMKUA 205T ( = BCC 11662T = NBRC 102641T). In addition, the DNA–DNA hybridization results from this study revealed that Streptosporangium claviforme is a later synonym of Herbidospora cretacea., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.024315-0
