An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota. The name "endospore" is suggestive of a spore or seed-like form (''endo'' means 'within'), but it is not a true spore (i.e., no ...

History
The genus ''Ureibacillus'' was split from the genus '' Bacillus'' in 2001 to encompass ''Bacillus thermosphaericus'' (now ''Ureibacillus thermosphaericus'') as well as several newly discovered similar strains of bacteria.[
In 2020, multiple ''Lysinibacillus'' species were transferred into ''Ureibacillus'' based on branching patterns in various phylogenetic trees constructed based on conserved genome sequences, indicating their phylogenetic relatedness.]Caryophanaceae
The ''Caryophanaceae'' is a family of Gram-positive bacteria. In 2020, the now defunct family ''Planococcaceae'' was merged into ''Caryophanaceae'' to rectify a nomenclature anomaly. The type genus of this family is ''Caryophanon.''
The family ' ...
'' encompassed many branching anomalies such as this one, partially due to the reliance on 16S rRNA sequences as a method for classification, which is known to have low resolution power and give differing results depending on the algorithm used.
