Acholeplasmataceae [SEP] parent taxon
Acholeplasmataceae
The Acholeplasmatales are an order in the class Mollicutes, containing only one family, Acholeplasmataceae, comprising the genera "Acholeplasma" and "Phytoplasma". Yet, "Phytoplasma" has the candidatus state, because members still could not be cultured.
Etymology: The name Acholeplasmatales is derived from the Greek "a" = not, "cholè" = bile and "plasma" = anything moulded or formed.
Species in the order Acholeplasmatales can grow in a medium without cholesterol, unlike species in the order Mycoplasmatales
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
