These organisms developed on slides immersed in the waters; they have not been cultivated in the laboratory. They consist of non-branching, non-septate filaments with a head at one end consisting of a cluster of round bodies. The filaments often become interlaced and form strings which can just be seen by the naked eye. They may or may not be contained in a sheath. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-20-1-1
