Anatomy
Unusually for bacteria, the filaments of this species have an elongated base and a pointed tip with transparent hair at the end.[2] The filaments have coatings that are either firm or jelly-like, and they all are made up of concentric layers that are colored yellow or brown. The filament also grows like the root of a plant. Sometimes the filament sheds and can reproduce asexually by dropping fragments (hormogonia) off the stem.
