Chamaesiphon (ca-may-sigh-phon) (also known as Entophysalis) elongate cyanobacterium with spores forming at the distal end, basal part with mucus sheath. Found as one of several cyanobacterial epibionts on the leaves of the moss Hygrohypnum, a site which seems to be a focus for nitrogen fixation. Differential interference contrast.
