Sampling date 10/2008. Scale bars indicate 50 µm (1, 2), 10 µm (3).

Three images.

First:	Vegetation cone of the red alga Leptosiphonia fibrillosa with epibionts (Cothurnia spec., a peritrich ciliate, and Licmophora juergensii, an araphid diatom). The filamentous hairs (trichoblasts) only occur near the vegetative pole and are therefore short-lived.
Second:	A more mature branch of Leptosiphonia fibrillosa with growth organisms (Licmophora juergensii , an araphid diatom and some filamentous colonies of cyanobacteria).
Third:	Zoom on the cell surface. The red tiles are the chloroplasts. The green of chlorophyll is masked by the accessory pigment phycoerythrin.
