3/9/04
culture started 2/18/04 - grey chamber, 14:10 L:D  WH medium
 
Cells mostly in clumps on the bottom of the flask.  Spherical cells with many refractile granules, often in motion.  Orange body in many cells, even smallest cells.   The orange body is granular and irregular shaped, not globular as in some other eustigs. The maximum cell size is much greater than other Nannochloropsis isolates, over 10 um.  Pappila not seen.

Culture somewhat old.  This isolate seems to grow more slowly than other Nannochloropsis and has a different growth form.

Zoospores observed - not Nannochloropsis
