Ultrastructure of Lu. migonei SG. Panels a through e are showing, respectively, the cell types I through V. Details of two secretory type II cells separating from each are shown in panel f (arrows). Panels g and h are enlarged images of the secretory cell surfaces, respectively, of the cells types III and II, showing aspects of cytoplasmic projections on their surfaces (arrowheads) and secretory vesicles (V). Scale-bars: a, b, e, 2.5 µm; c, 2.0 µm; d, f, 1.5 µm; g, h, 1.0 µm
