FIG. 3.

The photomicrographs are selected examples of cultures of the various types included in Fig. 1A. Only type 1B illustrates the morphology of a typical C. merolae cell. The spherical cells in different images illustrate the typical morphology of Galdieria. However, the images of Japan types IIIB and IIIC and New Zealand (NZ) type V indicate cells that are somewhat oblong. The type of division for these three strains remains undetermined. CCMEE culture numbers for the types indicated in the panel are as follows: 5508 (A), 5610 (B), 5573 (C), 5665 (D), 5664 (E), 5680 (F), 5706 (G), 5704 (H), and 5713 (I).
