(2000) found the granulocytes of Ostrea edulis contained only numerous basophilic or refringent
cytoplasmic granules, in agreement with our study on the staining characteristic of C.
Basidiospores (n = 64/8) 8.6-12.6 X 2.9-4.0 [micro]m (E = 2.36-3.78; Em = 3.02; Lm = 10.68 [micro]m), elongate comma-shaped, elongate teardrop-shaped or boletoid, smooth, thin-walled, hyaline; contents usually homogeneous or with 1-several refringent
guttules; hilar appendix curved, broad, not prominent.
In both autozooid and siphonozooid polyps, photocytes are clustered in specific locations of the endodermal layer where cells filled with highly refringent granules (presumably acting as diffuse reflectors for the light emission) predominate (Anctil et al., 1984; Awad and Anctil, 1994).
Occasionally, however, cells containing refringent granules appeared to be associated with punctate immunoreactivity at their boundaries [ILLUSTRATION FOR FIGURE 6A OMITTED].
The cells showed an apparent increase in size, diffuse cell rounding, and a refringent
aspect (Figure 1B).
