^aSummary of IEM labeling of wild-type 630 spores; weak, less than 50% spores labeled, 0 to 1 particles/spore section; strong, more than 75% spores labeled, up to 10 particles/spore section.

^bBulk, bulk-like material unattached to the spore (see Fig. 6C); SLM, sheet-like material unattached to the spore (see Fig. 6D).
