King. — Cytology of Araiospora. 
PLATE 14. 
Fig. 23. Oospore showing intermingling of coarse and fine meshed cytoplasm 
Antheridium almost empty ; evidences of two degenerate nuclei 
Fertilization tube and pore shown. 
Fig. 24. Slightly older oospore. The large alveolae fewer and larger. These 
are probably filled during life with oleagenous food substances. 
Fig. 25. Oospore with thin wall formed on inside of periplasmic wall. The 
nuclei still pointed. Partially dissolved oleagenous substances 
present in the large alveolae. 
Fig. 26-27. Thicker walled, older oospores that contain nuclei which have 
beaks. 
Fig. 28. Binucleate oospore with a conspicuous wall. These nuclei are close 
together but distinct. 
Fig. 29. Binucleate old oospore cut tangentially. The nuclei here, too, are 
apparently in contact. A large globule occupies the center of 
this oospore. 
Fig. 30. Binucleate, thick walled oospore showing sharply the two walls. 
There is no central globule and the nuclei are not in contact. 
Fig. 31. Binucleate old oospore showing conspicuous central globule. The 
other nucleus appears in the next section.
