Figures 2, 5, 6, 8, 10, 12, 14-16, 18, 19, 21; 1250 diameters. 
Figures 3, 4, 7, 9, 11, 13, 17, 20; 1400 diameters. 
Plate IX 
Fig. I. Longitudinal section through pyrenocarp showing three asci and 
paraphyses. 
Fig. 2. Very young ascus with primary nucleus. 
Fig. 3. Young ascus, elongated. 
Fig. 4. First division figure of primary nucleus of the ascus. 
Fig. 5. Ascus cut obliquely. Four-nucleate stage.

Plate X 
Fig. 8. Dividing figure of fourth-nucleate stage. Well-developed asters are: 
present.

Fig. 10. Dividing figure from many-nucleate ascus. 
Fig. 1 1 . Longitudinal section through ascus after last division. Nuclei beaked 
and peripherally arranged with the centers toward the ascus membrane.

outward. 
Fig. 13. Oblique longitudinal section showing the interastral zones.
