Fig. 5—A. A mature or nearly mature ascus of OpMobolus heterostrophus as obtained from a freshly 
crushed perithecium. X 476 
B. The same ascus as in A, an hour later, showing elongation presumably preliminary to 
dehiscence; and the insertion of septa in the apical portion of the spores 
C, D. Asci like B, after elongation, C containing only 2 spores. X 476 
E. Partial liberation of ascospores by rupture of ascus toward apex; evidently an instance of 
frustrated discharge. X 476 
F, G. Ascospores germinating by production of germ tubes Fa-g, Ga-f, respectively. X 476 
H, I, J, K. Ascospores in mature septate condition. X 476 
L. M. Mature ascospores inclosed in a mucous sheath. X 476
