12 Brierlev, Life-History of Leptospiia;na LevianecB. 



Woronin states that the whole process occurs almost 

 instantaneousl}', but I have observed that the time 

 elapsing between the first and final stages of ejection 

 may vary from a few seconds to forty-eight hours. In 

 cases where a lengthy period intervened, the spores were 



1 — 3. Asci after rupture of outer envelope, containing 

 immature spores in extended inner pellicle. 



4. Ascus after final dehiscence. 



5. Transverse rupture of ascus. 



6. Ascus after simultaneous rupture of inner and outer 



envelopes. 

 7 — 8. .Spore germinating in ascus neck.
