kinetically. The failure to discover the spindle may have been 
due to inadequate staining or insufficient magnification. In 
other essential details the process agrees with Harper's descrip- 
tion of karyokinesis in the Discomycetes. If the details seem 
incomplete it must be remembered that the largest nuclei meas- 
ured only five or six micromillimeters in diameter, and minute 
structure was extremely difficult to determine with the instru- 
ments available. 
The general sequence in the process of the development of 
the ascigerous fruit of Teichospora may now be summarized as 
follows : 
I. A single cell of the mycelium by successive divisions and 
growth forms a solid sphere of parenchymatous tissue. 
2. Certain of the interior cells of this tissue become enlarged 
and differentiated into asci. 
3. Each ascus contains at first a single large nucleus, which 
by successive karyokinetic divisions furnishes a single smaller 
nucleus for each compartment of the multiseptate spores. 
TEICHOSPORELLA. 
An undescribed species of Teichosporella, found by Miss 
Stoneman on oak and studied in a similar way, was found to 
develop in almost exactly the same manner as the Teichospor
