show frequent anastomoses, but these raay be found at any place where 
growth is espeeially aetive. Growth followed by nuclear and cell division 
may sometimes take place quite rapidly in the short filament connecting 
two hyphae so that it becomes divided into short cells which are isodia- 
metric or if elongated, are at most onlv a few times their width in length. 
Such a filament may bear several carpogones (Fig. 13). The cytoplasm 
in the cells of such a filament is denser and more granulär tlian that in 
the older cells of the hyphae which it conne'cts; the nnelei of tliis fila- 
ment are also very distinct and larger in proportion to the size of the 
cell. The greater density of the cytoplasm probably makes the pro- 
portion of living nuclear and cytoplasmic material abont the same as 
that in the long cells of other hyphae. From one or more of the cells 
of the filament in qnestion new branches grow out which coil at once 
and form the carpogones. 
The cells of a carpogone are exactly like those of the hypha on which 
it is borne — thin-walled, isodiametric at first and later two to three 
times as long as wide. The resemblanc-e extends also to the cell eontents. 
There are from 15 to 25 cells in such a coil. The number of spirals varies 
from 2 to about 3 1 / 2 . Sometimes the spiral is loosely and unevenly 
coiled; more often it is coiled quite evenly. The cross walls show no 
openings between adjacent cells (Fig. 13). 
Very shortly after the spirals are formed, the terminal cell begins 
to elongate. It is 3 to 5 microns wide and reaches a length of 175 to 
280 microns. This long terminal cell of a carpogone is always easily 
distinguished from the vegetative hyphae in a staincd section by its 
c-olor. It is stained more deeply blue than the other hyphae. It is some- 
times reddish if the exposure to the safranin has been prolonged, but is 
very seldom stained by the orange. This deep stain is probably due to 
a slight increase in thickness of the cell wall which appears to take the 
stain very readily. The width of the cell is also slightly greater than 
that of most of the vegetative cells, and the greater width, together with 
the deeper stain and the absenee of cross walls, makes it very conspicuous. 
Very often several of the cells next to the terminal cell are elongated 
more than those further back in the coils of the carpogone. 
Stahl has distinguished three parts in the carpogone — the reeeptive 
portion and the conductive portion which together make up the tricho- 
gyne, and the coiled ascogone from which later the ascogenous hyphae 
develop. In my material these three parts may be readily distinguished. 
The trichogyne, using Stahl’s terminology, is more than the long ter- 
minal cell. It includes also the several somewhat elongated cells below
