straighter course than is usual with these threads, and hence its 
relation to the coil is rendered very obvious. The generative hypha 
is more deeply stained than the surrounding vegetative threads, 
while the procarp coil itself is quite opaque. Figs. 32-35 represent 
other procarp bodies at approximately the same stage of develop- 
ment as that of fig. 11. Most of these figures are taken from sec- 
tions cut longitudinally through the ascocarp, but fig. 34 represents 
portions of a procarp found in two contiguous sections of a series 
taken in a transverse plane. These illustrations give some idea 
of the diversity of form displayed by these structures. They vary 
from an almost straight, slightly twisted series of cells, to coils 
such as that of fig. 11. These illustrations also show the relation- 
ships of the procarps and trichogynes. This relationship is evident 
in fig. 6. Two procarps and their trichogynes appearing in this 
section are shown enlarged in fig. 8, where, however, on account of 
the thickness of the section and the meandering habit of the threads 
of the procarp and trichogynes, not all of these structures can be 
obtained in sharp focus at the same time. The protrusion of the 
trichogyne from the surface of the ascocarp is shown well in fig. 13, 
which is the first section of a series through the cap of an ascocarp 
at this stage. The exposed tip of a trichogyne, cut off with the 
first section, is clearly shown, several of its cells being visible. 
No structures have been found that could be regarded as sper- 
mogonia, and no bodies that correspond to spermatia. Furthermore, 
the writer has no evidence that the trichogynes functioned in any 
way, and since they disappear very soon, is inclined to regard them 
as vestigial organs in Cudonia. 
As may be seen from the illustrations, the procarps are very 
deeply staining bodies, and in their earlier stages it is impossible 
to differentiate them cytologically. Nevertheless here and there 
an occasional cell may be seen to contain what is doubtless a single 
nucleus, while a smaller number contain two (figs. 32-35). Thus what 
slight evidence there is points to the original condition of these 
bodies as being uninucleate. A little later on, however, they become 
multinucleate. This takes place soon after the appearance of the 
paraphyses, and is preceded by the disappearance of the tricho- 
gynes. At this stage the remaining cells of the procarps become
