two-celled carpogonial branches. The 
interpretation of fig. C is difficult; 
to the left is shown what seems to 
be a three-celled carpogonial branch, 
but to the right of it two trichogynes 
are seen, the connection of which 
with carpogonial branches is doubt- 
ful. Nearly all the procarps observed 
had no well deyeloped carpogonium 
and no trace of a trichogyne. 
Procarps were observed in nearly 
all the months of March to No- 
vember, in particular from May to 
November. They thus occur partly at the same time as the nemathecia, partly 
(after May) alone. 
Any indication of a further development of the procarps, in particular from 
the auxiliary cells, was not observed, and cysto- 
carps are unknown (comp. aboye). 
As mentioned above, DARBISHIRE observed 
spermatia adhering to the trichogynes (1894, 
p- 369), but he did not describe the antheridia 
and spermatia. I have often seen what I supposed 
to be antheridia, most frequently in procarp-bearing 
specimens but I am not fully convinced of their 
sexual character. In sexual individuals the outer 
cortical cells are often disunited to a greater or 
less extent, in particular in specimens treated 
with FLEMMINGS solution, and the outer cortex 
then consists of oblong or short cells imbedded 
in a hyaline gelatinous substance. The cells are 
not very different from the ordinary cortical cells 
but often contain a very distinct nucleus, situated 
near the lower end of the cell and stained intensely 
by treatment after HEIDENHAIN; the subjacent cells 
may then be the antheridia-producing cells (spermat- 
angial mother-cells, SVEDELIUs). Comp. fig. 540 (Plate 
VIII, fig. 10). If the here described cells are really 
antheridia, the species is usually monoecious.
