that the cell rising from the germinating spore is not different from the cells 
which it produces. To judge from the figures of Borner and THURET the spor- 
angia become a little larger in 
Ch. corymbifera than in Ch. 
Nemalionis, namely up to 22 u 
long. It is interesting that this 
species hitherto only known 
from the Mediterranean and 
the Gulf of Gascony has been 
found in the Limfjord, a water 
with relatively high salinity 
and summer temperature.

The greater part of the 
frond of this species grows in 
the thick outer wall of the 
Bryozoan Alcyonidium gelati- 
nosum. The endozoic filaments 
are dichotomously branched 
and give off numerous free, 
short, branched fertile fila- 
ments bearing monosporangia.

of the chromatophore. The sporangia were 13,5—17 y long, 9—10 4 broad.
