Brodiei found in nature as could be expected under these 
conditions, and there can be no doubt of their identity. 
The germination of the spores of the nemathecia then 
shows conclusively that the latter do not belong to a para- 
site but that they represent a 
link in the development of 
Phyllophora Brodiei. 
CHEMIN has recently (1927) 
observed the germination of 
the tetraspores of another nema- 
thecium interpreted as a para- 
site, namely that of Gymnogon- 
grus norvegicus described by 
SCHMITZ as Actinococcus pellæ- 
formis (Scumitz 1893, p. 387). 
The spores sowed in glass-ves- 
sels developed basal discs which

32 months old germlings from vegicus. As ascertained by CHE- 
the walls and the bottom of the 
ee tig. 17 331 MIN, this species has distinct 
sexual and asexual individuals; 
the author has found no facts supporting the hypothesis 
of the parasitical nature of the nemathecia, and he there- 
fore considers Gymn. norvegicus as a normal diplobiontic 
Floridea. 
Conclusions. 
From what has been shown above il must be concluded 
that all individuals of Phyllophora Brodiwi are (actually or 
virtually) sexual plants and that free-living tetraspore-bearing
