does not mention their shape. The photograph further shows, 
at a higher level, in particular to the right, groups of darker 
cells which might possibly be identical with the generative 
cells mentioned above and their derivates. 
In examining the germination of the monospores, CHEMIN 
observed the first stages of the young plants which I have 
not seen. He found that the germinating spore produced 
a short articulate cell-filament giving rise at its distal end 
to a disc which after two weeks might consist of some 
twenty cells. Though the smallest discs observed by me 
were only slightly larger than these, I have not observed 
any trace of such a germinating filament. The rare hyaline 
hairs observed in my cultures have nothing in common 
with it. It is remarkable that CHEMIN did not meet with 
any trace of chromatophores or phycoerythrine in the spores, 
while I found a distinct yellowish chromatophore. After one 
month the greatest discs measured 40 x in diameter and 
were thicker in the middle than at the border. After two 
months the discs were only slightly more developed but 
they had multiplied by proliferation. CHEMIN concludes that 
the discs are probably the beginning of Ahnfeltia.
