Sept. 1919.] THE GERMINATION AND DEVELOPMENT. \ 83 



I do not know how the vegetation of Phyllitis is on the 

 coast about Naples where Reinke collected his material and 

 tried his experiment. If the sporelings of the Phyllitis fronds 

 are formed in nature thereabout in 6—8 weeks after the libera- 

 tion 6f the zoospores from the sori, the non-appearing season 

 of Phyllitis at Naples must be shorter than a few months. On 

 our coasts, as mentioned before, there is about a half-year period 

 during which we can not find any healthy frond of Phyllitis 

 Fascia KuTZ. -* 



About the germinations of Scytosiphon and Asperococcus, 

 Reinke^'' states similar things as he did about Phyllitis except the 

 formation of the " secondary spores." His report is, therefore, 

 to be understood to conclude that there is onh' one asexual 

 mode of propagation in the Encoeliaceous members, onlj' in 

 Phyllitis there occurs at the same time a peculiar mode of 

 formation of spores which recalls the chlamidospore of certain 

 fungus.
