54 The Botanical Gazette. [February, 
In connection with the general habit of Sapromyces it may 
be noted that Reinsch in his first description, 7 where his sub- 
sequent ‘‘Naegelia species 11” is described and figured as 
‘‘Hyphomycetarum nov. gen.” represents the sporangiferous 
hyphe as arising at intervals froma ‘‘stroma ex filis tenui- 
- oribus elongatis subramosis inter muscos aquaticos intricatis 
formatum,” but no reference to this mode of growth is made 
in his second paper; and since no such habit was observed by 
the writer, the account just quoted is presumably of doubtful 
accuracy. : 
That the species under consideration is not identical with 
R. interruptum, as asserted by Cornu, seems sufficiently mani- 
fest, since it lacks the highly differentiated basal cell, its spo- 
rangiaare verticillate and its oospores are nearly smooth; while 
the receptive portion of the oogonium is always terminal, not 
‘‘vers la base.”® The close resemblances between the sexual 
organs and their action in the two genera is certainly striking: 
yet until further data are obtained concerning these phenom- 
ena in other genera of the sub-family, it seems not unrea- 
sonable to assume that they may have a more than generic 
significance. ® 
The form may be briefly characterized as follows:
