It is difficult to decide whether or not Reinsch's Naegelia sp. "II," 

 earlier (1875) called Hyphomycetarum, n. gen., belongs here, but, as 

 Minden suggests, it may be a depauperate form of Sapromyces elongatus. 

 Since no sex organs were found in Reinsch's material, his fungus may 

 have been the less common S. androgynus, and the same is true also of 

 Couch's and Matthews' records. However, from Reinsch's figures (pi. 

 15, figs. 7-1 1) it appears more likely his species was actually based on 

 fragments of a Rhipidium. 



Coker and Matthews (1937: 62) adopted the binomial Sapromyces 

 elongatus (Cornu) Coker for this species. There is much to be said for 

 the change, since the oospore described by Cornu for his Rhipidium 

 elongation possessed an undulate wall. Two things, however, might be 

 noted against the adoption of Cornu's name: (a) the absence in this 

 species of a well-developed basal cell, the presence of which in Cornu's 

 fungus is implied by his placing it in Rhipidium, (b) the lack of a figure 

 by Cornu and his identification of the figures of Reinsch with those of 

 his own R. interruptum (not R. elongation). The facts do not seem to be 

 conclusive for either name.
