234 J- Ramsbottom, Some recent work on the cytology of fungus reproduction, II 
Mucorineae, and also the resemblances in the method of spore formation. 
He regards the swelling which afterwards becomes the zygote, into which 
the fused male and female nuclei pass, as being possibly analogous to 
an ascogenous hypha. The development of vegetative hyphae round the 
zygote also recalls the Ascomycetes. 
It is interesting to find in this genus such differences from the 
ordinary Phycomycete type of sexual process. Whether they are to be 
regarded as being anything more than adaptations to a subterranean mode 
of existence seems doubtful. In any case, the Phycomycetes apparently 
have their hypogeal section as well as th e Ascomycetes and Basidiomycetes.
