Coker: Two New Species of Water Molds

details, not in all. The sporangial variations cited do not look like 
the sporangia of the genera in question and neither do the spores 
within them ; and no one familiar with these genera would be 
misled into placing them there unless one’s attention be focused 
on the wording of keys rather than on the plants themselves. 
Such variations as these do not create doubt, as Lechmere implies, 
on the validity of the presently accepted classification of the 
Saprolegniaceae. The occasional appearance of a soft-shelled egg 
in a hen’s nest does not shake our faith in the reality of the dis- 
tinction between a hen and a lizard. 
Unless it be Achlya paradoxa, I know of no species whose genus 
could be in doubt after an adequate study of its asexual reproduc- 
tion alone.
