In this family the number of septa in the sporidia, at different 

 stages ftf their growth, is unusually variable; the color also run.s from 

 hyaline, through various shades of brown, so that these two eharactei's, 

 uuaccomijanied as they ai-e, by any distinctive* vegetative peculiariti<!s.

 A- Cooke, in reducin ;• I.ophioKpha'ra and Lophiotrema to mere sub- 

 genera.
