in the fragment here offered. Criticism or revision of published exsiccatae is 
attended with some risk, for it is well known that exsiccati frequently fur- 
nish variable lexhibits under the same number or name. There is every 
reason to believe that diversity of this sort may be found in both the Cum- 
mings’ series, indeed it could scarcely be otherwise, determined as they were 
on Tuckerman’s phytographical conceptions. I am able to state however, 
from having in my possession many of what may be called the type exam- 
ples of the various Cladonia numbers, such being the material made use of 
by Miss Cummings and Mr. Williams in their examinations for and discus- 
sions of identifications, that there is marked agreement with the material 
published.
