This beautiful genus is, I believe, new to our United 
States Flora. There is one other form, growing with 
these in Europe, which may probably be — at the 
White Mountains. 
Crapowi,, Hoffm. In adopting an arrangement. for 
such lichens of this group as were in my herbarium, 1 
found some difficulty in ascertaining which had the best 
authority. Acharius, after separating the Boeomyces, 
which in the Methodus he had confounded with the true 
Cladóniz, arranged these last as one genus under the 
name Cenomyce. Latterly, Hooker, following M. Feé, 
has distinguished those whose type is C. rangiferina 
from those whose type is C. pyxidata, calling the former 
Cladónia and the latter Scyphóphorus ; ; (the Scy- 
phíphorus of Vent. Tabl. du Regne Veg. 2, 36.) On 
the other hand, Scherer and Sprengel, admitting but 
one genus, arrange their species under the old name 
Cladénia, of Hoffmann, which was prior to Acharius's 
Cenomyce. This appeared most accordant with the 
canons of the science, and I: may | be permitted to.add, 
most natural. The apothecia are the. same in both of 
the new genera ; and the only differences consist in the 
general absence of the thallus, and the subulate-branched 
podetia in the Cladoniz ; and the general presence of a
