FURTHER NOTES ON CLADONIAS. X. 
Cladonia decorticata and Cladonia degenerans. 
Bruce Fink. 
As to the relationships of Cladonia decorticata, it has been considered a 
variety of Cladonia pyxidata , to be considered in the next paper of this 
series and has also been placed as a variety of Cladonia pityrea. From 
material in the writer’s herbarium, it is apparent enough that specimens 
might easily be confused with little-branched and decorticate conditions of 
Cladonia squamosa as well as with some conditions of Cladonia furcata 
scabriuscula. It seems to the writer that, of the species considered in this 
series, the nearest relationship is with Cladonia squamosa, though Dr. 
Wainio h'as placed several of the other species already considered or to fol- 
low in the series between. The relationship with Cladonia furcata scabrius- 
cula, especially its less branched and more decorticate forms, seems quite 
near, while that with Cladonia pityrea is not at all close. ' Examination of 
an excellent series of European specimens of Cladonia pityrea , received 
from L. Scriba, reveals a closer relationship than the last, and yet it does not 
appear that Cladonia decorticata should be confused with Cladonia pityrea.
