NOTES UPON THE ABOVE List 
The names adopted in the genus Cladonia are based on Wainio's 
“Monographia Cladoniarum Universalis.” In cases where the no- 
menclature of Tuckerman’s “Synopsis of North American Lichens” 
differs from that of Wainio, the Tuckerman name is given in paren- 
thesis, in these notes, following the Wainio name. On one point only 
does the usage here followed depart from that of Wainio. In his 
Monograph, he has distributed all the forms of polymorphie species 
under varietal names, making, therefore, a compound conception of 
the species. This is a practice not followed in other groups of plants 
and apparently unnecessary. In this list the specific name is under- 
stood to stand for the typical form of the species, and is equivalent to 
the first variety given under each species by Wainio. This is liable 
to lead to confusion only in the following species: Cladonia fimbriata, 
furcata, and gracilis. For the synonymy, reference may be made to 
the notes on these species given below. 
Baeomyces ericetorum (L.) Wainio. (B. aeruginosus (Scop.) DEJ 
There is considerable doubt as to the true relationships of this species, 
but it has seemed best in this list to retain it in its traditional position, 
using, however, the earlier name. (Compare Wainio: Notulae de 
synonymia lichenum, in Medd. Soc. pro Fauna et Flora fennica, vol. 
14, 1886.) 
Cladonia alpestris (L.) Rabenh. (Cl. rangiferina var. alpestris 
(L.) Schaer.) 
Cladonia bacillaris Nyl. (Cl. macilenta (Ehrh.) Hoffm. in part.) 
Cladonia cariosa var. corticata Wainio. (Cl. symphycarpa, in part, 
of American authors, not Fries.) Compare Fink in Bryologist 9:23 
(1906). 
Cladonia coccifera (L.) Willd. (Cl. cornucopioides (L.) Fr) 
Cladonia crispata (Ach.) Flot.. (Cl. furcata var. crispata Flke.) 
Cladonia fimbriata (L.) Fr. Under the specific name is included 
material called “var. simplex” by Wainio, "var. tubae ormis Fr." 
by Tuckerman, in part. ‘Tuckerman’s “var. tubaeformis” also in- 
cluded what is here called “var. coniocrea (Flke.) Wain."; and his 
“var. radiata Fr.” included the remaining three varieties of this list. 
Cladonia foliacea var. aleicornis (Lightf.) Schaer. (Cl. alcicornis 
(Lightf.) Еке.) The Maine record is based on Rand & Redfield’s 
“Flora of Mt. Desert Island." Through the courtesy of Mr. E. L.
