1909}  Riddle,— Lists of New England Plants,—XXIII. 219 
Maine" (Bull. Torrey Bot. Club 21:389). Through the courtesy of 
Prof. M. A. Chrysler, I have had an opportunity of examining the 
specimens upon which this record was based. ‘The specimens are very 
doubtfully Cl. bellidiflora, having a much stronger resemblance to 
squamulose forms of Cl. eristatella 'Tuck. Similar specimens, col- 
lected in the White Mts. by Tuckerman are in the latter's herbarium, 
marked doubtful. 
Cladonia didyma (Flke.) Wainio. (Cl. pulchella Schwein.) Re- 
corded in Rand & Redfield's “Flora of Mt. Desert Island, Maine"; 
but no specimen is to be found in Mr. Rand's herbarium, and as the 
species is distinctly southern in its distribution and is not otherwise 
known from New England, the record was probably based on an 
erroneous determination. | i 
Cladonia flabelliformis (Flke.) Wainio. Recorded by Willey in his 
«List of the Lichens of New Bedford, Mass.,” but not generally 
recognized by American students as distinct from Cl. macilenta. 
Cladonia lepidota Fr. Recorded by Willey (J. c.). This species is 
considered by Wainio to be synonymous with Cl. cristatella var. 
ochrocarpia Tuck. and the specimens are, therefore, listed under that 
name. 
Cladonia leptophylla Nyl. Recorded by Willey (l. ¢.), but included 
under Cl. mitrula Tuck. by American students. 
Cladonia pyxidata var. pocillum Ach. Recorded by Willey (l. c.). 
This is an arctic variety not otherwise known from New England, and 
this record must, therefore, be considered doubtful. 
Cladonia alpicola var. Karelica Wainio. ‘This is stated by Wainio 
to be synonymous with the true Cl. symphycarpa of Fries. It is 
recorded from New England by G. K. Merrill in Bryologist 12:46 
(1909), but no specimens examined appear to belong here, and it is, 
therefore, omitted until better known. Mr. Merrill has also, within 
the last year, segregated two new species, Cladonia multiformis (in 
Bryol. 12:1) and Cl. polycarpia (in Bryol. 12:46). It has seemed 
best, however, not to include these in the list until their status can be 
determined by further study.
