(Hoffm.) Flk. Wainio 1 . c. p. 242. Most of the innumerable squamosa 
subdivisions of recent European proposal are as yet undetected in this 
country. To a great extent this is due to the indifference of our investi- 
gators rather than lack of material. K —

cariosa (Ach.) Spreng. f. cribosa (Wallr.) Wain. Wainio 1 . c. p. 248. In 
my copy only one podetia characteristic of the form. No. 28 N. A. L. 
Wellesley, Mass., marked by Miss Cummings as C. cariosa is with diffi- 
culty referable to the species. The primary thallus is not unlike that of 
C. cariosa , and the reaction is similar, ®but the whole habit of the podetia 
is much like that of C. strepsilis f. glabrata Wain, only larger. It is in- 
teresting to note here, that C. strepsilis has by many authors been 
referred to C. cariosa. No. 28 is distinctly atypical and irreconcilable 
with any described C. cariosa form in my copy, whatever a study of the 
the other material distributed under that number may demonstrate. K-|- 
Cladonia gracilis (L.) Willd.) v. chordalis (Flk.) Scbaer. No. 272 L. B. A. 
and No. 140 N. A. L. Mt. Moosilauke, N. H. = C amaurocraea (Flk.) 
Schaer.) celotea Ach. Wainio 1 . c. p. 232. The burden of error in this 
determination must in part rest with the late Mr. T. A. Williams. The 
original specimen submitted to Mr. Williams by Miss Cummings, 
now in my herbarium, is indorsed in the handwriting of the former, 
‘ ‘ C. gracils v. e long at a Fr. cups almost obsolete. ” It seems very odd that 
Miss Cummings should have accepted this view, for in her early New 
England Lichen series the same plant was issued as C. amaurocraea.
