lady somewhat branched; below, like the squamules, pale- 

 greenish, becoming above finely hoary-powdery ; cups obsolete ; 

 apothecia conglomerate and confluent ; scarlet (or now yellow, 



b, ochrocarpia). Fr. L. E. p. 240. Tuck. Syn. N. E. p. 55; 



& Lich. Amer. exs. n. 134. Nyl. Syn. p. 223. 



On rotten wood, as also on the earth, and rocks ; northern 

 and middle States, Muhlenberg Catal 1818. Ohio, Miss Biddle- 

 come. Illinois, Hall. Wisconsin, Lapham. South Carolina, 

 Eavenel. Alabama, Beaumont. ft, White Mountains, Tucker- 

 man. A rock-form otherwise referable here has yet the char- 

 acter of the very uncertain C. Floerkiana, Fr. ; but I cannot 

 attempt to separate specifically from C. macilenta what only 

 differs from it in the epidermis continuing throughout, for the 

 most part, smooth and entire. Indeed Fries himself did not 

 escape confounding the two; his Lich. Suec. n. 52 (C. maci- 

 lenta, Fr.) consisting, in my copy, all but wholly of C. Floerkiana 

 which it is admitted to be in part by Dr. Th. Fries (Scand. 

 p. 66). 



2S(b). C.pulchella, Schweiu. ; thallus conspicuous, the squam- 

 ules at length elongated and dissected ; podetia short, slender, 

 denudate, granulose; besprinkled and finally imbricated with 

 pale-green, and glaucescent squamules ; cups obsolete ; apothe- 

 cia as in the last preceding. Tuckerm. Suppl. 1, /. c. p. 427. 



Roots of trees, and decaying wood, North Carolina (Schwein- 

 itz), Tuckerman/. c. 1858. South Carolina, and Georgia, Eavenel. 

 Florida, Chapman. Alabama, Beaumont. Louisiana, Hale. Texas, 



Wright. Not a little resembling C. bellidiflora in miniature ; 



but the more granulose states related, through C. muscigena, 

 Eschw. (Lich. Cub. n. 42) to C. macilenta. Fries (L. E. p. 232) 

 has indicated the analogy of the lichen to such forms as C. de- 

 licata. 



29. C. Eavenelii, Tuckerm. ; thallus sub-squamulose, the 

 squamules very minute, from rounded and sub-entire becoming 

 erose-laciuulate, or more commonly disappearing in granules, 

 white ; podetia small ; short-turbinate ; simple ; smooth becom- 

 ing granulate- verrucose, and granulose; from yellowish-green 

 white; cups dilated, cyathiform, palmately proliferous; apothe- 

 cia scarlet. 



On dead wood, South Carolina, and Florida, H. W. Eavenel, 

 Esq. Also in the island of Cuba, Wright. Comparable, as
