Sect. 1.—CyPHELIUM, De Not. 
Cc. trichiale, Ach. On Hemlock trunks, and on decaying wood; Moun- 
tains of New England. Also on the coast (Mr. Russell, Mr. Willey). C. 
melanopheum, Ach., has not yet occurred here; the lichen rather doubt- 
fully referred to an ecrustaceous state of it in Syn. Lich. N. Eng., being 
elsewhere referable by the spores. ——C. brunneolum, Ach. On decaying 
wood, in the mountains, with the last. —— C. pheocephalum (Turn.) Turn. 
& Borr. Decaying wood, with the last. Sent also from Canada (Mr. 
Drummond) and New Bedford (Mr. Willey). —— C. chrysocephalum (Turn.) 
Ach. Hemlock trunks in the mountains of New England. Found also, 
on trunks, New Bedford (Mr. Willey). On Pinus, California (Mr. Bolan- 
der). 
Sect. 2.—Catxicium, De Not. 
C. lenticulare (Hoffm.) Ach. (Tuck. Lich. exs.n. 145. C. quercinum, 
Pers., Nyl.). Decaying wood in the mountains of New England; and 
occurring also in the v. subcimerewm, Nyl. (C. viride, Syn. N. Eng., non 
Auctt.).——C. curtum, Turn. & Borr. Old wooden fences, Manchester, 
Mass. (Oakes) and elsewhere on the coast. White Mountains. —— C. sub- 
tile, Fr. (Lich. Suec.n. 14). On dead wood. Arctic America (Hook.). 
Common in the mountains of New England; where it also occurs on the 
trunks of Hemlock and other trees, with a distinct, white thallus. Such 
a form is C. parietinum v. albonigrum, Nyl. Syn., from Oak trunks, Had- 
ley, Mass. (Myself). New York, on dead wood, (Mr. Peck). New Jersey, 
on the same (Mr. Austin). Illinois, on the same (Mr. Hall). Alabama, 
on the same (Mr. Beaumont). Texas, on the same (Mr. Ravenel). Cali- 
fornia, on the same (Dr. J. G. Cooper) and on Pinus muricata (Mr. Bolan- 
der). The small spores (averaging 0,005-8™- in length, and 0,0025- 
0,0045™™. in width) of my plants are, so far as observed, always simple ; 
and they should therefore be referable to C. parietinum, Nyl. Syn. But 
this differs in nothing beside the unilocular spores from C. pusillum, Nyl. 
Syn.; and both conditions were brought together in the same author’s 
earlier C. subtile (Nyl. Prodr. Gall.).——C. fuscipes, Tuckerm.,! distin- 
guished by its pale stipes and larger spores from the species just reckoned, 
as by the spores from C. paillescens, Nyl. Scand., has no doubt a much 
wider extension than that given below. ——C. trachelinum, Ach. On 
1 Calicium fuscipes (sp. nova) thallo obsoleto ; apotheciis turbinato-lentiformi- 
bus subtus albidis, disco convexo nigro, stipite firmo fusco. Spore in thecis cylin- 
draceis octone, ellipsoidec 1. oblongo-ellipsoidew, semper simplices, fuscescentes, 
longit. 0,009-16™™., crassit. 0,004-7™™., On dead wood (Oak rails) New Jersey 
(Mr. Austin). Canada (Mr. Drummond). Larger and stouterthan C. subtile, with 
larger spores. Apothecia exactly turbinate-lentiform, the under side, as well as 
the upper portion of the brown stipe, as if thinly white-varnished. The hymenial 
gelatine offers a feeble blue reaction with iodine.
