Carolina, resembles not a little, in its apothecia, A. Bolanderi ; and adds 
another member to this interesting section of Acolium. The American 
plant is closely related to A. ocellatum (Flot.) Koerb. (Anz. Lich. Lang. 
n. 211) as is that to 4. tympanellum ; but surely no lichenist would ven- 
ture to dispute the distinctness of the first-named from the last. A. tym- 
panellum is here confined to the Pacific coast. ——A. tympanellum (Ach.) 
De Not. On dead wood, Yosemite valley, California (H. Mann). One of 
a few lichens of the eastern hemisphere which are unknown in North 
America except at the extreme west.—— A. chloroconium, Tuckerm. 
(Lich. Calif. p. 28). On living Quercus agrifolia; coast of California 
(Mr. Bolander). Apothecia small, measuring 0™™, 5-0™™-, 6, in diameter. 
Spores bilocular, 0,007-12™™ long, and 0,005-6™"- wide. There is some 
evidence of an imperfect, blue reaction of the hymenial gelatine with 
iodine. —— A. viridulum (Scher.) De Not. On Red Pine, Vermont (Mr. 
Russell). On Hemlock Spruce, New Hampshire (Mr. Willey). A. tigil- 
lare (Ach.) De Not. On dead wood, common in New England. Arctic 
America (Richardson). New York (Halsey). New Jersey (Mr. Austin). 
Illinois (Mr. Hall).—— A. Javanicum (Mont & V.d.B.) Stizenb. On 
logs of Bald Cypress (Taxodium) Louisiana (Hale).

ellipsoidee, biloculares, fusce, longit. 0,012-18™™-, crassit. 0,007-9™™- On old 
logs of Cedar, Bluffton, South Carolina (Dr. J. H. Mellichamp). There is no trace 
of a margin externally, and the brownish-black walls of the proper exciple often 
do not extend upward beyond the white layer. This white layer — for the most 
part more or less straight, or a little concave —is now and then indeed (as seen in 
section) distinctly convex, precluding any regular extension of the exciple upwards, 
and giving to the thick hypothecium (as also noticed above in a similar deforma- 
tion of 4. Bolanderi) something of the peculiar outline of that of Spherophorus. 
In this new Acolium some slight blue reaction of the hymenial gelatine with 
iodine is sufficiently evident.
