The apothecia are innate with a thin margin which soon disappears; the disk is a reddish brown. Nephroma arcticum (L.) Fr. Thallus usually large and smooth, with rounded lobes, the edges of which are folded or rolled over onto the upper side ; when fresh it it straw-colored with a greenish shade, when dry it is a decided straw color. On the under side the margin of the thallus is an apricot color, soon turning almost black, it is covered, except at the margin, with a short, thick, nap of interlaced fibrils. The apothecia are not frequent, they are large, and affixed to the lobes of the lower side of the thallus: the disk is an orange red. N. arcticum, as its specific name indicates, is an arctic species, and is found on rocks with moss or on trunks of trees, sometimes on earth, growing with moss. Prof, Peck, the State Botanist of New York, collected this species on Pitchoff Mountain in the Adirondacks : so far this is the only known station in the Fig. I. A^, tomentosmn. Nephroma tomentosum (Hoff.) Koerb. Fig. i. Thallus quite large, in some specimens very large, with rounded lobes, the margins of which are wavy, and usually more or less tomentose. The color is glaucous or green- ish brown, becoming lead color or dark russet. The under side is paler, usually somewhat tomentose, and covered with groups of minute, smooth, pale tubercles, toward the center are short, stiff fibrils b}^ which it is.
