III. A LIST OF THE LICHENS OF WASHINGTON AND

VICINITY.

By Rev. E. LEHNERT.

[This great desideratum, a list of our Lichens, is at last supplied, through the indefatigable labors of Mr. Lehnert, who has also placed it at my disposal.

In a prefatory note accompanying the list, Mr. Lehnert says: “So far as known, the Lichens of the District comprise 251 species, with 89 varieties, a total of 340 forms. In the main our species are not as showy as those from the North or South, but have, when compared with the same species from these localities, a dwarfed and depauperate aspect, caused, possibly, by the dryness of our climate, as we have very warm summers and cold winters ").
