1 Bseomyces, Ach. Meth., Cenomyce, Ach. Lich.,Cladonia, Floerk., & Fries. 

 Discovered on the coast of Oregon by Menzies ! 1787, and since found on the 

 Rocky Mountains by Douglas! and Scouler! My specimens are from the dis- 

 coverer, and Sir W. J. Hooker. We have a very nearly allied lichen in New 

 England. I have another apparently undescribed species from Mr. Lambert's 

 herbarium, which was, it would seem, collected by Mr. L. Goulding, but the 

 station is not given: S. sphoerophor aides, Tuck. Ms. : podetiis laxis teretibus 

 subsimplicibus, squamulis fibrillosis pulcherrime sphaerophoroideo-ramosis ; 

 apoth. sparsis minusculis.
