36. — Collema pulposum (Bernh.) Ach. — 



37. — Leptogium lacerum (Sw.) S. F. Gray — Our material seems to 

 be a variety of this species, wliich is new to Alaska. Port Alice, Heceta 

 Island; Deweyville, Prince of Wales Island. 



38. — Leptogium lacerum pulvinatum (Hoffm.) Nyl. — Growing on 

 mosses over rocks, at Howkan. New to Alaska. 



39. — Leptogium palmatum (Huds.) Mont- — This interesting Europ- 

 ean species which has only been found on the Pacific coast of North 

 America, from Southern California northward, has not been reported 

 from Alaska heretofore. The expedition obtained specimens from Egg 

 Harbor on Coronation Island; on East Sound, in the Kashevarof group; 

 and at Swanson Bay, B. C, At Howkan were found specimens of the 

 species which were sterile and non-typical. 



40. — Parmeliella triptophylla (Ach.) jMiill. Arg. — I find no previous 

 record of this lichen from Alaska, tho it seems to be abundant among the 

 Alaskan Islands. It occurs on rotten wood at Deweyville, Prince of Wales 

 Island; Port Alice, Heceta Island; Nichols Bay; and Coronation Island. 

 On Kuiu Island it was found on the bark of alders. Material from 

 Nichols Bay, growing on rocks and moss, yields spores 8 to 10 by 13.6 to 

 20 mikrons, the thecium deep blue with Iodine.

 at Augustine Bay, Dall Island; and Aats Bay, Coronation Island. New
