LICHENS

The spores are similar to those of the type. The specimen from 
Fraser Reach shows also fragments of Sticta oregano,. Judging from 
the specimens submitted, this must be one of the most abundant and 
characteristic lichens of the Alaskan coast. It is noticeable that in the 
collection here listed the species does not appear north of the Aleutian 
Islands. In the northern region its place is taken by the variety 
linita , which is represented by nine specimens, only three of which 
were collected south of the Aleutian Islands, and those all at one place. 
Arnold reports it from Newfoundland but not from Alaska. Dr. Lind¬ 
say 1 says of it: “ Not in the present collection and not given at all by 
Th. Fries as a Greenland lichen. But in the Kew Herbarium I saw 
specimens of the ordinary form labeled ‘ Davis Straits.’ The labels, 
however, unfortunately did not inform us on which coast the plant was 
collected, east or west.” Fries reports it from Laj:>land, Norland, and 
the Samoyede country. Nylander records its occurrence in Scandina¬ 
via, but not its frequency. Tuckerman has recorded it for California.

Cape Nome (Setchell). All sterile. Collected by Macoun on St. 
Paul Island. It is reported from Port Clarence by Nylander. 
Nylander, in his revision of Rothrock’s list, states that Dr. Bean’s 
specimen, which is listed as Sticta pulmonaria by Rothrock, should 
be placed under this variety. This rock form is the more widely dis¬ 
tributed alpine and arctic form. 
Additional Alaska species of the genus are: Sticta limbata (Sm.) 
Ach., collected by Dr. Cooley at Sheep Creek and at Salmon Creek, 
near Juneau; and Sticta scrobiculaia (Scop.) Mass., credited by 
Rothrock to Kotzebue Sound, no collector being given.
