T. C. Frye. 
Between August 25 and 29, igo), the writer had occasion to make a trip 
to. the Mt. Hood region in Oregon, remaining for a few days in the vicinity 
of Mt. Hood post office at an altitude of about 2000 feet. From there the 
mountain was ascended to a height of 9000-10000 feet, following the trail to 
Cloud Cap Inn, and from there the ridge on the east side of Eleanor 
Glacier. A few mosses, liverworts and lichens were picked up on the trip, a 
list of which is here given.

Lecanora pallescens tumidula (Pers.) Schaer. Mt. Hood P. O. ; on bark 
of living Alnus Oregona , along rivulet.

Cladonia subsquamosa f. granulosa Wain. Mt. Hood P. O. ; on dry soil. 
Evernia vulpina(L.) Ach. Mt. Hood; on trees; at 2000 feet only in damp 
hollows, at 8000 feet almost everywhere. This is a common form in high alti- 
tudes but usually sterile ; here at high altitudes it fruited. Its yellow color 
makes it one of the most conspicuous lichens of the region.
