132 The Mountaineer 



127. Mnium venustum Mitt. 



E, sea level to Camp Elkhorn, 2000 feet, on 

 soil and trees in river bottom, ( Nos. 577, 596, 

 598). 



RHIZOGONIACKAE 



128. Rhisogonimn menziesii (Muell.) Mnium men- 



ziesii Muell. 



E, in bottom, about 5 miles above the mouth 

 of Lilliam Creek, on rotten log, 1800 feet, 

 (No. 488). This is a common moss on logs in 

 very damp woods, in the low altitudes of west- 

 ern Washington. I have heard it popularly 

 called the palm-tree moss. 



AULACOMNIACEAE 



129. Aulacomnium androgynum (L.) Schwaegr. 



E, on logs in woods in drier regions, from 

 Port Angeles to Humes, sea-level to 1000 feet. 

 This is a very common low altitude moss, and 

 is by far the most common bearing gemmae. 



BARTRAMIACEAE 



*130. Bartramia itliyphylla (Hall) Brid. 



E, along west fork west of Mountaineers' 

 Camp, 5500 feet, on soil among rocks of talus 

 slope, (No. 505). Q, H, 5500 feet, on wet 

 rocks, (No. 579). 



*131. Philonotis fontana Brid. 



E, (Nos. 471, 485, 500, 626), and O, 

 (No. 565) ; 2500-5500 feet, along borders of 

 alpine riverluts. This is one of the most 

 conspicuous mosses of these altitudes. It is 

 light green, and often marks the course of 

 riverlets by its light color so they can be 

 traced through the grass at a distance of ap- 

 proximately a hundred yards. 



POLYTRICHACEAE 



*132. Catharinca undulata (L.) W. & M. 



E, near the mouth of Godkin Creek, 2300 feet.
