Murrill : Light-Colored Resupinate Polypores 79 



" Color ex albido ligneus ; pori ampli, rotundati vel angulati, 

 non flexuosi nec daedaloidei ; sporae hyalinae, cylindraceo-cur- 

 vulae, mobiles, 4X i-'iji p', hyphae contextus crassiuscule tuni-

This species attacks a variety of hosts, apparently preferring 

 pine, fir, spruce, and other conifers, in the wood of which it pro- 

 duces a brown rot. Other hosts represented in our collection 

 are : American elm, American linden, maple, oak, alder, hickory, 

 beech, white cedar, yellow birch, wild black cherry, orange, and 

 old fruit-bodies of various polypores. The following specimens 

 have been examined :

3. Poria subacida (Peck) Sacc. 



Among the larger resupinate species having thin-walled, annual 

 tubes, this species described by Peck in 1885 is very common as 

 well as very conspicuous. I have collected it in many forms, in 

 many localities, and on many different hosts, both coniferous and
