MONTANA FOREST TREE FUNGI— I. 

 POLYPORACEAE 



James R. Weir 



(With Plate 6) 



Since September, 191 1, the writer has been collecting the forest' 

 tree fungi of Montana with the view of issuing a list covering all 

 species of importance found in the state. Each year's collecting 

 has resulted in finding such a large number of species that it 

 seems advisable to issue a first report confined to the Poly- 

 poraceae. 



The forest tree fungi of Montana are not very well known. 

 The earlier collectors paid little attention to this particular class 

 of plants. A few of the most important publications dealing with 

 Montana fungi may be enumerated. A list of fungi published by 

 Seymour 1 contains 52 species from Montana. Of these 8 were 

 fungi of forest trees. Kelsey 2 collecting in the vicinity of Helena 

 published a list of 74 species, of which about 14 are found on 

 leaves or twigs of forest trees. The same author 3 published notes 

 on nine species of Erysipheae of which 3 are on forest trees. 

 Anderson 4 published a series of papers on the fungi of Montana
