92. Fomes roseus (A. & S.) Cooke. 



On Abies grandis, Corvallis. March. Rare. No. 1908. 

 I have seen but one specimen which I can refer to this species. This 

 was definitely perennial, and ungulate with a black surface. 



93. Polyporns arcularhis (Batsch) Fries. 



On oak wood, Corvallis. August. Infrequent. Nos. 1987, 1989. Not 

 previously reported from the Pacific coast. 



94. Polyporus chioneus Fries. 



On oak and maple, Corvallis. October. Infrequent. Nos. 1753, 1974. 

 One of these numbers was referred to P. trabeus Fries by Mr. Lloy3, 

 but it surely differs but little from P. chioneus. 



95. Polyporus dryadeus (Pers.) Fries. 



On Acer macrophyllum and Abies grandis, Mary's Peak and Cascadia, 

 respectively. September. Not infrequent. Nos. 1765, 2061. The dozen 

 or more applanate fructifications on maple were on a dead stub but the 

 one obtuse specimen on Abies was on a living tree. Although usually re- 

 ported as found on living oak this species of late has been reported on 

 a variety of hosts. 



96. Polyporus floriformts Quel. 



On decayed maple, Corvallis. October. Infrequent. No. 2019. Al- 

 though this species usually has an attenuate or lateral stem-like base my 

 specimens were sessile. To my knowledge this form has not been re- 

 ported from west of Wisconsin. 



97. Polyporus fragilis Fries. 



On Abies grandis, Corvallis. October. Infrequent. No. 2016. This 

 plant is white at.first as usual in this species but when touched it changes 

 to livid pink or flesh-colored when dried or brick-red when a bruised 

 portion is dried. The spores are alantoid, 1-1.5 x 5 



98. Polyporus galactinus Berk. 



On prune, Riddle, Douglas County. November, Infrequent. No. 

 1792. 



99. Polyporus hirsutulus Schw. 



On sweet cherry, Corvallis. April and May. Frequent. Nos. 1933. 

 1934, 1937- 



This form has not been reported from~west of Missouri but it perhaps 

 occurs wherever P. versicolor (L.) Fries is found, for it is probably a 

 segregate of that species. 



100. Polyporus hirtus Quel. 



On ground, Powers. October. Infrequent. No. 2040. 



1 01. Polyporus Macounii Lloyd. 



On maple, Corvallis. October. Frequent. No. 2054. Perhaps an- 

 other segregate of P. versicolor. 



102. Polyporus picipes Fries var. castaneus Lloyd. 



On maple log, Mary's Peak. October. Infrequent. No. 1742. This 

 is a very clean, neat form of the species. It has a uniform tawny-olive 

 color. 



103. Polyporus pubescens (Schumacher) Fries. 



On cherry, Corvallis. April. Frequent. No. 1834.
