Mycologia 



133. Pleurotus sapidus Schulzer. 



On maple, Corvallis. November. Rare. No. 2147. 



The spores in ours are 8-1 1 x 3-4 fi, becoming a very distinct pale 

 lilac in mass. The pileus is tan to ochraceous-yellow or gray. In North 

 American Flora, the range of distribution is given as far west as the 

 Rocky Mountains. 



134. Pleurotus serotinus Fries. 



On apple wood, Corvallis. December. No. 2069. This species has 

 been observed on various hard woods very late in the fall, but it seems 

 to be very frequent on winter-injured apple wood. 

 J 35- Hygrophorus eburneus Fries. 



In oak thickets and woods, Corvallis. September to November. No. 

 2044. This is one of our most common early mushrooms. 



136. Hygrophorus miniatus Fries. 



In dense Douglas fir woods, on moss, about four miles west of Alsea. 

 August. Observed but once and under conditions such that no collec- 

 tions were made. The plants were a deep vermillion with a white foot 

 of the stem as in var. sphagnophilus Pk. but were growing in heavy 

 mats of Hylocomium triquetrum instead of a Sphagnum bog. 



137. Lactarius pyrogalus Fries. 



In coniferous woods, Powers. October. No. 2041, collected by F. E. 

 Price. One lone specimen of this poisonous species was sent in for 

 identification. It is quite typical of those reported farther east. 



138. Russula ochrophylla Peck. 



One plant of this species was collected near Corvallis and brought iti 

 to our Mushroom Show in November. It was exceptionally large, meas- 

 uring 14 cm., but agreeing in all other characters with the usual descrip- 

 tions. Several specimens were observed in an oak grove at McMinnville 

 in December. 



139. Cantherellus aurantiacus Fries. 



A typical specimen of this species was sent in from Elgin. 



140. Cantherellus floccosus Schw. 



In damp, thick coniferous woods, Corvallis and Mary's Peak. October 

 to November. Not infrequent. 



141. Cantherellus infundibuliformis Fries. 



On damp soil in coniferous woods. Philomath. November. No. 2156. 

 Although this fungus has never been reported from the Pacific states it 

 is not a rare plant in western Oregon and Washington. 



142. Marasmius plicatulus Peck. 



Under pine on Oregon Agricultural College campus. December. No. 

 2173. This is a beautiful velvety species. 



143. Trogia crispa Fries. 



On prune bark, Corvallis. March. No. 2088. This is the first report 

 of this species west of the Rockies. Collection was made by C. E. Owens. 



144. Lenzites saepiaria Fries. 



This species is mentioned here because of its occurrence as a wound 

 parasite on peach and prune. It becomes quite a serious pest on peach 

 " trees when the orchards are adjoining coniferous woods. Nos. 1779, 1784, 

 1785, i93i.
