Zeller: Contributions to Oregon Fungi 



185 



On very rotten, decorticated, frondose wood, Corvallis, Oregon, Sep- 

 tember 28, coll. S\ M. Zeller 1772, type (in Mo. Bot. Gard. Herb. 56849). 



M. pilosus is distinguished by its capucine-buff color, fleshy structure, 

 presence of gloeocystidia and cystidia, and the minute spores ; gloeocys- 

 tidia have not been found in any other North American species with the 

 exception of M. rugulosus of the West Indies. 



All of the above notes and diagnosis of M. pilosus was kindly sent 

 to the writer by Dr. E. A. Burt. The accompanying photograph (Fig. 

 1) of the type was taken when the collection was made. 



116. Merulius tremulosus Schrader. 



Although Dr. Burt did not examine any specimens of this species 

 from Oregon, it is very common on decaying, hard woods during the 

 fall months. 



6. Family Agaricaceae 



117. Amanita muscaria Fries. 



In the sandy tide flats along Willamette River, Corvallis. September. 

 Frequent. No. 2153. 



This poisonous Amanita is very common in the early fall on the 

 sandy bottom land along the Willamette river. The plants are very large 

 and striking in color, the disk usually English red and the margin 

 orange-chrome. A specimen reaching 28 cm. high and with a pileus 21 

 cm. broad weighed 3 lbs., 6 ozs. 



118. Amanita calyptrata Peck. 



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

 Nos. 1766, 2126. 



119. Amanita pantherinoides Murrill. 



In coniferous woods and open oak thickets, Corvallis. November. 

 Frequent. No. 2150. 



120. Amanita solitaria Fries. 



Solitary on ground in oak woods, Corvallis. October and November. 

 Rare. No. 2063. 



This plant has not previously been reported from Oregon although it 

 is known to grow on the Pacific slope in California. According to Dr. 

 Gilkey it has been collected in past years in several counties in this 

 vicinity. Our plants have practically no odor nor taste unless slightly 

 farinaceous. 



121. Amanita chlorinosma Peck. 



Solitary on ground in scrubby oak thicket, Corvallis. October and 

 November. Rare. Collected by Mr. Carl C. Epling (333). 



This species is strikingly like A. solitaria in morphological characters 

 differing, however, in size of spores and in odor. A. chlorinosma has 

 a strong, marked odor. In the specimen cited above the odor was desig- 

 nated as " of potash or of strong alkaline urine." 



122. Amanitopsis vaginata Fries. 



In coniferous woods mostly, Mary's Peak. October. Common. No. 

 1778.
