10. Pleurotus (Fries) Quel. Champ. Jura Vosg. 77. 1872 

 Pleurotus dryinus (Pers.) Quel. Champ. Jura Vosg. 77. 1872 



This species is provided with a conspicuous veil and the surface 

 is usually more or less areolate in appearance owing to the break- 

 ing up of the cuticle. Pleurotus corticatus (Fries) Quel, and 

 Pleurotus subareolatus Peck are apparently not distinct. Found 

 in Washington on decayed spots in living trunks of alder and 

 large-leaved maple, sometimes reaching 13 cm. in breadth. 



Seattle, Washington, Murrill ^86, 620.
