Pileus ascending, depressed behind, reniform, irregular, fleshy- 

 tough, solitary, 15 cm. wide, 25 cm. long, 3 cm. thick behind; 

 surface dry, dark-fulvous, uniformly and densely imbricate- 

 floccose-scaly, the ends of the scales either slightly upturned or 

 at an angle of 45°, margin concolorous, fertile, lobed or undulate, 

 bay when bruised ; context white, nutty, thin, fragile when fresh, 

 with the odor of musty meal when dry ; tubes white, tinged with 

 sulfur-yellow when bruised, decurrent, mouths regular, thin- 

 walled, I mm. in diameter, edges uneven, toothed; spores ovoid, 

 smooth, hyaline, 8-10 X 5/^; stipe eccentric, inflated, 7 cm. long, 

 8 cm. thick, irregular, watery-white to flavous, turning sulfur-

 attachment and not reticulate behind. 



This large and handsome species was collected November 9, 

 1911, on a rocky bank among giant red firs to the north of Mill 

 City, Oregon, at an elevation of 1,200 ft. Its nearest relative is
