 white, tasteless; lamellae adnate, becoming sinuate-adnexed or 

 nearly free, ventricose, plane, close, white, changing to rust-

 stipe equal or tapering downward, dry, smooth below, somewhat 

 scaly above the annulus, white tinged with cremeous, 12 cm. long, 

 3 cm. thick; annulus ample, persistent, membranous, white, at-

Type collected in the sand hills among scrubby pines on the 

 immediate coast at Newport, Oregon, November 13, 191 1, W. A. 

 ■Murrill 1044. A species remarkable for its size and habit of 

 living in apparently pure sand, although the source of its food 

 is doubtless buried humus. In general appearance, it resembles 

 Armillaria magnivelaris Peck.
