Murrill: Pacific Coast Polyporaceae and Boletaceae 99 



species to preserve, owing to its extremely juicy consistency. It 

 differs from nearly all other boleti in its floccose covering, which 

 resembles that found on the surface of Boletellus Ananas and 

 Strobilomyces strohilaceus, but the scales are more rigid and 

 conic in shape. The collector may readily distinguish it from 

 these two species by its bay color and the absence of a veil. Both 

 of the other species mentioned possess a conspicuous veil, and 

 the former is tan to brown with a pinkish tint, while the latter is 

 dark-brown or black. Mr. Zeller has photographed this species 

 for me, and Mrs. Murrill made a very accurate colored sketch 

 of it.

Ceriomyces oregonensis sp. nov. 



Pileus convex, firm, solitary, 12 cm. broad; surface bay, even, 

 not viscid, short-tomentose to subglabrous, 12 cm. broad, margin 

 entire or slightly lobed, scarcely projecting: context firm, white, 

 unchanging, mild, odor not characteristic; tubes very large, 2-3 

 mm. in diameter, depressed and radially elongate about the stem, 

 ventricose, flavous to dull greenish-yellow, melleous within, not 

 changing when bruised; spores oblong-ellipsoid, smooth, mel- 

 leous, 10-12X4/^; stipe larger below, solid, white within,

 at the center. 



This species was collected on the ground in sandy pine barrens 

 on the immediate coast at Newport, Oregon. Although grow- 

 ing in sand, the weather conditions were very humid.
