are sometimes marked by transverse white stripes. The species 

 belongs to the section Gennina and is respectfully dedicated to its 

 discoverer who kindly communicated notes and specimens. 



Omphalia subclavata 



Pileus thin, submembranaceous, subclavate or tubaeform, 

 deeply umbilicate, glabrous, grayish brown ; lamellae subdistant, 

 very decurrent, yellow ; stem slender, subpruinose, often tomen- 

 tose near the base, hollow, whitish ; spores elliptic, 6—7*5 /^ l° n £> 

 4-5 fx broad. 



Pileus 6-12 mm. broad ; stem about 2.5 cm. long, 1 mm. thick. 



Dead bark. Missouri. July and August. N. M. Glatfelter. 



This species differs from O. clavata in its yellow lamellae and 

 elliptic spores and from 0. tnbaeformis in its yellow lamellae, 

 whitish stem and longer spores. 



Boletus roseotinctus 



Pileus broadly convex or nearly plane, firm, dry, pruinose, 

 pink or pale rosy red, flesh yellowish white ; tubes short, adnate, 

 yellowish, their mouths minute, subrotund, the dissepiments un- 

 even on the edge ; stem equal, even, yellow above, red or purplish 

 red below; spores oblong, 10-12/i long, 4-5 //broad. 



Pileus about 5 cm. broad; stem 3-5 cm. long, 8-12 mm. 

 thick.

Blue Ridge. July and August. G. F. Atkinson. 



The pileus is firm in the mass but its flesh is soft to the touch 

 and almost friable. It is separable into two strata, the lower being 

 thinner than the other. It belongs to the section Subpruinosi. 



Boletus amabilis 



Pileus fleshy, convex, glabrous, reddish tawny, flesh pallid; 

 tubes short, decurrent to the annulus, yellow, their mouths angu- 

 lar ; stem equal or slightly tapering downward, solid, paler than 

 the pileus, reticulate above the slight annulus. 



Pileus 5-18 cm. broad ; stem 2.5-5 cm - !ong, 8-16 mm. thick. 



Dense spruce woods. Colorado. September. E. Bartholo- 



mew. 



In the dried specimens the pileus is marked with small brown 

 or blackish brown spots. The tubes have a radiating structure as 

 in the genus Bolctinus, to which genus the species may possibly be- 

 long, but it is not safe to affirm such relationship from the drie
