Boletus ixflexus. Pileus convex, glabrous, viscid, yellow, 

 often red or reddish on the disk, the margin thin, inflexed, con- 

 cealing the marginal tubes, flesh whitish, not changing color 

 where wounded; tubes rather long, adnate, yellowish, becoming 

 dingy-yellow with age, the mouths small, dotted with reddish 

 glandules ; stem rather slender, exannulate, solid, viscid, dotted 

 with livid-yellow glandules; spores yellowish, .0004 to .0005 in. 

 long, .00016 to .0002 broad. 



Pileus about I in. broad; stem about 2 in. long, 2 to 4 lines 

 thick.

This Boletus belongs to the tribe Viscipelles. It is remarkable 

 for and easily recognized by the inflexed margin of the pileus, 

 which imitates to some extent the appendiculate veil of Boletus 

 versipellis. It sometimes grows in tufts. The paper in which 

 fresh specimens were wrapped was stained yellow. Boletus 

 Braunii Bres. has an inflexed margin, but that is a much larger 

 plant with a yellowish-brown pileus, a fibrillose stem and much 

 smaller spores. 



Polyporus axceps. Effuso-reflexed or resupinate, inseparable 

 from the matrix, firm, subcorky but flexible, white ; pileus narrow, 

 about 6 lines broad, laterally elongated or confluent, minutely 

 downy, sometimes rugosely pitted; pores minute, subrotund, 

 commonly 2 to 3 lines long, the dissepiments obtuse; mycelium 

 white, permeating the bark and wood.

The plants are commonly resupinate, but sometimes reflexed, 

 forming a narrow pileus about half an inch broad but extending 

 laterally for several inches. They are suggestive of the first year's 

 growth of P. connatus Fr., but they do not revive the next year, 

 and they have a different habitat. Though differing somewhat in 

 texture they are apparently related to such species as P. scmisupi- 

 nus and P. semipileatus, and with them they serve to connect the 

 genus Polyporus with the genus Poria. 



Sparassis Herbstii. — Plants much branched, forming tufts 4 to 

 5 in. high and 5 to 6 in. broad, whitish, inclining to creamy-yel- 

 low, tough, moist, the branches numerous, thin, flattened, con- 

 crescent, dilated above and spatulate or fan-shaped, often some- 

 what longitudinally curved or wavy, mostly uniformly colored, 

 rarely with a few indistinct, nearly concolorous, transverse zones
