free, ventricose, brownish pink, becoming blackish brown or black; stem 

 equal or slightly tapering upward, stuffed or hollow, glabrous, whitish or 

 pallid, the annulus thin, persistent, white ; spores elliptic, brown, .0002 of 

 an inch long, .00015-.00016 broad. 



The diminutive mushroom is a small but symmetric and beauti- 

 ful species. Its cap is thin and fragile and broadly convex or nearly 

 flat when mature. Its center is usually brown or reddish brown, 

 and there are also small spots or thin, spot-like scales of similar 

 color on the cap. These are often rather obscure and rarely are 

 seen on the margin. Toward the margin the cap is usually whitish, 

 but sometimes it is tinted with pink or reddish brown. The young 

 gills are pink but less bright than in the common mushroom, and 

 they soon assume the blackish brown color of maturity. The stem is 

 slender, straight, stuffed with a white pith when young but generally hol- 

 low when mature. It is whitish or somewhat darker when old and 

 adorned with a white, thin, membranaceous, persistent collar, which is 

 sHghtly downy on its lower surface. 



The cap is 1-2 inches broad; the stem 1.5-2 inches long and 1-2 lines 

 thick. The plants grow among fallen leaves or on mossy ground in 

 woods. They occur in August and September. They are not often 

 abundant, and this with their small size detracts from their importance 

 as an edible species. Fried in butter, they are very palatable.

WHITE FLESH BOLETUS 

 PLATE 76, FIG. 21-25 



Pileus fleshy, convex above, dry, subglabrous, varying from brick red 

 to bay red, flesh white, sometimes tinged with red near the surface ; 

 tubes rather long, adnate or slightly depressed around the stem, green- 

 ish yellow, their mouths small, subrotund; stem equal or nearly so, sohd, 

 subglabrous, colored Hke or a little paler than the pileus, white within. 



The white flesh boletus is quite common in the Adirondack forests and 

 quite constant in its characters. I have not seen it with yellow flesh 

 though in other respects it agrees very well with the description of B. 

 chrysenteron. The cap is not often cracked, but, when it is, the 

 cracks are sometimes red, sometimes yellowish, though the flesh is con- 

 stantly white except just beneath the cuticle, where it is sometimes red- 

 dish. The tubes are long and greenish yellow. They are at first nearly
