Boletus subluteus n. sp. 



Small Yellowish Boletus. 



Pileus convex or nearly plane, viscid or glutinous when moist, 

 sometimes obscurely virgate-spotted, dingy-yellowish inclining to fer- 

 ruginous-brown, flesh whitish varying to dull-yellowish ; tubes plane 

 or convex, adnate, small, subrotund, yellow, becoming ochraceous ; 

 stem equal, slender, annulate, pallid or yellowish, marked both above 

 and below the annulus with reddish or brownish glandular dots, annu- 

 lus submembranous, glutinous, at first concealing the tubes, then col- 

 lapsing and forming a narrow whitish or brownish band about the 

 stem ; spores ochraceo-ferruginous, subfiisiform, .0003 to .0004 in. 

 long, .00016 to .0002 broad. 



Solitary or gregarious, pileus 1.5 to 3 in. broad, stem 1.5 to 2.5 in. 

 long, 2 to 4 lines thick. 



Sandy soil in pine woods or groves. Albany and Lewis counties. 

 September and October. 



In the Twenty-third Report this fungus was referred as an aber- 

 rant form to B. luteus, which it much resembles in its general char- 

 acters. But I find it so constant in its peculiar features that I am 

 disposed to regard it as a distinct species. It differs from B. luteus 

 in its smaller size, more slender stem and glutinous collapsing annu- 

 lus. This never extends downwards so as to sheathe the lower part of 

 the stem, but forms a narrow band with scarcely any spreading 

 margin. Besides the stem is conspicuously dotted both above and 

 below the annulus. The markings of the pileus in this species, B. 

 luteus and B. Elbensis are similar and resemble little patches of innate 

 brownish fibrils. The species is probably edible, but I have not 

 tested it. 



Boletus Americanus n. sp. 



American Boletus. 



Pileus thin, convex or nearly plane, soft, very viscid or glutinous 

 when moist, slightly tomentose on the margin when young, soon 

 glabrous or slightly squamose on the margin, rarely wholly squamose- 

 spotted from the drying of the gluten, pale-yellow, becoming dingy 

 or less bright with age, sometimes vaguely dotted or streaked with 

 bright-red, flesh pale-yellow, less clear or pinkish-gray on exposure 

 to the air ; tubes plane or convex, adnate, rather large, angular, 

 pale-yellow, becoming sordid-ochraceous ; stem slender, equal or 

 slightly tapering upwards, firm, not at all annulate, yellow, sometimes 

 pallid or brownish toward the base, marked with numerous brown or
