Boletus subluteus 2. 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, s/ender, annulate, pallid or yellowish, marked both above 
and below the annulus with reddish or brownish glandular dots, annu- 
lus submembranous, g/udénous, at first concealing the tubes, then co/- 
lapsing and forming a narrow whitish or brownish band about the 
stem ; spores ochraceo-ferruginous, subfusiform, .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. duteus, 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 asa 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 72. sp. 
American Boletus. 
Pileus thin, convex or nearly plane, soft, very viscid or glutinous 
when moist, slightly domentose 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
