SPECIES OF VISCID BOLETI. gl 



aiiijiilur or subrotiind, pule-vellow when vouiifr, becomiucr diiifry- 

 ochraceou.s, changing to purplish-brown where bruised ; stem equal 

 or slightly thickened at the base, straight or flexuous, annulate, 

 yellow at the aj)ex. elsewhere reddish or reddish-brown, sometimes 

 stained with yellow, slightly reticulate at the apex by the decurrent 

 walls of the tubes, annul us ivJiitisJt or yellow, persistent, forming a 

 thick tonientose band about the stem ; spores brownish- ochraceous, 

 .0004 to .000-45 in. long, .00016 to .0002 broad.' 



Plant single or rarely caespitose, pileus 2 to 5 in. l)road, stem 2 to 

 5 in. long, 4 to 9 lines thick. 



Mossy ground in woods and grassy ground in open places ; gener- 

 ally under or near larch trees. 



This fine species is apparently the American analogue of the Euro- 

 pean B. elegans, from which it diffei-s in its generally darker color, 

 in its persistent, not fugacious, aunulus, and in its stem, which is not 

 at all dotted, either aliove or below the annulus. It is edible, and 

 has a mild taste in the fresh uncooked state. It has occurred once 

 in "Washington Park, Albany, near some larch trees, with which it was 

 prol)ably introduced. 



Boletus luteus L. 

 Yellow- brown Boletus. 



Pileus gibbous or convex, sometimes nearly plane, viscid or glutin- 

 ous when moist, virgate-spotted, yellosvish-brown, flesh white or yel- 

 lowish ; tubes small, simple, adnate. at first pale-yellow, then dingy- 

 ochraceous ; stem stout, rather short, annulate, rough u-i(h dots and 

 yellowish above the ring, browni.sh-white or yellowish below, the annu- 

 lus large, membranous, whitish or brownish-white ; spores ochraceo- 

 ferruginous, nearly fusiform, .0003 in. long, .00015 broad. 



Gregarious or rarely subcaespitose, pileus 2 to 5 in. broad, stem 

 1 to 2 in. long, 5 to 8 lines thick. 



Under pine trees, Pinus sylvestris. Menands. October. 



This is the only instance in which I have observed this species in our 

 State. Possibly it may have ))een introduced in this place with the 

 young pines under which it was growing. Its annulus is very conspicu- 

 ous. It is sometimes torn and partly adherent in fragments to the mar- 

 gin of the pileiis. In short-stonnned s[)ocimens it extends downwards 

 and covers the lower part of the stem like a sheath, resembling in this 

 respect the western Boletus sj)ha'roy)orus, a related species. In other 

 specimens it forms a broad band with theuppei margin widely spread- 

 ing. In the dried specimens the pileus has assumed a dull-l)rownish 

 or reddish-brown hue. The plant is edible.
