SPECIES OF VISCID BOLETI. ()5 



Boletus graiiulatiis L. 



Granulated Boletus. 



Pileiis thick, convex or nearly plane, very viscid or glutinous 

 when moirit, variable in co\o\\ pinkisJi-gray, reddish-hvovm, yellowish, 

 taivny-feri'uginous or broivnisJi, Hesh white or tinged with yellow ; 

 tubes nearly plane, adnate, small, at first whitish or very pale-yellow, 

 I)econiing dingy-ochraceous ; stem subequal, rather short, not ainni- 

 late, both it and the tubes marked with glandular dots, whitish or 

 pallid, sometimes yellowish ; spores oohraceo-fei'ruginous, subfusitbrm, 

 .0003 to .00035 in. long, .00016 broad. 



Plant gregarious, pileus 1.5 to 3 in. broad, stem 1 to 2 in. long, 

 4 to 6 lines thick. 



Woods, especially of pine, and in open places. Very common. 

 July to October. 



The pileus in this species is very variable in color, but it is never 

 wholly white as in the preceding species. Its stem is often dotted to 

 the base, but the dots or granules are generally more numerous and 

 distinct on the upper part. This and B. Boudieri appear to be the 

 only European species with exannulate glandular-dotted stems. If 

 we have correctly valued our forms, New York alone has five such 

 species. It is true, thej^ are closely related to each other, and might 

 be regarded by some as mere varieties of a single extremely varial)le 

 species, but to me the distinguishing characters here given appear to 

 be constant and decisive. 



B. gramdatus is recorded as edible by most authors. I have not 

 tested it. Gillet remarks that it ought to be regarded at least with 

 suspicion. B. collinitus in the Twenty -third Report, B. Jiavorufus 

 Schtett'., B. lad (fill us Sow. and B. circimms fevs. are synonyms. 



Boletus brevipes Pk. 



Short-yteniinetl Boletus. 

 Pileus thick, convex, covered with a thick, tough gluten when young 

 or moist, dai'k-cJtestnut color, sometimes fading to dingy -tawny, the 

 margin inflexed, fiesh white or tinged with yellow ; tubes short, nearly 

 plane, adnate, small, sul)rotund, at first whitish, then yellowish, 

 becoming dingy-ochraceous ; stem very short, not annulate, whitish, 

 not dotted or rarely ivith a few very minute a)id inconspicuous 



I dots at the ajjex ; spores subfusiform, .0003 in. long, .00012 broad. 

 \ Solitary or gregarious, pileus 1.5 to 2.5 in. broad, stem .5 to I in. 

 long, 3 to 5 lines thick. 

 Sandy soil in piuc woods. All)any (M)unty. October.
