SPECIES OF VISCID B0LET1. 65 



Boletus granulatus L. 



Granulated Boletus. 



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

 when moist, variable in color, pinkish-gray, reddish-brown, yellowish, 

 tawny-ferruginous or brownish, flesh white or tinged with yellow ; 

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

 becoming dingy-ochraceous ; stem subequal, rather short, not annu- 

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

 pallid, sometimes yellowish ; spores ocltraceo ferruginous, subfusiform, 

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



Plant gregarious, pilous 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 live such 

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

 be regarded by some as mere varieties of a single extremely variable 

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

 be constant and decisive. 



B. granulatus 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. flavor uf 'us 

 Sclnefl'., B. lactifluus Sow. and B. circinansPers. are synonyms. 



Boletus ore vines Pk. 



Short-Stemmed Boletus. 



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

 or moist, dark-chestnut color, sometimes fading to dingy-tawny, the 

 margin in flexed, flesh white or tinged with yellow ; tubes short, nearly 

 plane, adnate, small, subrotund, at first whitish, then yellowish, 

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

 not dotted or rarely with a few very minute and inconspicuous 

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



Solitary or gregarious, pileus 1.5 to 2.5 in. broad, stem .5 to 1 in. 

 long, 3 to 5 lines thick. 



Sandy soil in pine woods. Albany county. October.
