Peck : New Species of Fungi 17 



breaking into fragments and disappearing: spores elliptic, 6-7.5 

 [i long, 4-5 /jt broad. 



Pileus 2.5-5 cm - broad : stem 5-14 cm. long, 4-6 mm. broad. 

 Cespitose. Mountain pastures. Linden, Va. August Mrs. 



E. M. Williams. 



Boletus caespitosus 



Pileus broadly convex or nearly plane, sometimes slightly con- 

 cave by the elevation of the margin, even, brown or blackish brown, 

 the margin often a little paler or reddish brown, flesh slightly tinged 

 with red : tubes adnate or slightly decurrent, yellow, their mouths 

 rather large, angular, concolorous : stem short, even, solid, gla- 

 brous, tapering upward, brown or reddish brown : spores oblong 

 elliptic, 10 /Jt long, 5 /abroad. 



Pileus 1-2.5 cm - broad : stem 2-2.5 cm. long, 4-6 mm. thick. 



Cespitose. Virginia. August. R. S. Phifer. 



A small species growing in tufts and referrable to the tribe 

 Subtomeutosi. The tubes retain their bright yellow color in the 

 dried specimens. • 



Boletus subsanguineus 



Pileus convex or slightly depressed in the center, glabrous, 

 viscid, bright red or scarlet, flesh thick, firm but flexible, white, 

 slowly changing to a pale brownish lilac on exposure to the air, 

 taste slightly bitter : tubes very short, 2-4 mm. long, adnate but 

 often separating from the stem with the expansion of the pileus, 

 reddish, the mouths minute, stuffed at first, pinkish, then brown- 

 ish yellow changing to a light brown where wounded : stem short, 

 thick, uneven, often tapering downward, streaked with red, pale 

 yellow at the top, white at the base, marked at the top by the de- 

 current walls of the tubes. 



Pileus 2.5-10 cm. broad : stem 2.5-5 cm. long, 2-4 cm. thick. 



Solitary, gregarious or cespitose. Under beech trees. West 

 Philadelphia, Pa. August. C. Mcllvaine. 



This is a very showy species, easily recognized by its bright red 

 viscid pileus and its short thick and uneven or somewhat lacunose 

 stem. It is closely related to the European B. sanguineus With 

 from which it is separated by its minute tubes, its uneven stem and 

 the brownish hues assumed where wounded. 



The spore characters of this and the four succeeding species are 

 unknown, but the other characters are quite distinctive and ap-
