Boletus nobilis Pk. n. sp. 

 NOBLE BOLETUS 



PLATE 91, FIG. 1-4 



Pileus firm, convex, dry, glabrous, yellowish brown or reddish 

 brown when young, becoming ochraceous or reddish ochraceous 

 with age, flesh white, taste mild; tubes white and stuffed when 

 young, becoming yellow or pale ochraceous with age, nearly plane 

 in the mass, adnate or slightly depressed around the stem, the 

 mouths small, round; stem equal or slightly thicker at the base, 

 solid, glabrous, generally reticulated at the top, whitish or pallid; 

 spores oblong fusiform, .0005-. 0006 of an inch long, .0002-. 00024 

 broad. 



This large and fine species grows singly or in groups in thin 

 woods and in cleared or bushy places. It belongs to the section 

 Edules. It differs from the edible boletus, B . edulis in its 

 tubes being less depressed around the stem and in having no 

 green tint. From the related boletus, B. affinis, to which 

 it is also closely allied, it is separated by its larger size, the paler 

 color of the cap, the paler stem and its larger spores. The flesh 

 is thin for the size of the cap and is yellowish next the tubes. 

 The cap is 4-8 inches broad; the stem 3-6 inches long, 6-10 lines 

 thick. It may be found in August. In preparing it for cooking 

 the long tubes should be removed from the cap and be rejected 

 with the stem. 



Strobiiomyces strobilaceus (Scop.) Berk. 



CONELIKE BOLETUS 



PLATE 92, FIG.- 1-6 



Pileus fleshy, firm, subglobose, hemispheric or convex, dry, 

 covered with a dense thick coat of blackish or blackish brown 

 tom.entum which separates into prominent tufts or scales with 

 intervening chinks or spaces of a pale gray or smoky white color, 

 flesh whitish, changing to reddish on exposure to the air, then to 

 blackish, tubes rather long, depressed around the stem, plane or 

 convex in the mass, whitish when young and fresh, becoming red 

 where wounded and then blackish, also becoming blackish or 

 blackish brown with age; stem equal or tapering upward,, solid, 

 often sulcate at the top, covered with a toment^im similar to that 

 of the pileus; spores blackish brown, globose or nearly so, rough, 

 .0004-. 0005 of an inch in diameter. 



This boletus has such a peculiar shaggy appearance and black- 

 ish color and is so unlike any other mushroom in our flora that
