woods and mossy swamps. It is most often found under or near pine trees 

 and occurs from July to September. The tubes near the margin of the 

 cap do not separate easily from it and in preparing specimens for cook- 

 ing it is not necessary to discard them. 



Boletus Clintonianus Pk. 



Clinton's Boletus 



PLATE 6 1 Jig. 6-1 o 



Pileus convex, very viscid or glutinous, glabrous, golden yellow, red- 

 dish yellow or chestnut color, flesh pale yellow or whitish, tubes adnate, 

 their mouths small, angular or subrotund, pale yellow when young, ochra- 

 ceous when mature, changing to brown or purplish brown where bruised; 

 stem equal or slightly thickened at the base, annulate, solid, yellow above 

 the annulus, colored like the pileus below, the annulus thick, persistent, 

 white or whitish; spores brownish ochraceous, .0004 to .00045 in. long, 

 .00016 to .0002 broad, 



Clinton's Boletus is variable in color. In the typical form, which is 

 represented on plate 61, the color is reddish brown or chestnut, but speci- 

 mens occur in which it is reddish yellow or even golden yellow. The 

 surface of the cap is veiy viscid when moist, smooth and shining when 

 dry. The flesh is whitish or pale yellow, but it is apt to fade or become 

 dingy by exposure to the air. The taste is mild. 



The tubes are at first concealed by the thick veil. This soon separates 

 from the margin of the cap and forms a thick persistent collar on the 

 stem. When first exposed the tubes are pale yellow, but they become 

 ochraceous or dingy ochraceous in the mature plaiit. Their mouths are 

 small and nearly round. 



The stem is stout, solid and nearly equal in thickness in all its parts. 

 It may be straight or flexuous. It is yellow above the collar and colored 

 like the cap below it. Sometimes the extreme apex is shghtly re- 

 ticulated by the decurrent walls of the tubes, but it is not dotted. 

 The cap is 2 to 5 in. broad ; the stem 2 to 5 in. long, 4 to 9 lines 

 thick. This Boletus grows in woods and in open places and is generally 

 found under or near tamarack trees. It is specially fond of damp, 

 mossy places, and occurs from July to September. Because of their 

 viscidity the caps are often soiled by adhering dirt or fragments of 

 leaves. It is well therefore to peel them in preparing them for the table 

 and to remove the tubes. It is excellent in flavor and is a fine addition 

 to our hst of edible species.
