plane surface below, but sometimes this is distinctly concave 

 in the young plant and convex in the mature one. They are 

 often slightly depressed around the stem and then their mouths 

 in the depressed part are usually a little larger than elsewhere. 

 Their color is a very pale yellow or greenish yellow and they 

 change to bluish where wounded or bruised. The stem is gener- 

 ally rather long and flexuous though sometimes it is short and 

 straight. It is solid, smooth and whitish, but sometimes 

 streaked with brown and tinged with red within. 



The cap is 2-4 inches broad; the stem 2-5 inches long and 

 3-8 lines thick. The plants inhabit thin woods, groves and 

 open places, and may be found from July to September. This 

 is an excellent boletus for the table, is easily recognized and 

 generally free from the attacks of insect larvae. This and the 

 preceding species, together with the red cracked boletus,. 

 B. ohrysenteron, show how unreliable is the rule that 

 directs the avoidance of all boleti whose flesh or tubes change 

 to blue where wounded.

ORNATE STEMMED BOLETUS 

 PLATE 80, FIG. 1-5 



Pileus fleshy, firm, hemispheric becoming convex or nearly 

 plane, minutely tomentose or glabrous, gray, grayish brown 

 or yellowish brown, flesh yellow; tubes nearly plane in the 

 mass when young, convex when old, adnate or slightly de- 

 pressed around the stem, golden yellow, their mouths small, 

 subrotund; stem equal or nearly so, solid, firm, distinctly and 

 beautifully reticulated, yellow without and within; spores 

 ochraceous brown, oblong or subfusiform, .00045-00055 of an 

 inch long; .00016-.0002 broad. 



The attractive characters of the ornate stemmed boletus and 

 those by which it may readily be recognized are the beautifully 

 reticulated yellow stem, yellow tubes and clean dry grayish or 

 brownish cap. The cap is hemispheric in the young plant, 

 broadly convex or nearly plane in the mature one. It is dry
