OLIVE-RED BOLETUS 
Bull. Buff. Soc. 1874, p. ror 
Pileus at first convex and firm, then nearly plane, soft and 
spongy, glabrous, vermilion, becoming olivaceous, flesh pale- 
yellow, changing to blue where wounded; tubes bright lemon- 
yellow, adnate or subdecurrent; stem glabrous, enlarged at 
the top, pale-yellow, brighter within, sometimes lurid at the 
base; spores .o005 in. long, .00025 broad. 
Var. senszbeles. (Boletus senszbtls Rep. 32, p. 33-) 
Pileus at first pruinose-tomentose, red, becoming glabrous 
and ochraceous-red with age; tubes bright-yellow tinged 
with green, becoming sordid-yellow; stem lemon-yellow with 
red or rhubarb stains at the base, contracted at the top 
when young, subcespitose; spores .0004 to .0005 in. long, 
.00016 to .o002 broad. 
Pileus 2 to 6 in. broad; stem 3 to 4 in. long, 3 to 6 lines 
thick. 
Woods and their borders. New England, frost. New 
York, Peck. 
Though the sensitive Boletus differs considerably in some 
respects from the olive-red Boletus it is probably only a 
variety and as such I have subjoined it here. In it, every 
part of the plant quickly changes to blue where wounded, 
and even the pressure of the fingers in handling the fresh 
specimens is sufficient to induce this change of color. The 
character suggested the name given to the variety. I have 
not found the typical plant in New York, but specimens 
received from Mr. Frost are not, in the dry state, distinguish- 
able from the variety. oletus subtomentosus, Palmer's 
Mushrooms of America, Plate VII, fig. 4, appears to belong 
to this species.
