pofTefs it than the former, devouring the larger pro- 

 portion of the infide fo completely as to leave only 

 the pileus and pores to the viciffitudes of the weather. 

 The chara6ler of " fuperne Isevis" (Linn.) does not 

 quite agree with either of thefe plants. This is always 

 more or lefs downy, though the B. falicinus in the 

 latter ftate is often nearly fmooth. This and the two 

 preceding exhale a fragrant fcent till they become 

 quite dry.

BOLETUS VERSICOLOR. Linn. 



VVh ETHER this plant found on the oak, or thofe 

 fo frequent on the willows, be what Linn?eus intended, 

 has created fome doubts. I think this is exa(5lly his 

 B. verjicolor., and it may very well include the thinner 

 varieties that grow on the willow. The pileus in the 

 former is of a tawny colour, in the latter grey or 

 blueifli. I have a Boletus altogether of a tawny hue, 

 which feems lefs acceptable to infedts, and which I be- 

 lieve is a variety. The two firft are conftantly eaten 

 by infects. They prefer the thickeft, not defpiling 

 any that has the leaft fubftance between the pileus and 

 pores. All thefe varieties are covered with different 

 degrees of pubefcence, either plufli-like or fatiny, in 

 concentric zones ; the variety of whofe colours adds 

 much to the effe6t of light and fliadow caufed by 

 their relief.

 BOLETUS PELLOPORUs. Bull. 501,7^-. 2. 



This and the following plant feem very nearly re- 

 lated. The figures of Bulliard, with my fpecimens, 

 make me think them fpecies. In the more perfe(51: 

 Itate than figured by Bulliard they are without black 

 pores, which feem the effedt of decay.
