• 



Boletus Ravenelii B. & C.

 even the colors are well preserved. Above « B. subchromeus 

 Frost " is written " B. Ravenelii B. & C. first by publication."

statement that " B. retipes is not a good Vermont species." See 

 remarks under B. edulis. 



Boletus robustus Frost. 



Represented by three good plants collected in 1862 in the 

 borders of shady woods. A full description accompanies the speci- 

 mens. On account of Boletus robustus Fries, described earlier from 

 Costa Rica, Peck assigned a new name, B. eximius, to this species. 



Boletus Roxanae Frost. 



Four fair specimens with full description and an outline sketc 

 appear on one sheet. Another sheet has four good s P ecim ^ 

 and still another contains five in fair condition, at least one of w ic^ 

 is B. castaneus. This same sheet contains also a good s P ec ' m ^ 

 of the yellow-stemmed variety of B. Roxanae, first reported by ec

Peck is probably not distinct from B. Roxanae. (Plate 39.) 



Boletus rubeus Frost. 



Frost found this species in deep woods. There are 

 sheets, containing eight good plants and four rather P^ *, ^ 

 A study of these various specimens in connection with e 

 scription shows the species to be too near B. bicolor to be rega 

 as distinct. 



Boletus Russellii Frost. j ar cr e 



This handsome species is represented by three exce : en ^ 

 plants and five specimens only fairly well preserved, 

 collected in moist woods in 1862. (Plate 40.) 



Boletus salmonicolor Frost. horders 



Represented by twelve poor specimens collected in e ^ 

 of pine woods. This species is apparently synonymous 



luteus.
