BOLETUS RUBINELLUS. 



BY H. C. BEARDSLEE. 



Through the courtesy of the British Museum officials, extended 

 through Mr. Lloyd, I have been able to compare the microscopic 

 structure of Boletus rubinellus with that of its close relative, the 

 Knglish Boletus rubinus. 



The American species seems to be rather rare. It occurs every 

 summer at Asheville, where I find it in pine woods in August. It is 

 one of our most interesting species, and is marked especially by its 

 small size (the pileus being 2-4 cm. broad), and the unusual color 

 of the tubes, which are a beautiful carmine in the young plant and 

 fade to ferruginous as the spores develop. A number of our species 

 have the mouths of the tubes more or less red, but the tubes are 

 yellow within. This is not the case in this species in which the tubes 

 are of one color, though this changes as has been indicated. One 

 who has watched it growing would hardly be willing to classify it 

 with Luridi, as classed by Mr. Murrill, along with B. Frostii and B. 

 luridus. Personally, I should prefer to place it in Subtomentosi, to 

 which Smith referred his species. The pileus is slightly viscid at 

 times, but it should scarcely be placed with Viscidi. 



The interesting question in regard to this species is its relation- 

 ship to Boletus rubinus. The English species has all the gross char- 

 acters of our plant. It has the same small size, same yellow, un- 



NOTE. We take the liberty of publishing two Porias, received from Rev. H. Bourdot, with his 

 figures and description. We do not know that Rev. Bourdot expects us to publish them, but as the 

 specimens are in our museum, we think it well to legalize the names.
