resemblance of this species to Boletus angustalus, Sow., t. 193, 

 -whose figure would be an excellent representation of it in every 

 respect if the pores were smaller. Fries'a character of Dceda- 

 lea any nut at a conveys an entirely wrong notion of the species, 

 which is one of the most beautiful of European Fungi. The 

 colour is not, as characterized by Fries, who had only seen the 

 figure, " fusccscenti-cinereus," but as figured and described by 

 Sowerby, " dull crimson, somewhat satiny on the edges, which 

 are of a silvery brown."
