may be determmed by its rings of growth. Perhaps the tyro may observe that in the list of synonymes 

 there appears Boletus suaveolens, Liunseus, as if in contradiction to the title Tolyjjorm suaveolem; now 

 this is not intended, but that the name of the class being modernly Folj/j^orus, Limiseus is still cited as the 

 authority for the species, although he called it a Boletus, in wliich he was imitated by Sowerby, Withering, 

 &c.. Ills more immediate followers ; but the term is now very properly restricted to a class, formed according 

 to strictly natural arrangement, which includes only the soft fleshed central stemmed varieties, with tubes 

 separable from the pileus, and each other; these, having in youth a rotund or baU-like appearance, may 

 fairly be named Boletus, but the title is quite inappropriate to the irregular, generally dimidiate class, 

 growing on trees &c., and which, having pores sunk into the pileus itself or formed fi'om the fibres of its 

 substance, instead of being separable from it, are considered as the true type of Folyporus. The great 

 family of the Bolypon then includes all pored Tunguses, of which Boletus is only one division, and Poli/porns 

 anotlier. In virtue of this arrangement it is clear that although every Boletus is a member of the Polyporei, 

 it by no means follows that a Polyporus is a Boletus. 



Nothing can be more objectionable than novel arrangements or changes of nomenclature without 

 sufficient cause ; but in this case every one who will take the trouble to consider the subject, must perceive 

 ■ that difl'erences enougli exist between the present family of Boletus, and those now termed Folyporus to 

 justify a separation. 



Folyporus suaveolens, when dried and powdered, has been employed, it is said successfully in consumptive 

 cases ; it appears at any rate to have effectually checked distressing night perspirations and other attendant 

 symptoms of that melancholy disease. It is of too tenacious a consistence to be used as food, and too scarce 

 to render that an important consideration.
