The genus Stro-bi-lom'-y-ces. — In the family Po-ly-po-ra'-cc-ac to 

 which this belongs, pores instead of gills from the lower side of the cap 

 and constitute the hy-we -ni-um. or spore-bearing layer. The common 

 genera are: (1) Fis-tn-li-na, which has the pores close together but free 

 from each other — all the others have the pores joined side by side; (2) 

 Po-ly -/yo-rus, firm, often corky or woody; (3) tner-ii -li-iis, with tubes or 

 pores shallow, formed by a network of folds or wrinkles, plants somewhat 

 gelatinous; (4) Bo-le -tits, not woody or corky, the mass of tubes easily 

 separable from the cap when pulled off; (5) Stro-bi-lom -y-ces. the 

 stratum of tubes not so easily separating, and cap with coarse prominent 

 scales. Both the generic and specific name of the common species refer 

 to Its slight resemblance to a pine-cone. This character readily separates 

 it from a Boletus. The flesh is whitish, but changes to reddish and later 

 to black when wounded or cut.
