 136 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Resupinate portion 3X2 cm.; the free margin up to 5 mm. 

 broad. 



On under side of dead, fallen limbs of Liquidambar and mossy 

 dead trunk of Carpinus. North Carolina and Alabama. Jan- 

 uary. Rare. 



S. styracifluum is intermediate between S. rameale and S. 

 rugosum; in the region where it occurs it is likely to be regarded 

 as a resupinate form of S. rameale, from which it differs in darker 

 and more irregular hymenial surface, greater thickness of fructi- 

 fication, margin sometimes with a black edge, and reflexed part 

 tomentose to the margin; the pale-colored conducting organs 

 are similar in the two species but rather more abundant in S. 

 styracifluum. The general aspect is so similar to that of *S. 

 rugosum, very common in Europe, that the yellow milk of S. 

 styracifluum was properly regarded by Schweinitz as an impor- 

 tant distinctive character of the American species; other differ- 

 ences are that the intermediate layer is much broader and denser 

 than that of S. rugosum, that the hymenium is only 20-30 m 

 broad, never zonate, and that the conducting organs are much 

 less numerous and paler than in >S. rugosum.
