 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 n 

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

 less numerous and paler than in S. rugosum.
