eted or honeycomb heart rot. North Carolina and Ohio to 

 Mexico, and in Cuba. 



In general aspect S. subpileatum is not distinguishable from 

 S. sepium and S. insigne; it is more commonly met with than 

 these latter species and with them occurs on oak logs, is also 

 tobacco-colored and sulcate above and has a whitish hymenium 

 which differs from the other species of this group by containing 

 cylindric, incrusted cystidia and only very rarely an occasional 

 paraphysis with its outer portion of bottle-brush or aculeate 

 form. Usually such paraphyses are not found in preparations 

 of the hymenium of this species. Occasionally preparations 

 may show young cystidia which are merely rough above or some- 

 what aculeate. One must not confuse S. subpileatum with the 

 other species which have numerous and conspicuous bottle- 

 brush paraphyses.
