Fructifications of this species have the general aspect of those 

 of S. papyrinum, but are thinner, more compactly inter- 

 woven, with slenderer cystidia, and have the hymenial layer up

 present in each of these zones, and those of the innermost zones 

 do not reach to the surface of the hymenium. In S. papyrinum
