Tli is species approaches Leptonia serrulata Fr. which also has 

 black-edged gills. At times this character is almost or entirely 

 absent except in old plants. Our plants had truly decurrent gills, 

 bu1 imi extending far down the stem. It is usually found on debris 

 or mi very rotten logs in forests. Kicken considers it identical with 

 /.. serrulata.
