' COPKIXUS 



Distinguished from all gill fungi by its black spores and dissolving gills. It 

 is related to Bolbitius, which has ocher spores. This genus contains several 

 of the best of all edible fungi, and is fortunately readilv recognized even by the 

 novice. (_)n the second or third day, the caps expand more or less completely, and 

 the gills begin to dissolve, forming a Ijlack inky liquid. As this dries, the gills be- 

 come mere lines. The blackening of the gills begins early, but the caps are good 

 until the gills begin to dissolve. The name refers to the habit of growing on dung 

 or in richly manured ground.
