It resembles the small sulcate-striate Coprini, but the lamellee 
do not dissolve. 
Genus —COPRINUS yr. 
Gills membranaceous, deliquescent, spores black.— Berk. 
Outl. 
The species of this genus are readily known by the lamellee 
soon dissolving into an inky fluid. They are quite ephemeral, 
many of them not continuing beyond a single day. Specimens 
are preserved with difficulty, these plants being fragile as well as 
perishable. The inky fluid from the lamelle, after being boiled, 
is sometimes used as ink. The larger species may also be made 
into a catsup.
