186. — C'oprinus macrorhizus. Development of a set of fruit-bodies with very long 

 pseudorhizae, shown in a vertical section through a pile of stable manure. At the base of 

 the Figure is more solid manure from which the pseudorhizae are springing ; toward the 

 top, the manure is looser and the straw more evident. Stages in development, drawn from 

 actual specimens, are indicated by the letters a to/. In a, b, and c, the blunt upper end 

 of each pseudorhiza consists of a rudimentary pileus, already with tiny gills within ; ind, 

 e, and/, tlie pseudorhiza, tlirough intercalary growth, has brought each pileus to the surface 

 of the substratum. At d, the pileus is swelling ; at e, the pileus is expanding and the 

 aerial stipe-shaft elongating ; at/, the stipe-shaft is fully elongated and the pileus, which 

 has shed its spores, is now greatly reduced owing to autodigestion. Natural size.
