 The spores easily break from the flocci on which they are 

 supported as if on a peduncle half their own length. Their 

 greatest thickness is usually near the base, the lower part tapering 

 rapidly, the upper, gradually to their respective extremities. Some 

 spores are oblong, others linear. They are seldom strongly curved 

 and this character is not always present even in C caricinum.

 branched, pale, echinulate ; spores globose, minutely rough,
