118 FUNGI. 



species Russula are gems of brilliant colouring. The golden 

 tufts of more than one species of Clavaria are exceedingly 

 attractive, and the delicate pink of immature Lycoyala epiden- 

 drum is sure to command admiration. The minute forms 

 which require the microscope, as much to exhibit their colour 

 as their structure, are not wanting in rich and delicate tints, 

 so that the colour-student would find much to charm him, and 

 good practice for his pencil in these much despised examples of 

 low life. 



Amongst phenomena might be cursorily mentioned the 

 peculiar sarcodioid mycelium of M^yxogastres^ the development 

 of amoeboid forms from their spores, and the extraordinary 

 rapidity of growth, as the well-known instance of the Eeticularia 

 which Schweinitz observed running over iron a few hours after 

 it had been red hot. Mr. Berkeley has observed that the creamy 

 mycelium of Lycogala will not revive after it has become dry 

 for a few hours, though so active before.
