tufts of more than one species of Clavaria are exccedingly 
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 Myzxogastres, the development 
of amoeboid forms from their spores, and the extraordinary 
rapidity of growth, as the well-known instance of the Reticularia 
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.
