The elaters vary in length in different gatherings ; usually they are 
long and taper only towards the ends ; sometimes they are short and 
somewhat fusiform, and either simple or branched. The warts on the 
spores may be scattered, numbering eight to ten in a line across the 
hemisphere, or more crowded ; in some American specimens the spores 
are closely reticulated on one side, and spinulose on the other. The 
white and rose-coloured plasmodia have not been observed growing 
together on the same piece of wood, but the sporangia produced from 
both appear to be identical in every respect ; although shades of 
difference occur in various gatherings, the colour of the plasmodium 
cannot be inferred from the ripe fruits.

combined in clusters, 0"6 to 0'8 mm. diam., red-brown, purple, 
or black, often marked with paler lines of dehiscence ; mass o£
