TRICHIA.] TRICHIACE^. 171 



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 Unes of dehiscence ; mass of 

 elaters and spores yellow-brown, orange, or reddish-brown ; spo-
