The type was collected on the same host by Heller near Bayamon, 

 Jan. 21, 1903, No. 6435. 



The cylindrical, capitate hypophodia, so crowded as to touch each 

 other, give a unique appearance to the colonies on Allophyllus. Study 

 of the type specimen and my own specimens on Thouinia shows varia- 

 tion in the crowding of the hyphopodia. In some parts of the colony 

 they are densely crowded and opposite ; at the edge of the same colony 

 they may be strictly alternate and sparse.
