proliferous, curved calices, often 15 centiin. long, not dilated 
at base ; aperture 1 millim. round, lip rather thick, septa six ; 
under surface shows branches and branchlets uniting to form 
irregular and close network almost entirely bare of calices, 
which are immersed ; surface minutely echinulate. Oorallutn 
dense, ends of calices tipped with lilac. 
This species differs from u speciosa ” in having the long 
tubular calices rising from short stems with appressed nari-

From u fragilis” it is quite distinct.
