Phialea aquatica, Sacc., Syll., viii. n. 1105. 



On fragment of stick in water. 



Type specimen examined. 



The fruit is large for the size of the plant. I cannot 

 remember the colour of the disc, having unfortunately 

 omitted to make a note of it, and the specimens having been 

 kept in spirits, have turned quite black. (Currey.)
