This fpecies is fo fingular in its form and mode of growth, that 

 it is impoffible to confound it with any other in the genus. 



At the firft appearance it exactly refembies a Peziza Handing on 

 a fhort thick footflalk, and in this flate has been defcribed by 

 Ray, Syn. p. 43. n. 15, and by others of the older authors by the 

 very apt name of ' Fucusfungis ajfwis? The frond, which arifes from 

 the centre of this pezizseform rudiment, exactly refembies in fub- 

 ftance a leather thong, is without rib or nerve, bears neither leaves 

 nor branches ltrictly to be fo called; but is conftantly dichotomouilv 

 divided at intervals of 3 or 4 inches each, until not unfrequently it 

 attains a length of 2 or 3 yards, and ibmetimes much more ; and the 

 divifions, being in proportion to the length, have been found to 

 exceed twenty or thirty. The breadth, which is originally 3 or 4 

 lines, does not much vary, except towards the extremity, when it 

 becomes narrower and ends in an acute point — The angles formed 

 by the dichotomy are acute. The whole furface of the plant is
