5. U. angulata, Hook et Tayl, Central axis I — ; med. fib. 



K — C — . 



Thallus ashy white, pendulous, elongate-filiform, angulate- 

 pinnate, cortex minutely and transversely cracked ; fibrils 

 short, terete, horizontal, crowded ; gemmae minutely granu- 

 lar at length flattened. Over one foot in length. Differs 

 from U. florida Ach. by its pendulous, filiform, elongated 

 and pinnated thallus, by the angulated principal stem and 

 M the minute gemmae. Apothecia large, to 15 m.m. ; spores 

 •005 x -004 oval or subspherical ; thecae "025 — *03 m.m. 

 long, Stirton says — " Central axis thick, dense, solid, 

 nearly as in U. longissima but I — ; medullary fibres white,, 

 forming a thin layer surrounding axis (K — C — ).

6. LT. dasypoga, Fr. (K— I— ). 



Thallus whitish, elongate, pendulous, fibrillose , the primary 

 branches terete, thick, solid, smooth, the medullary fibres 

 compressed, with stigmata at intervals ; secondary branches 

 K often longer than the primary ones, and nearly as thick, 

 ungraceful, almost straight ; tertiary branches few, abruptly 

 acute.

 reddish-yellow colour, smooth, glabrous, with secondary bran- 

 K ches reaching to apices of primary ones, lightly fibrillose except 

 on the main stems, a fact which distinguishes it from U. 

 trichodea ; tertiary divisions few, close, transversely fissured.

 with 8 — 10 setae in the ray.
