658 LICHENES ANTARCTICI. 
separate, erect above. Apothecia often conjugate with a ter- 
minal branch. There is no space between the surrounding 
cortical part and the hard and horny avis, so as to exhibit 
the longitudinal internal thread peculiar to this genus. This 
space is not so entirely obliterated in U. melaxantha, Ach., 
which has the greatest affinity with the present fine species, 
but which is easily recognised by its scabrous branches and 
granulate backs of the apothecia. The blackening of the 
tips of the ¢hallus is perhaps owing to the attack of a minute 
Spheria of that colour. This Lichen is the handsomest of 
the vegetable productions of this the Island of Desolation. 
150. U. angulata, n. sp.; thallo cinereo pendulo elongato 
filiformi anguleto pinnato cortice minute transversaliter 
rupto fibrillis brevibus teretibus horizontalibus confertis, 
gemmis minutis granulatis demum compressis.

More than a foot long. The principal stem has the bark 
broken across into minute pieces, each with a projecting 
ridge in the same line to the next, and so the entire ap- 
pears angulate. This differs from U. florida, Ach., by its 
pendulous: filiform, elongated and pinnated thallus, by the 
angulated principal stem, and the minute buds. No apothecia 
were found.
