of the typically fnitifulose thalliis, but he now more correctly refers it 

 to the ]'(ir)tu'/ici. Tiie .Mtriirtiire of the apothecia, the presence of rhiziiue 

 yparinjrly in one of tlie species, and other ciiaracters ally it to I'dvnielut, 

 from which, as Nylander observes ( Flora /. c. ), it scarcely differs gcne- 

 rically. Indeeil in I'armclin we have sometimes the same fruticulose 

 habit, as in 1'. Kamfsc/itida/in ; while in the section of P. /i/ii/xof/cs (and 

 the species of Eveniia approach very near to P. vittato) the tiiallus is 

 similarly glabrous beneath.

Varies considerably according to age and habitat, but alwavs easilv 

 recognized. The thallus in old plants is covered with white confluent 

 soredia on the margins, which are sometimes also spaiinglv scattered 

 over the surface of the lacini;^ (form sorediata \c\\.). The apothecia are 

 rai'e in this country, and the sperraogoues <ire also seldom seen. They 

 are externally black, colourless within, with spermatia 0;O0G-7 mm. long, 

 about 0,005 mm. thick. 



Hab. On the trunks and branches of trees, chiefly firs, and on hedge 

 bushes, in wooded upland tracts. — Distr. General and usually plentiful 

 in most parts of Great Britain and Ireland; rarer in the Channel Islands; 

 abundant in old flr woods in the Grampians, Scotland, where also it i«
