One of the most widely diffused species throughout the Southern Hemisphere ; though variable, its limits are 
well defined. Its nearest ally is the beautiful C. retipora, Lab,

Has. Lord Auckland's group and Campbell's Island; on the branches of shrubs, very abundant. 
Acharius cites “Staten Land ” as the habitat of this species; we have never seen specimens from the American 
Continent (the Cape Horn station quoted in the * Lond. Journ. of Bot.” being erroneous), whence it is possible that 
the author may refer to another plant; we have, however, followed our friend Montagne, who gives this name to 
his beautiful plate of our plant. 
2. Sricra foveolata, Delise, Monogr. de Sticta, p. 101. t. 8. f. 36. Mont. in Voy. au Pole Sud, Bot. 
Crypt. ined. S. linearis, nobis (in part), Lond. Journ. of Bot, vol. ii. p. 647. 
Has. Lord Auckland's group; on the trunks of trees. 
Except in being of a rather larger size, this does not differ from a copious suite of specimens which we have 
examined from Tasmania. The apothecia are variable, generally with the disk flat, but sometimes concave, and in 
these specimens very much so. In both this and the 5. Billardieri, which seems hardly distinct from it, the border 
of the apothecia is often evanescent.
