NEW LICHENS FROM KEROTJELEN LAND. 

 By the Ret. J. M. Ceombie, F.L.S. 



In the very interesting collection of Lichens made by the Rev. A. 

 E. Eaton, during the stay of the Venus Transit Expedition in the 

 above island, and submitted to me for examination, there occurred a 

 considerable number of species with which I was quite unacquainted. 

 These, which proved to be new to science, were kindly determined by 

 Dr. Nylander, from whose notes I at present extract the following 

 short diagnoses. 



1 . Parmelia stygiodes, Nyl. Resembling P. stygia (minor), but 

 more contracted, with thallus chesnut- brownish, subopaque (medulla 

 K-|- yellow) ; apothecia with entire thalline margin ; spores not seen 

 rightly developed. Saxicole. 



2. Amphidium molyldophceum, Nyl. Thallus greyish leaden- 

 coloured, astroideo-fissured, in the centre paler and areolato-diffract ; 

 apothecia red or brownish-red, lecanorine, submoderate, with pale- 

 white, subentire margin ; spores suboblong, irregularly 3-septate ; 

 hy menial gelatine bluish, and then wine-red with iodine. Saxicole. 



3. Psoroma hirsutuhim, Nyl. Apothecia reddish-brown, concave.
