CONTRIBUTIONS TO BRITISH LICHENOLOGY. 
By Isaac CARROLL, Esq. 
(Continued from Vol. V. p. 260.) 
This list may serve to show how far the Killarney district appears to 
be from exhaustion. Of rare Lichens previously found, I may observe 
that Lecidea pulverea, Borr. (of which Phialopsis livida, Mudd, appears 
to be merely an undeveloped state), Melaspilea amota, Nyl., Gomphillus 
calicioides, B. microcephalus, Tayl., and Fi errucaria* glabratula, Nyl., are 
frequent ; Acthonia anastomosans, Ach., and Thelotrema subtile, Tuck., 
are less so. Several species, as Arthonia ilicinella, Nyl., and Verrucaria 
desistens, Nyl., I did not succeed in refinding, but this may be attri- 
buted to the shortness of my stay, and the minuteness of many of the 
rarer Lichens.
