ADDITIONS TO THE BRITISH RAMALINEI. 
8 . R. Curnowii. Cromb. 
On maritime rocks. S.W. England. 
As observed by Nylander, in “ Flora,” 1877, p. 562, this 
descends from R. cuspidata. 
9. R. geniculata. Tayl. 
On thorns. Killery Bay, Connemara. 
This is a very interesting discovery by Mr. Larbalestier of a 
plant formerly known to occur only in exotic regions. 
10. R. minuscula. Nyl. 
On the branches of stunted larches. Craig Cluny, Braemar, and 
probably also elsewhere in that district. 
11. R. intermedia. CBel.) 
On stems of heath and shrubs. Scilly Islands and Galway, &c. 
Sparingly fertile. 
Note on Lecidea farinaria. Borr . 
In “ Sm. E. B.” Suppi. II., t. 2, 727, Mr. Borrer described a plant 
under the above name, which has hitherto not been identified by 
any subsequent lichenist. Schaerer, in his “ Enum.,” p. 138, 
doubtfully refers it to Lecidea granulosa var. aporetica, Ach. Of 
this latter there is no specimen amongst the Lichens sent by 
Acharius to the Linnean Society, nor fide Fries fil. (Lich. “ Scand.,” 
p. 443) are there any in his own Herb, now in the University of 
Helsingfors. I believe, however, that it is merely a corticole and 
lignicole state of Lecidea decolorans , such as I have gathered on 
Craig Calliach, &c. (not var. aporetica , Cromb., Exs. n. 81, which 
is Lecidea viridescens , Schrad.). Unfortunately, also, there is no 
named specimen of Lecidea farinaria in Hb. Sowerby. A speci- 
men, however, from Borrer himself occurs in Hb. Salwey, which in 
appearance exactly corresponds with the figure and description in 
E. B. S., and with an unnamed specimen in Hb. Sowerby. There 
can thus be no doubt as to the identity of this previously most 
uncertain species. It is also the plant named by Nylander 
Lecanora homopis, Nyl. = Cromb. Exs. n. 163, which is, there- 
fore, with strict propriety to be called Lecanora farinaria (Borr.). 
It is very common on old pales in the north of Middlesex and 
south of Hertfordshire, though often sterile.

Note on Bacidia Arnoldiana. Korb. 
In Koerber “Par. Lich.” II. (1860), p. 134, a well-marked species 
of Lecidea is described under the above name, in compliment to 
the distinguished Lichenist, Dr. Arnold. Previously to this how- 
ever, Krempelhuber, in “ Flora,” 1855, p. 72, had described 
another species, s.n. Biatorina Arnoldi, Kphb. As in the Nylan-
