98 ADDITIONS TO THE BRITISH LICHEN-FLORA. 



Zi. elat'ma, Ach. L. U. 387. On the trunk of holly in subalpine 

 districts. Apparently very rare and local, having been met with only 

 very sparingly at Killarney in Ireland (Carroll), though from its 

 general resemblance to states of Lecidea luteola, it may have been else- 

 where overlooked. 



Lecidea pldcatllis, n, sp., Leight. Ann. and Mag. Nat. Hist. 1869, p. 

 201. — On schistose, mountainous rocks. Kare and local, having been 

 gathered but sparingly on Cader Idris (Leighton), though it is likely 

 to occur also on the Western Grampians of Scotland, 



L. vermifera, Nyl. — This, in my Enum. was by mistake given as a 

 subspecies of L. Jwlomelena, Hepp., instead of L. holomelena, Flk, = 

 L. pelidna, Ach. 



L. resin^e, var. rubicundiila, Mudd, Man. 189. — This from a speci- 

 men in Herb. Brit. Mus., and according also to Leighton, is evidently 

 the same as L. tantilla, Nyl., and is therefore to be regarded only as a 

 synonym of the latter species. 



L. squalida, Ach. L. U. 169. — On the ground in crevices of cal- 

 careous rocks in mountainous districts. Apparently rare and local, 

 having been gathered only very sparingly on the north-western slope 

 of Morrone, Braemar (Crombie), and externally resembling states of 

 L. bacilli/era, Nyl. 



L. inlerludens, n. sp., Nyl. in Flora, 1870, p. 35. — On schistose 

 boulders in alpine regions. Rare and local near the summit of Mor- 

 rone, Braemar (Crombie). This new species is allied to L. mollis, 

 Whlnb., from which it is distinguished chiefly by its apothecia being 

 convex, immarginate, or with a white epithaliine margin, colourless 

 within, as well as by its large elliptical spores. 



L. contigua, var. notabilis, Nyl. Scan. 225. — On quartzose rocks in 

 shady places in subalpine tracts. Apparently rare, having as yet been 

 gathered only on the lower wooded slope of Morrone, Braemar (Crom- 

 bie), but Avill no doubt occur also in other parts of that district. 



L. amphibia, Frs. L. Eef. 307. — On schistose, mountainous rocks. 

 Perhaps not uncommon, though as yet found only on Cader Idris 

 (Leighton), and not readily distinguished from states of L. contigua 

 and its allies. 



L.jurana, Schser. Enum. 123. — On rocks and Avails in mountainous 

 districts. Probably not unfrequent, as on Cader Idris (Leighton), and 

 at Castleton of Braemar (Crombie).
