178 , ADDITIONS TO Til H BRITISH LICHEN-FLORA. 



Sticla ciliaia, Tayl. Fl. Hib. 2, 152. This, according to authentic 

 specimens iroin Taylor in Herb. Brit. Mas., is only a muscicole state 

 of Slicta Biifourei ; and, indeed, as appears from one of the above 

 specimens, Taylor was latterly aware of its being only a var. of S. 

 aylcatlca. 



Lecu)iora pldofi'iita, Ach. ? Nyl. L. P. 121; Placodinm c'drinellum, 

 llcpp. Flecht, 393. On Oak-bark in lowland maritime tracts. Kare, and 

 gathered but very sparingly near Fairlight, Hastings (Crondjie), though 

 it may be expected to occur elsewhere in the south of England. 



//. Parkiensis, Nyl. Jard. Luxemb. p. 368. On the trunks of trees 

 in lowland tracts. Apparently local, as near Shanklin, Isle of Wight 

 (HoU) ; though [ have seen specimens from various localities in the 

 south of England closely approaching it, but not suihciently typical. 



L. atriseda (Frs. L. Kef. 149), Nyl. Scan. 170. On schistose moun- 

 tainous rocks. Hare, and gathered only ne ir Dolgelly, in Wales (HoU). 

 It is closely allied to L. badia, of which Fries regarded it as merely a 

 variety, 



L. scriiposn, var. par mi tic a, Smmrf. Lapp. 100 {ecnisfacea, Nyl. 

 Prod. 96). Parasitic on thallus of Cladonia, pyxidata. Not common in 

 subalpine tracts, as ou old Ash-trees in Glen Lochay, Breadalbane 

 (Crombie). 



Dlrlnn re/)ri)ida, Frs. S. 0. V. 285. On rocks in maritime tracts. 

 Earc, and local in the Channel Islands on coast of Hcrm (Larbalestier). 



Lecldea pnrissima, Nyl. in litt. sp. n. On old pales in damp shady 

 places in lowland tracts. Apparently rare and local, near Hendon, 

 Middlesex .(Cr()nd)ie). It is closely allied to some states of L. dotif/rata ; 

 but amongst other marks of distinction has the hymeneal gelatine yel- 

 lowish wine-coloured, and not bluish with iodine. 



L. encUtica, Nyl. Lapp. Or. 148. On old fir-pales in subalpine tracts. 

 Perhaps not very rare, though as yet gathered only sparingly in Glen Tilt, 

 Blair Atliole (Crombie) ; but from the small size of the apothecia, and 

 their being so much scattered, it may have been overlooked elsewhere. 



L. endopdla, Leight. in litt. sp. n. On fir-pales in subalpine ti'acts. 

 Rare in Glen Fender, Blair Athole (Crombie, August, 1870). It is allied 

 to the preceding, from which it is distinguished chietly by the larger 

 and crowded apothecia, and the spores having two rathei' large nuclei. 



L. melonochroza, Leiglit. in litt. sp. n. On decaying tir-pales in sub- 

 alpine regions. Rare and local, near Loch Tummel, Perthshire (Crombie, 

 August, 1870). The thallus is almost furfuraceous, and the apothecia 

 internally pale violet-black, as if stained with ink. 



L. alociza, Mass. Symm. 42. On calcareous rocks in subalpine tracts. 

 Perhaps not uncommon in hilly regions, though as yet gathered only near 

 Buxton, Derbyshire (Holl.), and, at first sight, not to be distinguished 

 from other externally similar species. 



L. Bonteillei (Desmaz.), Nyl. Lapp. Or. 152. On box-leaves in ma- 

 ritime tracts. Apparently local in the Channel Islaiuls, as in Jersey 

 (Larbalestier), and also in the south of England, as near Hurst in Sussex 

 (Da vies). 



L. snblatypea, Leight. in lilt. sp. n. On micaceous stones of walls in 

 mountainous regions. Very sparingly in Glen Fender, Blair Athole 

 (Crombie, August, 1870). Externally it very much resembles states of 

 Z. latypca ; but the thalline reaction (K — ), as well as other minor cha- 

 lacteristics, show it to be distinct.
