PANNARIACEZE. 
PANNULARIA NIGRA, Nyl. 
Not unfrequent on bare limestone rocks and walls, but confined to the 
Carboniferous limestone in the Ribble Valley. Specific localities which 
may be mentioned are: Worsaw Hill and other places about Chatburn, 
Bellman Hill near Worston, and walls by the roadside between Chatburn 
and Downham, С. B. Travis $ W. G. T. 
LEPROLOMA LANUGINOSUM, Nyl. 
Shady calcareous rocks. Rare. Fruit unknown. In a gully on the 
north side of Pendle Hill, alt. 850 ft., June 1908, A. Wilson ; Worsaw

Extinct. This old record may possibly refer to U. ceratina, Ach., 
var. scabrosa, which still occurs on trees and rocks in the adjoining vice- 
county of West Lancashire. 
[ USNEA ARTIOULATA, Hoffm. 
* Muscus arboreus nodosus sive geniculatus. Knotted or kneed tree 
moss. This T. W. brought to me at Burnley in Lancashire, where he 
found it growing on an Hasell Nut-tree." Ray, Cat. Plantarum 
Anglia, &e., ed. 2 (1677), p. 203. “In Lancastria, prope Burnley, 
pagum e Corylo dependentem invenit Th. Willisell," Лау, Synopsis, 
ed. 2 (1696), p. 22. On beech near Burnley, Dillenius.] 
Long extinct. These are the oldest records of Lancashire lichens that we have ; and 
are eloquent of the vast changes that have taken place in the flora of South Lancashire. 
Usneas still linger sparingly in West Lancashire, but in South Lancashire the whole 
genus is extinct, and has been for at least a generation. 
CETRARIA ACULEATA, Fr. Оп bare, peaty soil on some of the higher hills, 
where it is not uncommon locally ; also, sparingly, on the sandhills. 
Sterile. 
Forest of Rossendale, Stansfield ; on the summit ridge of Boulsworth 
Hill, H. Robinson! ; summit of Pendle Hill, 1830 ft. ; Ainsdale sand- 
hills, 23 March 1898; bare spots on dry grassy dunes, Formby, May 
1913.
