that this lichen had been already described by her under the above name, and was 
included in the addenda to Mon. Brit. Lichens, vol. ii. p. 352. 
The discovery of this species in Lancashire is of interest, as we understand that the 
clay-pit in which Father Reader discovered it has been filled in and the habitat 
destroyed. 
LECIDEA PARASEMA, Ach. Оп the bark of trees and on decaying wood. 
Rare, and poorly developed. 
Rainford, Vict. Hist. p. 85 ; stumps on the shore, Danks; on willows, 
Woodvale, July 26, 1913 ; near Downham, June 1914, C. В. Travis & 
W. G. T. 
Var. ELÆOCHROMA, Ach. (L. enteroleuca, Ach.) 
On a piece of old pine-bark, sandhills, Formby, April 1913 ; on the 
bark of a holly-tree near Downham, June 1914, associated with Pertu- 
saria leioplaca, Schaer. 
LECIDEA GONIOPHILA, Schaer. 
Occurred, along with Lecanora galactina, on а half-buried stone 
(limestone) in a footpath near Cock Bridge, Whalley, March 1913, 
C. B. Travis & W. G. T. 
LECIDEA CONTIGUA, Fr. On rocks and walls of Millstone Grit and sand- 
stone ; common, especially in the hilly districts, but occurring also, not 
unfrequently, оп sandstone walls in the lowland. It is very noticeable 
on and by water-washed rock-surfaces in the cloughs. Only observed 
by us on siliceous rocks. This species, judging by its frequency and 
its occurrence often close to towns, is fairly tolerant of a smoky 
atmosphere. 
LEOIDEA SOREDIZA, Nyl. Very rare. Sterile. 
On chert, in a small clough or gully above Hook Cliffe, Pendle Hill, 
alt. 700 ft., June 1911. 
LECIDEA CRUSTULATA, Кое. Оп sandstone rocks and loose stones, 
Probably not uncommon in the upland districts. 
Boulsworth Moor, Sept. 1910, A. Wilson! Pendle Hill, alt. 700 ft., 
June 1911; Greens Clough, Мау 1912, С. R. Ritehings $ W. G. Т. ; 
on a half-buried stone in a field, Chatburn, March 1913; Cold Wells 
near Burnley, and on a sandstone wall, Watermeetings near Colne, 
May 1913, H. Robinson $ И’. G. T. ; on clay ironstone nodules on old 
colliery rubbish heaps, near Rainford, July 1914. 
Var. MEIOSPORA, Olivier. Sandstone wall, Aintree, Feb. 1904. 
[ LECIDEA CONFLUENS, Ach. 
Forest of Rossendale, А. Stansfield. } 
We have not ourselves seen this species in our area, and its occurrence 
now is problematical.
