122 MESSRS. J. А. WHELDON AND W. G. TRAVIS ON 
LECIDEACE,E. 
GYALECTA CUPULARIS, Schaer.  (Lecidea marmoreus, With.) 
Plentiful on decayed moss on the mortar of an oid limestone wall, 
Downham, May 1910 ; also on shady, damp limestone rocks, Worsaw 
Hill, Chatburn ; probably not uncommon in that neighbourhood. 
This lichen rarely occurs on any substratum except bare rock, and in regard to the 
first-named locality, № may be mentioned that there is a variety growing in such 
situations on the Continent which is distinguished by its paler apothecia with entire 
border and known as var. marmorea, Ach. Our specimens from Downham agree very 
well with this variety, which has not hitherto been described as British. 
LECIDEA LURIDA, Ach. 
On earth among limestone rocks. With us this species is limited to 
the limestone area in the Ribble Valley, and is not uncommon in the 
quarries and on rock outerops about Clitheroe and Chatburn. 
LECIDEA LUCIDA, Ach. 
| On sandstone rocks and walls. Rare. Sterile. “ First noticed by 
Sir J. E. Smith [in 1804], growing on hard sandstone rocks about 
Liverpool," Eng. Bot. 2nd ed. (1846), vol. x. p. 77 ; cf. op. cit. ed. 1,
