Collema lacerum, Ach. E. Bot. 1982. On walls, near Mulgrave 
Castle ; old mossy trees, Baysdale, and Oggeray Gill. 
Collema muscicola, Ach. E. Bot. 2264. On rocks partly covered 
with moss, Lanbraugh Rigg. 
Collema spongiosum, Ach. KE. Bot. 1374. Among moss in a 
ravine on Guisbro’ Moor; Battersby bank. 
It must not be considered that the above are all the lichens that 
this district produces: many species are yet under examination ; and 
I hope at no distant period to lay before the readers of the ‘ Phytolo- 
gist’ many additional species. 
It will, no doubt, be observed that I have followed no particular 
arrangement ; my reasons for doing so are, that Fries’s ‘ Licheno- 
graphia Europea Reformata’ is but little known to British botanists, 
and the works by the Rev. W. A. Leighton are not yet completed. So 
far as they are published, [ have followed the names of the latter gen- 
tleman, believing they will be eventually adopted. The remainder 
are from Fries’s ‘ Lichenographia’ and ‘ English Flora.’

Errata.—In my article in last month’s number, I find two typo- 
graphical errors, which I am desirous of correcting. Page 73, for 
“ Arthonia lucida” read “ A. lurida, Ach. ;” and p. 74, for “ Biatora 
perusnea” read “ B. premnea.”
