THE LICHENS OF SOUTH LANCASHIRE. 105 
In the List four species and two varieties new to science are described, 
namely, Bacidia latebricola, Bacidia salicicola, Bacidia epiphylla, Microglana 
nuda, Bacidia arceutina var. brevispora, and Bacidia muscorum var. atriseda. 
The two following varieties, namely, Peltigera canina, Hoffm., var. palmata, 
Duby, and Beomyces rufus, DC., var. Prostii, Duf., which, we believe, have 
not previously been recorded in the United Kingdom, have been discovered 
in South Lancashire during our investigations. 
We desire to acknowledge the kind assistance of Miss A. Lorrain Smith, 
F.L.S., of the British Museum, whom we have consulted on several occasions 
in regard to the identification of material; and we have also to thank Herr H. 
Sandstede for examining some of our Cladonie. We desire also to express 
our thanks to the following gentlemen who have helped us by collecting and 
sending us specimens, or in other ways, namely: A. A. Dallman (Liverpool), 
G. Н. Hopley (Brinseall), C. В. Ritchings (Burnley), Н. Robinson (Colne), 
С. В. Travis (Liverpool), W. Watson, B.Sc. (Greenfield), К. Williamson 
(Rochdale), and A. Wilson, F.L.S. (Garstang).
