margin, and probably includes derivatives of more than one 
species, whilst C. cccspititia is also a somewhat questionable 
species. 
Amongst other minor matters it should be noted that TicJto- 
spora is not a true synonym of Collemopsis ; Stir should be Stiz.; 
Scyphophoreae and Ascyphae (under Cladonia) should be definitely 
indicated as sub-divisions of Microphyllineas ; Floerk. and Koerb. 
when so written ( i.e with the e) do not require the “Umlaut” 
indicated by the two dots above the o ; and some of the authorities 
are wrongly given, e.g., Placodium cnudicans should be referred to 
Mudd and not to Nyl. The compiler of the list has some strong, 
and 1 think warranted, views as to “ the piracy of specific names,” 
but in many instances he has neither adopted the method he agrees 
with, nor that followed by many authors of giving as authority the 
person who first placed the species in the genus. Mr. Macvicar in 
his recent and excellent work on the Hepaticae 1 has followed the 
method of giving the original author of the specific name in brackets, 
followed by the name of the authority for the actual combination of 
the generic and specific names; this method has been used by 
many authors, has the advantage of indicating the history of the 
naming, and avoids any charges of piracy. 
Notwithstanding the necessarily incomplete character of the 
work, the List will provide British Lichenologists with a ready 
means of reference, and thus fill up a gap which has long been felt 
by students and collectors of these interesting organisms.
