228 THE FLORA OF HALIFAX. 



Collema melsenum, Ach. 



Forma marginale {Lichen decumbens, Huds. I., p. 449.) 

 1775. /. Bolton, Cat. No. 350. 



Sphaerophoron coralloides (Lichen globosus, Huds. I., p. 460.) 

 1775. /. Bolton, Cat. No. 389. 



Lecanora conizsea, Ach. lL. Intescens, Leight., ed. Ill, p. 184). 

 J.A.M. considers the lichen so common on the trees in 

 Pecket and other woods, recorded as L. vavia on p. 224, to 

 be L. conizczoides, Nyl., and the one on bilberry stems to be 

 L. conizaa, Ach. He remarks, "so far as I can see L. 

 conizceoides hardly deserves separating from L. conizcea, but 

 the thallus is more granular and the margin of the 

 apothecia rather different. It is, as it were, intermediate 

 between L. varia and L. conizcea." 



Crombie (Lich. Brit. 1870) places L. conizcea among the 

 varieties of L. vavia. 



In addition to Mr. Hebden's aid in compiling the above 

 list of lichens, Mr. J. A. Martindale, of Staveley, near Kendal, 

 was consulted respecting the elucidation of a few of the more 

 obscure connections between the names as given in Hudson's 

 Flora Anglica, Ed. I. (1762), Ed. II. (1778), Bolton's list (1775), 

 and the modern synonyms employed in Leighton's Lichen 

 Flora. Unfortunately, this was after pp. 215-216 were in 

 print. Mr. Martindale, at once, kindly undertook an indepen- 

 dent revision of the whole of Bolton's list of 83 species. This 

 has enabled us to incorporate 81, along with a few most 

 valuable remarks anent certain of them ; and we here give 

 him our most hearty thanks. 



It is rather remarkable that, of the 85 species contained in 

 the first edition of Hudson, Bolton should have met with no 

 fewer than 83 in the parish of Halifax. Doubtless he sent 

 Hudson specimens of most, if not all, of the lichens he col- 

 lected, and he is thanked, along with five or six other botan- 

 ists, by Dr. Hudson, in the preface to both Eds. I and II of 

 his Flora, for great assistance rendered in their produc- 

 tion. — C. C.
