CONTRIBUTIONS TO IRISH 1ICHENOLOGY ! PART II. BY ISAAC CARROLL, CORK. 



Graphis {Ack.). 



1. G. anguina (Nyl.). G. scripta (Leight.,Mon. Br. Graphideae). G. 

 pulverulenta (Leight., ibid.). Common on trees, especially young oak. 



G. pulverulenta (Leight.) scarcely differs from the ordinary form save in 

 its more or less powdery thallus. Opegrapha anomala {Leight.) found 

 " at Glengariff, on holly, by Mr. H.Piggott," appears, from the figure in 

 the " Annals of Natural History" to be also a form of G. anguina (NyL), 

 in which the excipulum is entire, " surrounding the sides and base" of 

 the lirella, as in the genus Opegrapha {Ach.). The spores, ovate or ob- 

 long, " murali-divisce" are alike in all. 



2. G. scripta {Ach.). G. serpentina (Leight, Mon. Br. Graph.). On 

 trees, very common ; varying much in form, but readily distinguished 

 from every state of the preceding by the different spores. Perhaps the 

 most remarkable vars. are the h.jlexuosa of Leight., Mon. Br. Graph., 

 found at Castlebernard Park (Prof. Hincks), and elsewhere, in which the 

 lirella are very long, simple, nexuose, and a form found at Rostellan, on 

 alder, having the lirella slender and branched as in G. dendritica {Ach.). 



3. G. elegans {Ach.). Aulacographa elegans (Leight., Mon. Br. Graph.). 

 Opegrapha sulcata (Pers. Tayl. in Fl. Hib.). On young trees, especially 

 oak ; common in the south of Ireland.
