JONES ON THE IRISH LICHENS. 129 



LicniNA (Ag.). 

 No. 7.— Lichina confinis (Ag.). Barclay's Eock, Co. Down. T.J. 

 Both forms. 



No. 8. — Lichina pygmcea (Ag.). Barclay's Kock, Woburn, Co. Down. 

 T.J. 

 Both forms, but spores not satisfactorily 

 seen. 



Melanotheca (Fee). 



*No. 258. — Melanotheca gelatinosa (Chev.). 



Mudd gives this plant (see his Sp. No. 

 232) asArthonia punctiformis, v. olivacea 

 of Ach. I have ascertained its name 

 through Nylander. 



Myriospora (Repp). 

 *No. 173.— Myriospora Heppii (Nag.).— Sheep walk, Armagh. J. T. 



This plant continues to the end in form a 

 Gyalecta, having spores numerous; on 

 which account, perhaps, it has been re- 

 ferred by authors to Lecanora cervina. 

 As I have found this form in Kent, I 

 use Nageli's name.* 



Nephroma (Ach.). 



*No. 242. — Nephroma lsevigatum (Ach.). Old Dromore. T. J. 



No. 309.— Lough Tay, Co.Wicklow. T. J. 



This is a remarkable form. It covers the 

 stones still washed by the water in sum- 

 mer, and must in winter be three feet 

 under water. As it never fruits, a doubt 

 may remain as to the genus. In its 

 fresh state, the yellow colour of the in- 

 terior of the thallus is decided and dis- 

 tinct, and no doubt it is the form referred 

 to by Nylander. f
