Parmelia.] LICHENES. M9 



The variety (if it be not quite distinct) most common in Kerry, differs 

 from the English Botany figure, in having the segments of the lobes 

 rounded, short, never linear ; nor are the collections of buds situated 

 on short proper lobuli. Although the mode of budding described is 

 very common and characteristic, yet it likewise occurs in minute cup- 

 shaped eruptions on the surface of the thallus. Apothecia are some- 

 times found on Dunkerron mountain an inch in diameter ; on their 

 backs and edges the buds reappear. 



29. P. speciosa, ACH. Thallus stellated, smooth, glaucous- 

 grey, white beneath; the segments flattish, linear, short; the 

 buds terminal and marginal, in coarsely powdery brownish-grey 

 collections ; apothecia very concave ; the border wrinkled and 

 crenate. Ach. L. Un. p. 480. Eng. Bot. t. 1979. 



On mosses, on rocks, and on stems of furze and of heath near the 

 ground ; common : the apothrcia not very rare, near Dunkerron, 

 County of Kerry. The buds usually issue from the terminal edges of 

 the lobes ; yet sometimes they form a dense thick collection in the cen- 

 tre of the thallus : the buds are observed to expand into new fronds on 

 the backs of the aged apothecia. A smoothness of the upper surface, 

 and multifid lobes with short linear segment?, is very characteristic of 

 this species. 



30. P. incurva, ACH. Thallus stellate, of a pale sulphur 

 colour; segments linear, very narrow, multifid, rather convex; 

 buds in terminal and superficial roundish, whitish-yellow, pow- 

 dery collections : apothecia minute, the border inrlexed. Ach. 

 Lich. Suec. Prod. p. 107. P. recurva, Ach. L. Un. p. 490. Eng. 

 Bot. t. 1375. 



On rocks, on Dunkerron mountain, common ; the apothecia rather 

 rare. The hemispherical buds are somewhat whiter than the surface of 

 the thallus ; the central parts of the frond usually turn dark. In our 

 specimens the apothecia, from their minuteness, are invisible to the 

 naked eye. 



31. P. sinuosa, ACH. Thallus orbicular, stellate, of a sul- 

 phur-grey ; segments dichotomous ; sinuses of the lobes circu- 

 lar; buds terminal and marginal, in sulphur-grey finely- pow- 

 dery collections ; apoihecia with a thin incurved crenate border.

On rocks at Glencar, with apothecia, Mr. Joseph Taylor. On Dun- 

 kerron mountain the apothecia were again repeatedly found. I suppose 

 it is scarcely necessary to attach a mark of doubt to the synonymn of Z. 

 dcedaleus of Eng. Bot. The young apothecia are sometimes brown at the 

 border, and even some way down the exterior surface ; this also occurs 

 in P. saxatttis, in P. omphalodes, in P. proboscidea and in P. lesvigata; 

 a state that probably caused our species to be considered a Placodium.
