lime, flowed; Dunkerron Mountain. Dr. Taylor in Herb. Moore. 

 This species is also present in a small collection sent to Dr. Hincks by 

 Miss Hutchins, and now in the Royal Cork Institution. 



3. Z. lutea (Schar.). Lichen luteus (Dicks.). On trees, Dunker- 

 ron ; Dr. Taylor in Herb. Moore. Glenarm, Co. Antrim, Moore. Near 

 Cork and Killarney. 



4. Z. pineti (Ach.). (Nyl. L. P. Exs. 56!). Lecidea pineti. p. minor 

 (Schcer., L. H. Exs. 2181). Gyahcta? pineti. (Leight, L.B. Exs. 89!). 



On Pinus sylvestris (Z.) near Larne; D. Moore. In Lord Aldbo- 

 rough's demesne at Baltinglass, Co. "Wicklow, and near Cork, where I 

 have also observed it on an apple-tree. 



5. Z. lurida (Ach.) t (Schccr. L. H. Exs. 157! Nyl. L.P.Exs. 131!). 

 On limestone near Gal way; D. Moore. Vide Plate XXIX., Figs. 1, 2, 

 a, b, e. 



6. Z. sublurida (Nyl. MSS.). On sandstone and slate rocks. Spe- 

 cimen marked Lecidea lurida in Herb. Cork Inst., collected by Miss 

 Hutchins. Rocks near Belfast and on Island Magee, Co. Antrim ; D. 

 Moore (vide Plate XXX., Fig. I, a, b, c). Brandon Mountain, Kerry; 

 D. Moore. Crevices of rocks by the sea at Ballycotton, Co. Cork. Plate 

 XXXI., Fig. 2, a, b y c y d. This fine species, the distinctive characters 

 of which I was the first to point out, may be recognised from Z. lurida 

 (Ach.), when growing, by its larger size and paler colour, but more cer- 

 tainly by the appearances presented on dissection. It is allied, Kylander 

 says, to Z. rufonigra (Tuck) of N. America. 



7. Z. glaucolepidea (NyL MSS.). M Thallo glauco, squamulosa ; 

 found on the top of a mountain, Ireland, 1812. Miss Hutchins, in Herb. 

 Hooker" (NyL in litt.). About the roots of heath, on a moor, four 

 miles from Ballintoy, Co. Antrim; D. Moore. Plate XXXI., Figs. 2, 3, 

 «, b, c. This cannot be confounded with any other British species. 



8. Z. mutabilis (Fie y fide Nyl.). Thallus whitish or glaucous ; apo- 

 thecia reddish-brown ; spores simple ovate, rather large. On the bark 

 of young trees in a very few localities in Co. Cork, as at Castlebernard 

 Park, Bandon, where Admiral Jones has also found it. On holly, Black- 

 water Bridge, Kerry. This species, according to Nylander, is new to 

 Europe, having hitherto been found in North America only. Vide Plate 

 XXIX, Figs. 2, 3, a y b } c. 



9. Z. Lightfootii (AcK\ var. minor (Nyl. in ML). L. commutata 

 (Ach. fide W. Mudd, who thinks it a distinct species). On young trees
