42. Bacidia, Be Notaris. 



1. B. ROSELLA, Pers. B. On old roots of oak trees and bark of birch, trees 

 on the south side of Bowshiel dean ; and on trunks of birch trees, and parasitic 

 on a mass of Hysterium, Penmanshiel Wood ; very rare. 



2. B. CARNEOLA, Acli. B. On the scaly bark of old oaks, Bed Clues Cleugh, 

 and in Penmanshiel Wood near it ; rare. The apothecia at their first origin 

 appear as white warts split at the apex into a cross. Schaerer. 



3. B. LUTEOLA, Ach. 3. FUSCELLA, Frics. N. With var. a., on trunks of 

 ash and alder on the Lill-burn. B. On the trunk of a hawthorn, Dowlaw dean ; 

 and on alders below the Retreat, where the fruit is rare, but the barren thallus, 

 and the spermogoniferous state {^Pyrenothea vermicellifera, Kunz.) is locally 

 prevalent. Abundant in fruit on the decayed bark of a sallow in Kitchen 

 Cleugh, Dec. 1862. 



7. INUNDATA, Fries. On moist stones and rocks in burns, and by water- 

 sides. N. In the Lill-burn and at Harthope Linn ; and among the rocks on 

 Care-burn. B. More common. Whare-burn, Whitadder at the Retreat ; 

 Blackburn-rigg dean; Bowshiel dean; Pease and Cockburnspath ToAver 

 deans, &c. When old the thallus becomes of a dirty griseous white, and the 

 apothecia are blackened ; in this state it might readily be taken for Lecidea 

 contigua ; but on removing the upper lamina of the apothecia, the interior is 

 found to be pale yellow. In its young state it is of a fine emerald green.
