412 Mr. Hardy on Lichens of the Eastern Borders. 



46. Lopadium, Koerher. 

 1. L. Fusco-LUTEUM, Dicks. "Upon Cheviot and Hedgeliope." Winch. 

 This I have repeatedly sought for vyithout success. I have it from Ben Lawers 

 from the Rev. H. Macmillan. 



47. Eiatorella, De Notaris. 



1. B. PRCINOSA, Sm. On calcareous spar at Humhleton Mill ; and on 

 quartz veins in Chesterhill rocks. B. On limecoped walls, PenmanshielWood, 

 and on conglomerate and red sandstone near Greenheugh. Dr. Lindsay also 

 found it along with Rhizocarpon petrceiim, in microscopically examining for me 

 some of the numerous acrustaceous apothecia that spot the small fragments of 

 stone that bestrew the roads in Penmanshiel Wood. 



^. EEGULARis, Khr. B. On red sandstone above Swallow Craig, near Siccar 

 point. Sarcogyne regularis, Koerber, Syst. L. G. p. 267. 



48. PyrrllOSpora, Koerher. 



1. p. QUEBNEA, DifA-*. Bark of old trees. N. On oak and alder on the 

 Lill-burn ; on oaks above Coldgate Mill, on the College, and at Koutin Linn, 

 but not in fruit. B. On oaks, birches, spruce-firs, and hollies, Penmanshiel 

 Wood, Ewieside, Bowshiel dean, with apothecia. 



49. Lecidea, Ach. 



1. L. KCPESTEis, Scop. On rocks chiefly those with calcareous constitu- 

 ents. N. Sandstone, Ratcheugh ; on porphyry and calcareous spar, Humbleton 

 Mill. B. On altered greywacke below the "Deil's Dander," Coldingham ; on 

 conglomerate near St. Helen's Church ; on sandstone near Linhead Linn ; and 

 on greywacke. Black Craig, Pease dean. 



7. viRiDiFLAVESCENS, Wulf. On saudstone near Cockburnspath Tower. 

 As Fries remarks ; on the harder stones the apothecia are superficial, on the 

 softer sub-immersed. 



2. L. CONGLOMERATA, Hcyd. N. On bark at the base of hazels in a Avood on 

 the Lill-burn, rare. This has nearly the usual appearance of the species. B. 

 With the thallus the same, but the fruit very imperfect, and globular, some- 

 times pale red, while in some spots it is black. It runs off to an adjacent stone, 

 and then is rather too like BUimUa splicer aides, but the apothecia are smaller 

 and neater, and more regularly dispersed, and the thallus maintains its grey- 

 green colour when dried. It does not appear to be the var. dolosa of B. 

 sphceroides, with which I have compared it. 



3. L. EFFUSA, Ach. B. In shady woods on the trunks of old trees, generally 

 about their bases, where it becomes mixed with Biatorina pineti. About the 

 base of alders, birches, and larches, in the deans in Penmanshiel Wood ; on 

 alder, Brockholes dean. It is best seen in winter and spring. When fresh it' 

 is of a fine dark green. 



4. L. PRASINA, Fries. On the timber of the stocks of old decayed trees in 

 shady woods. B. Stumps of oak in Red Clues Cleugh, in Bowshiel dean, and 

 at the Retreat ; on decaying wood of various kinds, Penmanshiel Wood. N.
