Subsp. cupreiformis Nyl. ex Huo in Rov. Bot. v. p. 92 

 (1888).— Thallus thin, subgrarmlatc-concrescerit, whitish. Apo- 

 thecia reddish-brown or blackish ; paraphyses septate, distinct at 

 the apices; epithecium reddish; spores 0,010-18 mm. long, 

 0,0045-55 mm. thick. — Cromb. in Grevillea xxii. p. 10. L. 

 cuprea var. cupreiformis Nyl. in Not. Sallsk. Faun. & Fl. Fenn. n. 

 ser. V. p. 144 (18G6) ; Cromb. Lich. Brit. p. 68 ; Leight. Lich. Fl. 

 p. 273 ; ed. 3, p. 273. L. vernalis var. ^ cupreiformis Nyl. in 

 Not. Sallsk. Faun. & Fl. Fenn. iii. p. 90 (1857). L. cupreiformis 

 Nyl. in Flora li. 347 (1868). 



Differs chiefly in the character of the paraphyses and in the colour 

 of the apothecia. 



Hab. On the ground in crevices of schistose rocks. — B. M. Above 

 Loch-na-Gat, Ben Lawers, Perthshire (the only locality). 



43. L. ochrococca Nyl. in Oefvers. Vet. Ak. Forh. 1860, 

 p. 297 & Lich. Scand. p. 206.— Thallus effuse, thin, granulose, 

 yellow-ochraceous ; the granules small, firm, contiguous or sub- 

 dispersed (K — , CaCl — ). Apothecia small, sessile, plane, at 

 length convex, reddish or rusty-brown, whitish within, the 

 margin obtuse or indistinct, paler ; hypothecium pale ; paraphyses 

 concrete ; spores oblong-fusiform, 0,007-10 mm. long, 0,003- 

 4 mm. thick ; hymenial gelatine bluish then, especially the asci, 

 wine-red with iodine. — Mudd Man. p. 194; Cromb. Lich. Brit, 

 p. 69 ; Leight. Lich. Fl. p. 261 ; ed. 3, p. 257. 



Well distinguished from all allied species by the colours of the 

 thallus and of the apothecia. It occurs elsewhere only in Norway. 

 The thallus is occasionally evanescent,when the apothecia appear on 

 dealbate parts of the substratum. Our British specimens are well 

 fertile. 



Hab. On the trunks of pine trees in upland tracts of mountainous 

 regions. — Distr. Very local and scarce in the W. Highlands of Scotland. 

 — B. M. Inverouran, Argyll ; Glen Falloch, Ben Lawers, and Black 

 Wood of Kannoch, Perthshire. 



44. L. symmictella Nyl. in Flora li. p. 163 (1868).— 

 Thallus obsolete, developed within the bark (hypophlceodal). 

 Apothecia very small, adnate-sessile, convex, immarginate, at 

 first waxy-yellow, then livid, somewhat shining ; paraphyses 

 colourless ; epithecium granulose, yellowish ; hypothecium colour- 

 less ; spores oblong or oblong-ellipsoid, 0,004-6 mm. long, 0,0015- 

 25 mm. thick ; hymenial gelatine bluish with iodine. — Cromb. in 

 Grevillea xxii. p. 10. Agyrium csesium Fr. Syst. Mycol. ii. p. 231 

 (1823) (non Acharius Syn. p. 171). 



Kesembles an ecrustaceous state of Lecanora symmicta Ach., but 

 from the character of the paraphyses belongs to this section of Lecidea. 

 Though no distinct thallus is visible, yet, as observed by Th. Fries 

 (Lich. Scand. p. 433), gonidial glomeruli are always present among 

 the fibres of the substratum, especially in the neighbourhood of the
