1S74, p. 16 : Cromb. Journ. Bot. 18S2, p. 274, is accordino; to 

 Waiiiio and Arnold a sterile and less developed state of this plant, 



A very distinct species which at first sight seems near i. oculatn, but, 

 as rightly conjectured by Nylander I. c, from sterile specimens, belonging 

 to this section. The papillae are scattered or here and there crowded, 

 becoming at times entirely leprose. In the very few British specimens 

 neither apothecia nor spermogones, the latter as yet unknown, are 

 present. 



Hab. Overspreading decayed mosses on the ground in alpine places. 

 — Distr. Very local and rare on one of the S. Grampians, Scotland. — 

 B. M. : Ben Lawers, Perthshire. 



N. Apothecia innate, lecanorine or rarely lecideine ; hypothecium 

 Urfually colourless ; spores Snve or QniB (rarely 4ncie or 2nae), 

 simple, colourless ; hymenial gelatine variously tinged with 

 iodine. Spermogones with simple sterigmata and acicular, 

 straight or very rarely arcuate spermatia. {As2yicilia Mass. E,ich, 

 (1852) p. 36 pro parte.) 



a. Gonidial system composed of ordinary eugonidia {Pacliyospora 

 Mass. Rich. (1852) p. 42 pro parte).

 terminate, either minutely granulose with the granules variously 

 subglobose, or plane and arcolato-difFract, olive-brown or brownish- 

 grey (Iv(CaCl) + reddish) ; hypothallus thin, black. Apothecia 

 sessile, small, at length angular or lineari-compressed, black, the 

 thalline margin entire ; spores ellipsoid, 0,017-25 mm. long, 

 0,011-15 mm. thick; paraphyses slender; epithecium and hypo- 

 thecium brownish ; hymenial gelatine tawny wine-red with iodine.

A rather singular plant of this section both as to thallus and apothecia. 

 The subglobose verrucse are usually discrete, and when rubbed are more 

 or less yellow-greenish at the apices. The apothecia are at length as if 

 gvi'oso-plicate, whence Fries (Lich. Eur. p. lol) observed that, if normal, 

 the plant would belong to a distinct genus. Its true systematic place, 

 however, is shown by Nylander, Flora, 1876, p. 2-j3 (cfr. Flora, 1879, 

 p. 204), s. n. Lecannra sophodopsis, under which syuonym the first com- 

 plete diagnosis is given. The British specimens in which neither the 

 thallus nor apothecia are well developed belong to a form puiij>eraia 

 Nyl. in litt. The spermogones are here and there visible, with spermatia 

 straiglit, 0,004o mm. long, 0,0005 mm. thick. 



Hah. On schistose walls in an upland district. — Distr. Only sparingly 

 in N.W.England; no doubt to be detected elsewhere. — B. M. : Near 

 Staveley, Kendal, AVestmorelaud.
