34. L. ferruginascens Nyl. Flora, 1S72, p. 427. — Thallus effuse, 

 thin, areolato-diflVact, whitish (K +purplish), often evanescent. 

 Apothccia small, biatoiine, plane and margined, or at length convex 

 and immargiuate, rusty-ochraceous or tawny-fcrrugineous (K + 

 purple) ; spores oblong, polari-bilocular, with longitudinal tube, 

 0,011-16 mm. long, 0,004-6 mm, thick. — Cromb. Grevillea, xviii. 

 p. 45. 



Allied to var. ^ of the preceding species, but differs in the colour of 

 the apothecia and in the spores, which, as observed by Nylander /. c, 

 often appear simple in the recent plant. In the British specimen seen 

 the apothecia become at length rather dark. 



Hah. On schistose rocks in an upland situation. — Distr. As yet only 

 very spai-ingly in N.W. England.— B. M. : Near Kendal, AVestmoreland. 



35. L. fuscoatra Nyl. Flora, 1872, p. 427. — Thallus effuse, 

 thin, minutely areolato-diffract, sordid- greyish (K-f- purplish-violet). 

 Apothecia small, nearly plane, lecanorine, rusty-red (K-|- purplish), 

 the thalline margin distinct, entire; spores polari-bilocular, 0,011- 

 15 mm. long, 0,006-9 mm. thick. — Cromb. Grevillea, xviii. p. 45. 

 — Lecfinora ferruginea var. fuscoatra Cromb, Lich. Biit. p. 47; 

 Leight, Lich. Fl, p, 220, ed, 3, p. 209. Biatora ferruijinea c. fusco- 

 atra Bayrh. Uebers. (1849) p. 82. 



Apparently specitically di.'-tinct from L. ferruf/inca, differing at once in 

 the definitely lecanorine apothecia. Our few British specimens are well 

 fertile. 



Hah. On schistose rocks in maritime districts. — Disir. Only very 

 sparingly in N.W. England, the S.W. Highlands, and N.E. coast of 

 Scotland. — B. M. : North of Douglas, Isle of Man. liarcaldiue, Argyle- 

 shire ; Portlethen, Kincardineshire.

 minate, granuloso-areolate, dark-greyish (K — ). Apothecia moderate 

 or small, rusty-brown or brownish-black, at first lecanorine, plane, 

 with thin thalline margin, at length convex, biatorine, immargiuate 

 (K-l-dark purplish) : spores ellipsoid, polari-bilocular, 0,iJl2-17mm. 

 long, 0,006-9 mm, thick. — Cromb. Grevillea, xviii. p. 45. — Ltcanora 

 ferruginea forma coyicilians Nvl. Lich. Scand. (1861) p. 143 ; Cromb.
