J. A. MARTINDALE : NOTES ON BRITISH LICHENS. 



9. ^Lecanora miniatula Nyl in Flora, 1883, p. 98. 



Thallus closely adnate, very minutely areolate, here and there 

 minutely squamuloso-lobate, subminiate, much resembling 

 L. obliterasce?is and states of L. lolmlata. 



Apothecia very minute, '2 to -4 mm. diameter, concolorous, at 

 first plane with a thin entire border, afterwards slightly 

 convex, the border becoming obsolete. Paraphyses stoutish, 

 articulate, sparingly branched, uppermost cells (or two 

 upper) swollen, subspherical, •oo4-*oo7 mm. diam. Spor-es 

 ellipsoid, '007 --009 mm. long, •oo4--oo5 mm. broad. 



Sperniatia . . . . ? 



On quartzose rocks, Morrone, Braemar (Crombie). 

 I have only seen one specimen, gathered by Mr. Crombie, 

 which unfortunately is without spermogones. This differs 

 from L. obliterasceiis only in the smaller size of the spores. 



10. Leeanora cirrochroa Ach., Syn., p. 181, a.d. 1814. Nyl., 



Lapp., p. 126 ; Leight., Lich. Flora, p. 161. 



Thallus closely adnate, rimoso-areolate in the centre, laciniate 

 at the circumference ; laciniae radiating, discrete, or sub- 

 discrete, linear, -125 to "3 mm. broad, convex, naked or 

 sometimes slightly suffused at the apices, which are incurved 

 and entire or sub-incised, vitelline or orange-coloured ; 

 both the central areolations and the peripheral laciniae 

 breaking out into round citrine-coloured soredia, which 

 sometimes become confluent. 



Apothecia 'minuta, plana, aurantiaca,' Fries, Lich. Scand., 

 p. 171. Spores oblong, •oi2--oi6 mm. long, •oo6--oo7 mm. 

 broad, according to Dr. Nylander. 



Sperinogonia . . . . ? 



On limestone rocks, Arnbarrow, Milnthorpe, and Levens 

 Park, Westmorland ; Brancombe Cliff, Leaton, Devonshire ; 

 Alston, Cumberland, fide Rev. W. Johnson. It occurs 

 also in Wales, I believe. 



This beautiful species is unfortunately almost barren, and 

 no fruiting specimens have yet been found in Britain. The 

 spermogonia have, I believe, never been observed. 



* * Sperinatia small (longer than in the preceding species) ; spores swollen in 

 the middle — 'lemon-shaped' (Leight.) ; ' subqviadrangular ' (Malbranche). 



11. Leeanora callopisma Ach., Lich. Univ., p. 437, a.d. 1810 ; 



Leight., Lich. Flora, 3rd ed., p. 162 (excluding varieties).
