69a. Lecanora Lilliei Lillie in Scott. Bot. Rev. i. p. 151 
(1912).—Thallus crustaceous, tartareous, cracked-areolate, white, 
yellow within (K—,CaCl—). Apothecia minute, black, rounded- 
difform or elongate, immersed in the areole; hypothecium 
colourless; paraphyses gelatinous-concrete, the epithecium 
olivaceous ; asci narrowly clavate; spores 4-6 in the ascus, 
ellipsoid, 13-15 p long, 5-6 » thick; hymenial gelatine deep 
blue with iodine.—Aspicilia Lilliei B. de Lesd. in Bull. Soc. 
Bot. liii. p. 515 (1906). 
Considered by de Lesdain as very similar to Lecanora calcarea, 
but differing in the yellow colour internally and in the smaller spores.

crowdedly corrugate-tuberculose or rugose ; beneath paler grey, 
subsmooth, on a short dark-brown stalk, 10-15 mm. high, 
almost the whole lower surface densely covered with pale-grey

Specimen not seen. 
Recently this plant has been published by Zahlbruckner (Ann. 
K. K. Nat. Hofm. xxvi. p. 170 (1912)) as a variety of G. rugifera Hue 
(Lich. Exot. p. 117 (1892)), a species placed under the section with 
gyrose discs, but Nylander notes that the irregularities are due to 
aggregation of apothecia (Syn. Lich. ii. p. 14 (1885)). 
Recorded by D. Lillie from Ben-na-bad, Caithness.
