Differing from L. gibbosa in the appearance of thallus and 
apothecia, which look as if washed smooth, and in the internal 
structure. The paraphyses are more sparsely septate and have not 
so constantly the bead-like appearance upwards. Hue (Nouv. Arch. 
Mus. Paris, 1910, p. 34) has, however, described them as moniliform 
and greenish-black above. 
Spermogones have spermatia 9-15 p» long (or longer), *5 » thick. 
Hab. On schistose rocks in mountainous regions.—Distr. Local

81. L. Bockii Th. Fr. in Bot. Not. p. 105 (1867).—Thallus 
effuse, plane, cracked-areolate or of minute scattered warts, 
sometimes with sorediate spots, olive-brown or brownish-grey, on 
a thin black hypothallus (K(CaCl) + reddish). Apothecia small, 
immersed or sessile, the disc black, irregular in outline, the 
thalline margin entire ; paraphyses slender, septate, the epithe- 
cium brown ; spores broadly ellipsoid, 16-21 p long, 8-11 p thick; 
hymenial gelatine blue, the asci wine-red, with iodine.-—Cromb. 
in Journ. Bot. xx. p. 274 (1882) & Monogr. i. p. 464. Parmelia 
Bockii Rodig ex Fr. Syst. Orb. Veg. i. p. 285 (1825). 
Evidently a very rare lichen. The apothecia are minute, semi- 
immersed and often with a dot or fold on the disc. The British 
specimens are poorly developed; the asci have a very thick tip and 
the spores are smaller than the sizes given above (Th. Fr. Lich. Seand. 
p- 170); they measure frequently about 12 » in length. 
Crombie (l. c.) quotes as a synonym Lecanora sophodopsis Nyl. 
(Flora lix. p. 233 (1876) & op. cit. p. 204 (1879) ), in the diagnosis of 
which the spore sizes are given as 17-25 » long, 11-15 pw thick. 
Hab. On a schistose wall in an upland district.—B. M. Near 
Staveley, Kendal, Westmoreland (the only British record). 
82. L. complanatoides A. L.Sm.—Thallus rather thin, effuse, 
cracked-areolate, the areole small (about +3 mm. in diameter), 
smooth, sometimes subsquamulose, with a black hypothallus 
brownish-yellow or -cinereous (K —, CaCl —). Apothecia small, 
immersed then plane, the margin scarcely visible, the dise dark- 
brown ; hypothecium colourless ; paraphyses slender, coherent, 
flexuose, septate, the cells about 8 p long, rarely branched below, 
clavate and often shortly branched abov e, the tips dark-brown, 
becoming green with potash ; asci clavate up to 68 yp long, 
10-12 pw “wide, not thickened at the tips; spores 8 in the ascus, 
ellipsoid, 10-14 » long, 4-6 » thick; hymenial gelatine blue 
then tawny with iodine.
