290 CYCLOCARPINE [LECANORA 
late (K—). Apothecia moderate in size, crowded or in pulvinate 
groups, the disc brownish, white-pruinose, the thalline margin 
prominent, entire or faintly crenulate; paraphyses stoutish, 
septate, very slightly widened at the apex; spores ellipsoid, 
11-14 p long, 5°7 p thick.—Cromb. Monogr. i. p. 406. LL. gal- 
actina subsp. urbana Nyl. in Bull. Soc. Bot. Fr. xiii. p. 368 (1866). 
Ezsice. Johns. n. 316. 
Very closely allied to L. galactina, but with a thicker thallus and 
with slight differences in the apothecia. 
Hab. On mortar of old walls near towns in lowland districts.— 
Distr. Rare in England and §. Ireland.—B. M. Lewes, Sussex; 
Folkestone, Kent; Dorking, Surrey; Berwick-on-Tweed; near Cork. 
35. L. Andrewii B. de Lesd. in Bull. Soc. Bot. Fr. lxi. p. 82 
(1914).—Thallus indistinct. Apothecia numerous, crowded, up 
to 1 mm. across, dise pallid or dull-brown, plane, margin white, 
thick, subentire or subcrenulate, persistent and flexuose 
(CaCl f+ yellow, K(CaCl) + reddish - orange) ; epithecium 
yellowish, granular ; hypothecium colourless ; paraphyses easily 
separating, slender, simple, scarcely wider above, not septate ; 
asci clavate; spores ellipsoid, 11-13 (15) pw long, 6 p thick ; 
hymenial gelatine deep blue with iodine. 
The description has been taken from de Lesdain, but examination 
of the co-type specimens shows that the apothecia are sometimes 
pruinose; the paraphyses are swollen and sometimes divided at the 
tips, thus differing slightly from those of L. galactina. Another 
peculiar feature is the reaction, which, however, occurs in a specimen 
of L. galactina var. subluta. 
Hab. On siliceous rocks partly encrusted with lime.—B. M. Braid 
Hills near Edinburgh (the only record ; collected by J. McAndrew). 
D. Varia group.—Thallus greenish-grey (reactions various or 
none). Apothecia greenish or dull greenish-brown. 
36. L. varia Ach. Lich. Univ. p. 377 (incl. f. pleorytis)—Thallus 
generally wide-spreading in a thinnish warted granular crust, 
the small warts rather unequal, crowded or sparse or almost 
absent, yellowish-green, straw-coloured or greenish-grey (K—). 
Apothecia numerous and often crowded, obscuring the thallus, 
generally about 1 mm. in diameter, becoming sometimes larger 
and irregular in form, the disc dull yellowish-brown or -green, 
sometimes darker and sometimes slightly pruinose, the thalline 
margin thin, prominent, persistent, subentire, becoming flexuose 
and angular; paraphyses slender, somewhat coherent, not dis- 
tinctly septate, the apices slightly larger or irregular, the 
epithecium of minute yellowish granules, dark-brown in thick 
section ; spores oblong-ellipsoid, 9-12 ym long, 5-7 yw thick ; 
hymenial gelatine blue with iodine.—Hook. in Sm, Engl. Fl. v.
