1874, p. 16 ; Cromb. Jo u rn . Bot. 1882, p. 274, is according to
Wainio and Arnold a sterile and less developed sta te of this plant.
A very distinct species which at first sight seems near L. oculata, but,
as riglitly conjectured by Nylander I. c., from sterile specimens, belonging
to tbis section. The papillæ are scattered or here and there crowded,
becoming at times entirely leprose. In the very few British specimens
neither apothecia nor spermogones, the latter as yet unknown, are
present.

A rather singular plant of this section both as to thallus and apothecia.
The subglobose verrucæ are usually discrete, and when rubbed are more
or less yellow-greenish at the apices. The apothecia are at length as if
gyroso-plicate, whence Fries (Lich. Eur. p. 151) observed that, if normal,
the plant would belong to a distinct genus. Its true systematic place,
however, is shown by Nylander, Flora, 1876, p. 233 (cfr. Flora, 1879,
p. 204), s. n. Lecanora sophodopsis, under which synonym the first complete
diagnosis is given. The British specimens iu which neither the
thallus nor apothecia are well developed belong to a form pauperata
Nyl. in litt. The spermogones are here and there visible, with spermatia
straight, 0,0045 mm. long, 0,0005 mm. thick.
