This is at once distinguished by the colour and form of the apothecia
and by their internal structure. The tliallus, wdien sterile, often spreads
extensively, and is then more continuous and aspersed with large rosy-
white or white cephalodine granules, when it is Variolaria terricola Tayl.
iu Alack. Fl. Ilib. ii. p. 115. The apothecia are not common in this
country; but the spermogones are frequent on otherwise barren tballi.
They are somewhat large, tuberculiform, at first covered by the cortical
layer, the conceptacle blackish above, with elongate jointed sterigmata
and straight spermatia 0,005 mm. long, scarcely 0,001 mm. thick.

This plant in moist shady localities is of a beautiful green colour,
becoming yellowish when long preserved in herbaria. The apotliecia are
generally numerous, often much crowded and almost confluent, undulate
when dry, rarely substipitate, occasionally entirely lecanorine, with
depressed thalline margin. The spermogones are inclosed m the thalline
granules in colourless conceptacles ; the spermatia slender, somewhat
thickened at either apex, 0,004 mm. long, scarcely 0,001 mm. thick.
Though much difference exists as to the place of this species, it is anato-
mically and chemically a Boeomyces, as observed by Isylauder, Lapp. Ur.
