Looks like a Lecidea near L. spTiceroides, but is a true Lecanora allied
to the preceding species, as shown by the distinct thalline margin in very
young apothecia (seldom present in herbaria specimens) and by tbe character
of the spermogones. I t is somewhat variable as to the thallus and
apothecia, whence the form and variety that follow. The spores are rarely
simple, or in the same apothecium obsoletely 1-septate, so that Nylander
lit supra named this state Lecidea albocarnea. The spermogones have
the spermatia arcuate, thin, 0,014-22 mm. long, scarcely 0,001 mm.
thick.

Has much the appearauce of a youug state of L. poliophcea. In the
specimens seeu the thallus occurs chiefly iu small patches, which at times
become more or less confluent. The apothecia are only sparintey present

A peculiar species, extern J l y similar to L. Ralfsii, but differing in the
character oi the thallus at the circumference, and in the colour of the
epithecium. More important anatomical differences are the smaller
spores and especially the character of the spermogones, which latter
places it m this section. In the two fragmentary specimens seen the
ap Jh e c ia are very sparmgly present. The spermogones also are rare,
with the spermatia, 0,016-20 mm. long, 0,001 mm. thick.
