Though appearing as if de.scendiiig from C. squamosa, yet preserving as
it constantly does its own type, this may rightly be regarded as a distinct
species. At first sight, as observed by Nylander (Syn. p. 210), it loolcs
almost as if it were a foliolose species of Bceomyees, or, when tbe apothecia
are se.ssile, as if it were a squamulose Lecidea with reddish apothecia.
When more developed, it forms erect imbricate tufts of moderate size,
and when less developed and with the squamules more scattered (terri-
cole) it is rather widely expanded. The podetia, whicli arise from the
upper surface of the laciniæ, are naked or occasionally subverrucose, and
often so short th at the apothecia and tbe spermogones are apparently
sessile on the leaflets.

From the preceding species, to states of which it bears considerable
resemblance, this is distinguished by tbe microphylline thallus, tbe sub-
leprose margins of tbe leaflets, and tbe granulate or squamulose podetia.
Alore especially, however, and at once, it may with certainty be recognized
by the reaction with K. In suitable habitats it spreads somewhat
extensively, and is generally fertile. The apothecia are small, but are
seldom seen simple.

In various respects Ibis resembles C. pyxidata of the preceding section,
but is at once distinguisbed by tbe scarlet apotbecia, wliich, however, in
old age (and also in herbaria) frequently become denigrate. AA’hen
sterile, tbe colour of the podetia, the less dilated margins of the scyphi,
and the chemical reactions prevent it from being confounded with pyxidata.
I t is a somewhat variable species with respect to the podetia,
which are either regular and simple (stcmmatina Ach.), or proliferous
from the margins {extensa xAch.), occasionally becoming in old plants
custate. The basal squamules are sometimes small or rarely subeva-
ni'scent. AA’hen fertile the apotbecia are occasionally expanded and
nearly cover the whole interior of the scyqilii.
