superficial resemblance to the Caliciei, yet, unless it constitutes a separate
and intermediate tribe, it ma}', from its general habit, be referred as an
aberrant genus to the Boeomycetei.

This plant has a somewhat fungoid aspect, but analysis shows it to be
a liclieu. The thallus is normally orbicular ; but is at length more or
less widely spreading. Its varnished appearance and the numerous
bæomycetüid apotbecia easily distiuguish it. The frequent spermogones
are brownisli-black, the spermatia about 0,001 mm. long, scarcely
0,0005 mm. thick.

In this form, differing from the type only in the smaller .apothecia, the
stipes is occasionally so short th at the apothecia are almost ses.sile on
the thallus.

p . 17 5 ,— Thallus crustaceous, granuloso-pulverulent or squamose.
Apotheoia sessile or stipitate, opaque, biatorine, th e stipes formed
of the constricted extended hypothecium and of longitudinal filamentose
elements ; hypothecium pale ; spores usually 8næ (in
elongato-cylindrical thecæ), ellipsoid or fusiform, simple or septate,
colourless ; paraphyses slender, not very discrete ; hymenial gelatine
eith e r no t tinged, or pale bluish w ith iodine. Spermogones tu b ercular,
with jointed sterigm ata and stra ig h t, cylindrical spermatia.
Although the apothecia are more or lets stipitate, this genus, were it
not for the spermogones, might be included amongst the Lecideei. No
doubt the spermogones equally differ from those of this serie.s, so that

the general habit, looking towards the Cladonias, must determine its
nlace The differences in the tballus and apothecia m some species are
not sufficient to separate them generically, though they place them m
dillerent sections of the same genus.
