lobed, sorobiculoso ; bouoatb p a rtly tomentose, gibbous, eoyphellate ;
gonidial layer consisting of gonimia. xlpothcoia Icoauoroid, with
3 -septate spores. Spermogones as in tho preceding genus.
Formerly included under Stictina, but separated because the thallus is
serobiculose above, and destitute of cyphellæ beneath. I t consists of a
single species common with us, as it is in most parts of Northern
Europe.

A well-marked species, not likely to be confounded with any other in
the tribe. In young plants tbe thallus is orbicular, less serobiculose and
sorediate. The lobes are occasioually more or less wliite-sorediate,
at the margins. The naked gibbi of ‘the underside of the thallus are
due to the faveolæ of the upper surface ; and the rhizinæ which
constitute the tomentum are brown, pale, or greyish. In tliis country it
is rather rare in a fertile condition. Alore frequently the apothecia
appear in an abortive state, constituting the host of C'elidium stic-
tarum, Tub
Hab. On the trunks of old trees and on moist shady rooks, chiefly near
streams and lakes in maritime and upland districts.—Histr. General and

Thallus either cyphellate or eoyphellate boiioath ; gonidial layer
consisting of gonidia or gonidimia. Apothecia lecanoroid or p a rmeleine.
Separated from Stictinei by tbe nature of the gonidial layer. In otlier
respects the two are very similar, several of tlieir species being clistiu-
guishahle from each other only by the gonidia.

serobiculose ; beneath p a rtly rliiziuoso-tomontoso (with rhizohyphæ),
gibberoso-unequal, eoyphellate; gonidial layer consisting of true
gomdia,^ b right-green or y olio wish-green. Apothecia leoanoroid,

_ This has the same relation to Sticta th at Loharina has to Stictina and
IS similarly distinguished by the serobiculose upper, and the ecyphàlate
lower surlace of the thallus. I t includes a very few species.
