45. LOBARINA Nyl. Flora 1877,:p. 233.—Thallus broadly 
lobed, scrobiculose; beneath partly tomentose, gibbous, ecyphellate ; 
gonidial layer consisting of gonimia. Apothecia lecanoroid, with 
3-septate spores. Spermogones as in the preceding genus. 
Formerly included under Stictina, but separated because the thallus is 
scrobiculose above, and destitute of cyphelle beneath. It consists of a 
single species common with us, as it is in most parts of Northern 
Europe. 
1. L. scrobiculata Nyl. Flora 1877, p. 233.—Thallus dilated, 
rigid, subopaque or opaque, more or less reticulately scrobiculosc, 
usually sprinkled with whitish or c#sio-white soredia, broadly 
lobed, glaucous-yellowish ; beneath gibboso-unequal, tomentose, pale- 
brown, the gibbi naked, white; lobes rounded, undulate and more 
or less crenate at the margins. Apothecia small, scattered, red or 
brownish-red, the margin thick, entire, inflexed; spores fusiform, 
3-7-septate, colourless, 0,050-80 mm. long, 0,006-7 mm. thick.—.

A well-marked species, not likely to be confounded with any other in 
the tribe. In young plants the thallus is orbicular, less scrobiculose and 
sorediate. The lobes are occasionally more or less white-sorediate 
at the margins. The naked gibbi of the underside of the thallus are 
due to the faveole of the upper surface; and the rhizine which 
constitute the tomentum are brown, pale, or greyish. In this country it 
is rather rare in a fertile condition. More frequently the apothecia 
appear in an abortive state, constituting the host of Céeldium stic- 
tarum, Tul.

common in most parts of Great Britain; plentiful in the W. Highlands,
