The thalhis, wliich is bright green when moist, becoming in old herbaria 

 specimens reddish-brown, varies somewhat in texture according to habitat, 

 and is sometimes more or less wliite-;i:niinose (form pruinosa Fr. Lich. 

 Eur. p. 49). The saccato-impressed apothecia, which in old plants are 

 occasionally somewhat large, render this species easily recognized, though 

 without examination of the spores it might be confounded with <S'. hispora. 



Hub. On the ground and decayed mosses, in crevices of rocks, rarely ou 

 the mortar of old walls, in moist shady places, in upland and siibalpine 

 districts. — Distr. General, but not common, chiefly in W. and N. Eng- 

 land, X. Wales, and on the (u-ampians, Scotland; scarce in S.AV. and Js. 

 Ireland. — B. M. : Cheddar Cliffs, Somersetshire ; near Buxton, Derby-

3. S. spongiosa Xyl. ex Carroll, Journ. Bot. 18G5, p. 288. — 

 Thallus suborbicular, s(juamulose, dark-green when moist, grevish- 

 brown when dry ; squamules small, suberect, minutely inciso-lobed 

 and crenate, at length becoming granulato-crustose. Apothecia 

 deeply urceolate, becoming nearly jilane, dark chestnut-coloured or 

 almost blackish, bordered externally by a thiunish, granulate, 

 thalloid margin : spores 4n?e, ellipsoid, brownish, 0,030-0,050 mm. 

 long, 0,018-0,023 mm. thick.— Cromb. Lich. Brit. p. 30.— C'oZZma

A singular-looking plant, sometimes regarded as a variety of S. saccata, 

 with which perhaps it is connected by intermediate states, traces of the 

 normal thallus being occasionally seen around the apothecia. It difl'ers, 

 however, from it in the squamulose thallus, and more slightly in the mar- 

 gined apothecia and the thinner spores. The large and sometimes numerous 

 apothecia become nearly plane when old. 



JInb. On the ground among rocks, and on turf walls, in upland districts- 

 — Disfr. Rather local and scarce, chiefly in N. England, among the
