NEW BlUTISH LICHENS. 



23 



On schistose boulders on Morrone, Braemar, and Hill of Ardo, 

 near Aberdeen (Crombie). The spermogones are not visible in 

 any of the specimens gathered, and but for scanty presence of 

 gonidia in the perithecium this species might readily have been re- 

 ferred to the Leciclei. 



6. Iiecanoza austeza. i\yZ.— Tliallus cervine, or cervine-badious, 

 unequal, rimose, thin ; apothecia badious-brown, somewhat large, 

 the thalline margin badious, somewhat shining, flexuose, often sub- 

 crenate"and proliferous; spores 8 nge, ellipsoid, about 009 m.m. 

 long, about 0-007 m.m. thick ; paraphyses moderate, articulated ; 

 hymenial gelatine scarcely tinged, but the thecse bluish, with 

 iodine. 



On weathered quartzose stones in gravelly places near the summit 

 of Ben Cruachan, Argyleshire (Crombie). Very rare, and 

 gathered only sparingly on a single boulder. 



7. Iiecidea lubens. 7\'yZ.— Thallus effuse, granulose, greyish glau- 

 cous; apothecia small, numerous, crowded, at length convex, pale 

 flesh-coloured or livid-brownish ; spores very variable, 5-9 septate, 

 0-028-50 m.m. long, 0-007-11 m.m. thick ; hymenial gelatine 

 deep bluish with iodine. 



On the bark of trees, near the roots, at Shere in Surrey (Crom- 

 bie). Allied to L. sabuletorum^ var. amoena, Ohl., but diflering in 

 the character of the spores, 



8. Iiecidea scopulicola. Ayl. — Th alius greyish-green, verriicoso- 

 unequal, thinnish, effuse ; apothecia brownish flesh-coloured, at first 

 obtusely margined, when old convex ; spores 8 nx, acicular, thinly 

 or obsoletely 3-5-septate, 0-032-44 m.m., 0-002 m.m. thick; para- 

 physes slender, epithecium colourless, hypothecium colourless (but 

 tawny-brown in the subhymenial stratum) ; hymenial gelatine 

 bluish, and then tawny wine-coloured with iodine. 



On maritime rocks, near Penzance in Cornwall (Curnow). 



9. Lecidea phylliscocarpa. Nyl. — Thallus brown, very thin or 

 evanescent ; apothecia black, phylliscoid (umbilicately affixed), 

 rosulato-corapound, rotundato-difformed, large, above with the mar- 

 gins thin, subradiately and irregularly disposed, slightly costate, 

 and at the circumference sub-crenato-effigurate, within blackish, 

 the hymenial stratum whitish ; spores 8 nse, ellipsoid or oblong, 

 simple, 0-009-11 m.m. long, 0-0035-45 m.m. thick; epithecium 

 bluish- blackish, paraphyses thickish, bluish-black at the clavate 

 apices, hypothecium sordidly dark ; hymenial gelatine intensely 

 bluish with iodine. 



On quartzose stones, amongst detritus on the summit of Morrone, 

 Braemar (Crombie). A very singular species, readily recognised 

 from the phylliscoid appearance of the apothecia. 



10. Lecidea dealbatula. yA'yZ.— Thallus white, thin, rimose or 

 subareolate, unequal; apothecia black, small, prominent, margined, 

 umbonate or at length subgyrose in the centre, concolorous within ;
