Communicated hy The Rev. J. M. Crombie, F.L.S. 
The following new species of Lichens discovered in this country 
have since rny last communication in Grevillea, Vol. x, pp. 22-24, 
been described by Nylander in the “ Flora.” 
1. Ephebeia IKEaztindalei, Cromb., 2Vyl. in Flora, 1883, p. 104. 
Subsimilar to E. hispidula (Ach.), but differing in the thallus, 
being scarcely spinulose, and in the receptacle of the apothecia 
above being smaragdine (or sub-bluish in thin section). Spores 
oblongo-ellipsoid, simple, 0*009-0’014 mm. long, 0*004-0'06 mm. 
thick. 
On moist rocks. Mardale, Westmoreland (Martindale). Pro- 
bably a subspecies of E. hispidula. 
2. Lecanora {Placodmm) miniatula, Nyl. in Flora, 1883, p. 98. 
Subsimilar to L. lobulata (Smmrf.), with the thallus subminiate, 
planer, and the spores smaller, 0*007-l’010 mm. long, 0’004-0-005 
mm. thick. 
On quartzose rocks. Morrone, Braemar (Crombie). Probably 
only a variety or subspecies of L. tegularis (Ehrh.). 
3. Lecanora circinatula, JSfyl. in Flora, 1883, p. 100. 
Thallus dark-grey or brownish-grey, adpressed, diffract, radioso- 
divided at the circumference, the radii plane ; apothecia dark- 
brown, innate, plane, the thalline margin thin, entire ; spores 8 nse, 
simple, ellipsoid, about 0*007 mm. long, 0*005 mm. thick, para- 
physes thickish, articulated ; hymenial gelatine at first bluish, and 
then tawny wine-red with iodine. 
On siliceous stones, in maritime districts. Near Beachy Head, 
Sussex (Crombie). Allied to L. circinata, but smaller, and with 
smaller spores. 
4. Lecanora decincta, Nyl, in Flora, 1882, p. 452. 
Thallus umbrine, smooth, thin, rimulose, greyish at the circum- 
ference ; apothecia black, opaque, plane, the thalline margin not 
prominent, internally subincolorous or brownish ; spores 8 nae, 
ellipsoid, simple, 0*010-14 mm. long, 0 006-8 mm. thick, para-
