Ms. Turner's Rescript iotts of 
of botany in greater confusion than ever. In this number is L. aci- 
cularis, with which, from its former name of fulVus, it might be 
presumed that L. chrysocephalus had a strong affinity: nor is there 
any thing in the specific character that satisfactorily destroys such 
an idea ; and yet, considered as to their substance, nature, tuber- 
cles, or crust, they can by no means be arranged even in the same 
genus. 
Lichen fuscelius. 
2. L. crusta crassa laevi areolata grisca intus nigra ; thalamis pla- 
nis subimmersis minutis atris. 
Tab. VIII. Fig. 2. 
Habitat in ecclesiarum muris apud Bradwell et Gorlestone hi 
Suffolcia. 
Crusta absque norma effusa, lineam et ultra crassa, superficie 
sequalis, lsevis, rimosa, aut, ut aptius dicam, in areolas figuras 
magnitudinisque incertae diffracta ; colore extus pallide griseo, 
intus nigro. Thalami valde minuti, atri, satis copiose in crustas 
areolis nascuntur > juniores, ut in L. endocarpa et miniato im- 
mersi ; adultiores fere sessiles ; omnes ambitu subrotundi, su- 
perficie plani, nunquam, ut in Verrucariis reliquis, pertusi, 
marginis expertes. Crusta aqua madefacta colorem non mutat, 
sin digito fricetur fit viridis, speciemque pristinam nunquam 
reversuram, omnino amittit. 
This Lichen is by no means uncommon on churches about Yar- 
mouth, growing in scattered patches of irregular size and figure, 
and generally preferring loose sand stone at no great distance 
from the ground. From its dull colour, scarcely differing from that 
of the substance on which it grows, and its imperfect appearance, 
it is easily overlooked ; yet is, nevertheless, not only a distinct 
but
