180 SOME NEW JERSEY FDNGI, 



Ostiola small, with a sliort compressed mouth ; sporidia lanceo- 

 late, brown, scarcely constricted in the middle, paler towards each 

 end, central cells broadest diminishing towards the poles (•04-"05 

 X -01 m.m.), fig. 2.

2318. Fhoma consozta. C. dj E. — On decorticated maple. 

 Ca^spitosa, atra. Peritheciis superficialibus globosis ; sporis 



linearibus, truncatis, nucleatis (fig. 6). 



Forming small tufts of 3-4 perithecia, which are small, black, 

 smooth, and shining. Spores linear, truncate, with a nucleus at 

 each end, and sometimes one in the centre ('014 m.m. long). 



Figures are also given on the same plate of two species of 

 Lophiostoma, found in the United States.

NEW BKITISH LICHENS. 



By THE Rev. J. M. Crombie, F.L.S. 



Since my last notice in " Grevillea," Vol. iii., pp. 190-1, the 

 following new species, recently detected in Britain, have been 

 recorded by Nylander in the '' Flora" for 1875 : — 



1. Calicium elassospozum. Nyl. — Subsimilar to C briinneolum 

 (more robust), but with smaller spores and gonidia. Thallus 

 glaucescent or glaucous-green ; gonidia conglomerated in deformed 

 Kyngonidia ; spores globulose, '0,0025 m.m. in diameter.* 



On putrid trunks of decorticated alder. Glen Lockay, Perth- 

 shire (Crombie, August, 1875). 



2. Ramalina Cuznowii. Croml. in litt. — Thallus pale-glaucous, 

 slender, fruticulose, rounded or somewhat compressed (but with 

 some of the laciniaj broader and jDlaner), sparingly branched and 

 intricate, subrigid ; apothecia pale, convex, geniculato-adnate ; 

 spores ellipsoid, straight, "0,011-15 m.m. long, '0,004-6 m.m. 

 thick. 



Thallus K X yellowish, blackish at the base ; spermogones ex- 

 ternally black, with sperraatia '0,003 m.m. long, '0,001 m.m. 

 thick. It is, perhaps, nearest to H. cuspidata, though from the 

 spermogones it would belong to the section of R. carpathica. 



On maritime rocks, near Penzance and the Lizard, Cornwall 

 (W. Curnow). 



3. Flacodium dissidens. JV^/Z.— Perhaps a subspecies of PL 

 murorum, to which it is sufficiently similar, but the lacinise are more 

 discrete and subfree. From PL elegans it differs in the vitelline 

 colour of the thallus and the planer laciniae : spores '0,009-16 m.m. 

 long, -0,005-7 m.m. thick. 



On the slate roof of houses, near Cirencester, Gloucestershire 

 (W. Joshua).
