NEW BRITISH LICHENS. 181 



4. Iiccanoira jejuna. Nyl. — Thallus greyish or leaden-greyish, 

 thin, subsmooth, at length rimose ; hypothallus black, everywhere 

 visible; apothecia testaceo-reddish, small, slightly prominent, the 

 thalline margin thin, at length excluded ; spores 8 na3, colourless, 

 ellipsoid, 1-septate, •0,018-23 m.m. long, -0,007-9 m.m. thick; 

 paraphyses slender, epithecium yellow ; hymenial gelatine bluish, 

 and then violet with iodine. 



In the general appearance of the thallus, this species approaches 

 to Lecanora gibhosa or L. Icevata, in that of the apothecia to 

 Lecidea coarctata ; but in reality it belongs to the section of 

 Lecanora disparata. This is shown by the spermogones, which 

 have shortly-articulated sterigmata, with the spermatia ellipsoideo- 

 oblong, '0,002 m.m long, scarcely "0,001 m.m. thick. 



On siliceous rocks. Boulay Bay, Jersey (Larbalestier). 



5. Opegxapha axeniseda. JVi/l. — Thallus scarcely any or obsolete ; 

 apothecia black, linear, subgyrosely conglomerated in pulvinate, 

 deformed acervuli ; epithecium narrow ; spores colourless, fusi- 

 form, 3-5 septate, -0,014-16 m.m. long, "0,004 m.m. thick ; hypo- 

 thecium black ; hymenial gelatine, reddish wine-coloured, with 

 iodine ; spermogones congested in small black glomeruli ; sper- 

 matia straight, "0,0035-"0,0045 m.m, long, "0,0010 m.m. thick. 



On sandy soil. St. John's, Jersey (Larbalestier).

Bi/ Prof. Fries. 



Cel. C.GiLLETii opus Champignons qui croissent en France, cujns 

 partem priorem (p. 1-272) nuper recepimus, vastum evadere videtur 

 et plure coutinet species, quam pollicetur. Nam prjeter species ab 

 Auctore in Norm mdia tectus et plene descriptus, recepta^ sunt 

 fere omnes in Epicr. 1 descriptee. Editio vero altera Epicriseos 

 Auctori ignota videtur, quare nonnull^e species I.e. descript^e sub 

 novis nominibus in Gilletii opere inserts. Sic e depictis. 

 Amanita murina = Am. urceolata, Ep. 2, 

 Lepiota Brebissoni = Agar, serenus, Ep. 2. 



,, Movieri = A. sistratus, Ep. 1, 

 Triclioloma saevum ex habitu, var. Agarico personati, ' 



Trichol. imbricatwn melius refert, Agaricum furvum. 

 Clitocybe insignis, optime sistit, Agaricum Veneris. 

 Lepista Alexandri = Paxillus Alexandri, Ep. 2. 

 Lactarius torminosus ad Agaricum Cilicioidem propius accedit. 

 Prima pars continet tertiam partem Agaricinorum et 50 tabulas, 

 in quibus plures nobiles species bene pictse. Lepiota mastoidea 

 vix mea. Lepiotce granulosus formse graciliores, quam vidi.
