Read, " Remarks on British Lichens and Fungi, principally on 

 species or varieties new to our Flora." By Churchill Babington, 

 Esq. 



The object of Mr. C. Babington in this paper is to give descrip- 

 tions of some species or varieties of Lichens and Fungi hitherto un- . 

 published in any British Flora, and also to communicate observa- 

 tions on the transit of monstrosities to their proper forms. The 

 Lichens brought into notice as not yet introduced into the British 

 Flora are, Lecanora elat'ma, Ach., from Rose Hall, Cumberland;

 Scotland ; Lecidea nitidula, Fries, also from Scotland ; Lecidea mis- 

 cella, Ach., as distinct from L. miscella, Eng. Bot. ; Biatora Kro- 

 ckicina, Hoppe, from Isles of Rum and Skye ; Biatora anomala, Fr., 

 from Yoxall Lodge ; Opegrapha signata, Ach., from Herefordshire ; 

 and Verrucaria margacea, WahL, from Charnwood Forest. Among 

 the Fungi are, Agaricus Maria, Klotsch ; A. serrulatus, Fr. ; The- 

 lophora ferruginea, Pers. ; T, lactea^ Fr. : T. Icsvis, Pers. ; Peziza 

 I,edi, Alb. and Schw. ; Stictis lichenicola, Mont. ; Sclerotium ro-

Read, " On a Gall gathered in Cuba, by W. S. MacLeay, Esq., 

 on the leaf of a plant belonging to the order Ochnacece." By the 

 Rev. M. J. Berkeley, M.A., F.L.S. 



The gall is remarkable for its very close resemblance in habit and 

 form to some epiphytous Fungi, for possessing a distinct operculum, 

 and, especially, Ibr bursting through the cuticle, which surrounds it 

 in the form of a few lacinise at the base. Mr. Berkeley pointed out 

 various forms of gulls and other productions of insects which have 

 been described as Fungi, but in none is the resemblance so striking 

 as in the present. He regretted that he was not able to throw any 

 light upon the animal by which it is caused, though he was able to 

 state positively that it is an animal production, as in most instances 

 decayed exuviae w^ere found in its cavity, and in one case a little im- 

 perfect grub, which was however unfortunately lost.
