The figure in " English Botany Supplement," above referred to, is 

 not identical with that which appears in Bry Brit. ; but in this, the 

 older, figure — just as in Bry, Brit. — the filiform processes are repre- 

 sented fully as long as the external teeth. I have no doubt that this 

 English Botany figure is the one upon which Mr. Wilson bestowed so 

 much pains on the 29th March, 1833. The italics in the following 

 passage, from the description which accompanies the figure in English 

 Botany, make the Bryologia Britannica description all the more 

 inexplicable : — 



" Outer peristome of sixteen pale yellow acuminated teeth, which 

 in dry and mature specimens are strongly incurved so as to be con- 

 cealed within the capsule. Inner peristome a membrane divided 

 almost to the base into sixteen very narrow filiform erect processes, as 

 long as the outer peristome, without intermediate cilia." There are 

 appended to this description the well-known initials, "■ W. W." 



Perhaps Mr. West will pardon me if I say that the Tunbridge 

 locality is not new. The credit of that discovery belongs to the late 

 Mr. Borrer. In a letter to Mr. Wilson, dated July 15th, 1844, 

 referring to various mosses, he wrote : — " Ortliodontium gracile I have 

 found on sand-rocks near Tunbridge Wells."

BUCKINGHAMSHIKE LICHENS. 



By Wm. West. 



Me. E. M. Holmes, F.L.S., who is well known as a devoted and 

 assiduous cryptogamist, recently sent me a parcel of lichens which he 

 had collected during a ramble in Buckinghamshire ; the majority of 

 them were already named by him 

 species : — 



The following is a list of the 



Leptogium lacerum, Ach., a rare 



species 

 L. subtile, Schrad. 

 L. firmum, Nyl. (Collema plicatile, 



Leight) * 

 Caliciuni hyperellum, Ach. 

 C. curtum, Borr. 



Tracliylia stigonella, Fr., an un- 

 common species 



Evernia prunastri, L. 



Ramalina evernioides, JSTyl. , a '^re- 



ticulata-rugosa " specimen 

 E,. poUinaria, Ach. 

 Peltigera polydactyla, Hfiba. 

 Parmelia physodes, L. 

 P. saxatilis, in fruit (which is rare) 



on a tree 

 P. perlata, L. 



* IMr. Holmes i)oints out that this rather rare species is a true Leptogium^ having 

 a cellular surface.
