 numerous apothecia.

On trees; rather rare. E. B. Supplt. t. 2597, f. 1. 



Near Ashurst Wood, Penshurst. 



This lichen closely resembles V. Taylori in appearance, but is 

 easily distinguished by its 7-septate spores, those of V. Taylori 

 being 1 -septate. 



From the small number of species above recorded of the 

 Lecideinei, Graphidiei, and Pyrenocarpei, it will be seen that there is 

 yet much to be done in these groups in Kent, and many species 

 might probably be added by careful observers. I may here remark 

 that I shall be glad to examine and record any specimens of 

 Kentish lichens sent for that purpose to my address, 30, Arthur 

 Eoad, Holloway. 



Insert under Sphoerophoron coralloides, Pers. (p. 210). Muscus 

 coralloides Tunhridyensishracteolis nigerrimis, Petiv., Muse. Cent, 

 ii. et iii. 1698, no. 437. 

 Found by Mr. Petiver on the rocks near Tunbridge. 

 This locality is given because the plant still grows, although I 

 have not observed it in fruit, on rocks on the Kentish side of 

 Tunbridge Wells.
