 Sevenoaks ; Hotbfield ; Wye ; Tunbridge Wells. 



The form most common in tbe county is of a dark grey colour, 

 by wbicb tbe patcbes are visible at some distance. On Toy's Hill 

 a curious form occurs in a damp wood, in wbicb tbe apotbecia 

 appear to bave become cepbaloid and abortive. 



P. VELATA [Turn,) Isidium coccodes (^ phijinatodes (Jenner Fl. Tunbr.) 

 On trees, es^Decially in damp localities ; comparatively common 

 in Kent, altbougb considered rare in many counties. Tbe 

 fi-uctification ratber rare. E. B. 2062. 

 Tunbridge Wells Common ; Jenner Fl. Tunhr. Tbornden 

 Wood ; Hytbe ; Hurst W^ood, near Tunbridge Wells ; Ide 

 Hill; and Toy's Hill, near Sevenoaks. Igbtbam. In 

 fructification on a tree near tbe Hungersball Eocks, 

 sparingly, and abundantly on an old beecb tree in Cbal- 

 locks Wood, near Wye. 

 In tbe barren state tbis species is easily detected by immediately 

 turning a brigbt red (almost scarlet) witb solution of cbloride of

 colour wben toucbed first witb solution of potasb and tben witb 

 solution of cbloride of lime. Tbe colour is not always immediately
