340 THE CKYPTOGAMIC FLORA OF KENT. 



L. PYRACEA (Ach.) Var. ulmicola (DC.) 



On old elms in i)arks, &c., especially where moisture lias formed 



a track down the trunk ; frequent. E. B. 1426. 

 Wrotham ; Hothfield ; Eynsford ; LuUingstone Park, near 

 Shoreham. 



L. soPHODEs (Ach.) Var. exiqua. 

 On old oaks, &c. E. B. 1791. 

 Chelsfield ; ChaUocks Wood ; ChHstone Park. 

 Known from L. atra by its 1- septate spores. 



L. HiEMATOMMA, FJirll. 



On trees ; very rare. E. B. 223. 



On old trees in Penshiu'st Park, with young apothecia. 

 Known from Fertusaria velata SiudLecidea imlycarpa in the barren 

 state by turning yellow with solution of potash and with chloride 

 of lime, and from L. rubra by its immersed, deformed apothecia. 

 I have also observed L. hmmatomma in fruit on old trees near 

 Shiere, in Sm-rey. 



The Lecidea hcBmatoinma recorded in Forster El. Tunbr. as 

 occurring at Rusthall Common is probably an error, although 

 given as " Tunbridge " in Leighton L. El. on Forster's authority. 

 I have never seen this lichen on Eusthall Common, and Forster 

 remarks with regard to it, " Lichen coccineus of Dickson, but not 

 the hamatomma of E. Bot." Lecidea cuarctata var. glohiUosa is, 

 however, very frequent on the rocks at Eusthall Common, and 

 may have been mistaken for it. 



Urceolaria scruposa (L.) 



On old walls, mosses, rocks, &c. ; common. E. B. 266. 



On Eusthall Common ; Forster Fl. Tiinhr. On Tunbridge 



Wells Common ; Jenner Fl. Tunhr. Wall near Hayes 



Common ; Penshurst, on sandstone, Eusthall Common ; 



on trees near Hungershall Eocks, Ightham. 



Known from Lecanora (jibhosa by the thallus tiu-ning pale red 



with solution of chloride of lime, and by the murali-locular spores. 



Pertusaria multipunctata {Turn.) Yariolaria multijpunctata, E.B. 



On trees, especially where the bark is decayed underneath ; not 

 common in Kent. E.B. 2061. 



Thornden Wood, near Canterbury ; Toy's Hill. 



Often closely resembling some forms of P. velata, but easily 

 distinguished by not turning bright red with solution of chloride 

 of lime as P. velata does. Mudd makes P. midtipunctata a variety 

 of P. (jlobulifera, from which it is quite distinct, the latter giving 

 no reaction at aU with caustic x^otash, while P. multipunctata turns 

 yellow and then brown. 



P. DEALBATA [Ach.) Isidiwi) coralUnum (Forster Fl. Tunbr.) 

 On subalpine rocks ; rare in Kent. E. B. 1541. 

 Eusthall Common, near the Cold Bath ; Forster Fl. Tunbr. 

 I liave not observed this lichen on Eusthall Common.
