THE CRYPTOGAJMIC FLORA OF KENT. 843 



Ightham, in fruit. 



Known by its lemon -coloured jDowclery thallus which much 

 resembles that of Coyiiocyhe furfuracea from which the character of 

 the fructification distinguishes it.

 Between Cuxton and Cobham ; sparingly. 



L. DECOLORANS, Flk. 



On the ground in hilly districts ; frequent. 

 Ightham ; St. Paul's Cray Common, Hoivse !

Westerham ; Ightham ; Dunton Green ; Beechborough. 

 [L. protnisa, Fr., which has a similar chemical reaction with 

 the last, but a wrinkled, often sorediate thallus, should be looked 

 for on the rocks at Sandgate.] 



L. ULiGiNOSA (Schrad.) 



On damp turfy earth in woods and on commons ; frequent. 



E. B. 1466. 

 Dartford Brent ; Joydens Wood ; Ightham ; Thornden Wood. 

 Known by its simple spores from L. milliaria.

 Var. glebulosa, L. glebulosa (Jenner Fl. Tunbr.) On rocks on 

 Tunbridge WeUs Common ; and near the Hood Rocks on 

 RusthaU Common. 

 Extremely variable in appearance, the apothecia often bright 

 red when wet (see L. hcematomma).

I have not observed this species in the above locality. It is 

 easily known by its mouse-coloured thallus, with black apothecia 

 having a wavy margin of the same colour as the thallus.
