CLADONIA. 249 



West Coast, Herb. Hook. ; Hall ; Macoun, etc. b is found at 



the south in a delicate, well-coloured form ; North Carolina, 

 Curtis; South Carolina, Ravenel ; Alabama, Beaumont ; Florida, 



Chapman. c is also more delicate at the extreme south; 



Florida, Chapman-, and this is perhaps Michaux's v. minor, 

 found by him in Carolina. 



Ser. II. Ochroleucce. Apothecia pale flesh coloured, 

 oftener becoming reddish-brown. Podetia pale sulphur col- 

 oured, or straw-coloured. 



19. C. Botrytis (Hag.) Hoffm. ; thallus squamulose, minute, 

 erose-crenate, at length lobate ; podetia short; cylindrical; 

 slender; cartilagineous - corticate ; verruculose; pale-sulphur- 

 coloured ; dividing more or less above into sub-fastigiate branch- 

 lets which are crowned by the largish, pale, flesh-coloured at 



length brownish apothecia. Fr. L. E. p. 234. Nyl. Syn-

Rotten pine wood, British Columbia, Macoun. Growing 

 mixed with these specimens is a cornute, always simple lichen, 

 agreeing with similar (small) forms of C. flmbriata in general 

 character, as in becoming powdery above, but with the colour of 



the present, to which it is difficult not to refer it. According 



to Scha3rer (Enum. p. 192) the species is also a native of Vir- 

 ginia (Herb. Shuttleworth) and of Carolina (Herb. Moug.) but I 

 have seen nothing resembling it from the Atlantic region except 

 the small form of C. sguamosa called here f. hotryoides, which, 

 though very like the first, has the coloration and the thallus, 

 and belongs without doubt to the stock, of the other. Fries 

 took the present for an abortive cup-lichen ; a representative 

 therefore in the present series of the club-shaped group of the 

 preceding one. 



20. C. lepidota, Fr. ; thallus squamulose, minute, sub-entire, 

 but becoming elongated and much-lobed ; podetia shortish ; cyl- 

 indrical; cartilagineous-corticate ; soon verrucose; sub-simple 

 or sparingly branched; the scarcely dilated summits passing 

 into erectish, fastigiate branchlets, which, are densely at length 

 beset, as more or less also the lower portions, with rounded 

 squamules ; greenish - straw - coloured ; apothecia from pale- 

 brownish-flesh-coloured at length darker. Fries in Utt.
