This has been hitherto, by external aspect, confused with C. 

 macilenta (K + ), but is separated by different reaction (K — ), 

 and is only a var. oi Floi'keana analogous as pleurota is to comu' 

 copioides. For various remarks connected with it, see under C. 

 macilenta, antek. 



The following remarks are from Dr. Nylander's annotations 

 on the types of Cenomyce of Delise, in his herbarium at the 

 Jardin des Plantes, Paris, which he has liberally communicated 

 (in litt.) to me: — C. digitata var. mucronata, Del. hb., has K — , 

 and C. albicans, Del., has K — , and therefore are referable to 

 hadllaris. The C. bacillaris, Del., and his varieties styracella, 

 macrocarpa, densiflora, paleata, coronata, according to the speci- 

 mens in herb. Delise, have K— , and belong to C. Flbrkeana 

 ^bacillaris. 



Var. ostreata, Nyl. (Syn. i. p. 225) = Nyl. L. P. 108. 



Of this Dr. Nylander writes (in litt.), " Ob podetia Cladonite 

 bacillaris immixta squaniis parum evolutis Lecidece ostreatce ste- 

 riHs, olim credidi Lichenem in L. P. 108 datum varietatem 

 sistere Cladonia illius squamis recedentibus. Quod corrigendum 

 est, et varietas nomine ' ostreata ' deleuda.'' 



45. C. spharulifera, Tayl. = Spruce, Amaz. 31. K — . 



46. C. cetrarioides, Schwein. = Spruce, Amaz. 35,39. K— .
