FLORA OF NEW ZEALAND.

Hab. Northern Island, on bark, Colenso. 



Very nearly allied to P. anrantiaca. Our specimen is named by Dr. Montague, who has given an ample de- 

 scription, and we have added a figure. — Plate CXXIX. A. Fig. 1, plant, natural size; 2, portion of thallus and 

 apothecium ; 3, vertical section of apothecium ; 4, portion of ditto ; 5 and 6, sporidia : — all highly magnified.

 I have not seen a New Zealand specimen.

Hab. Northern Island, on bark, overrunning Hepaiicm, Colenso. 



Some incomplete specimens collected by Mr. Colenso appear to belong to this polymorphous West Indian and 

 South American species. In addition to the synonyms given by Dr. Montagne, we should be inclined to add, with 

 Eschweiler, Lecanora versicolor, Fee, Essai, t. 28. f. 4, and P. chrysocarpa, Meyer, in Spreng. Syst. Veg. p. 329. cur. 

 post., judging from the description. 



45. Parmelia clirysosticta, Tayl.! {sub Lecan.) ; " crasta tenui albida nigrolimitata (?), gemmis granu- 

 latis confertis, apotheciis confertis concaviusculis disco flavo-lutescenti pruinoso margine gemmis crenulato."

" Crust several inches wide ; the investing crust is studded with large granular buds, which sometimes bear on 

 their tops minute orange spots, the rudiments of apothecia. The disc consists of a coarse yellow pruina, covering 

 a deep tawny lamina. The shields are much larger than those of L. ferruginea, Hook., and have a conspicuous 

 thallodal border." Tayl. I. c. Sir W. J. Hooker has written against a specimen " allied to P. tarlarea ;" and cer- 

 tainly this pretty plant appears far more near to that species than to P. ferruginea, and it seems to differ in nothing 

 but in its smaller and much brighter apothecia : the hypothallus is not clearly visible, but it rather appears to be 

 pale, as in that species. I endeavoured, to no purpose, to discover asci and sporidia ; a section of the disc showed 

 numerous elongated paler bodies imbedded in it, but these seemed to contain no vestige of sporidia; under the 

 microscope the surface of the disc appears broken up into scales not unlike the thallus of P. hypnorum, Fries. Mon- 

 tagne describes the asci as very large, enclosing a single multicellulose sporidium. Some of the smaller specimens 

 much resemble P. cerina, but they show the same (inorbosely ?) pruinose disc as the larger specimens. 



Obs. Mr. Colenso has collected two or three specimens of a Patellaria unknown to me, which may possibly 

 be P. atrocinerea, Fries. His description and the figure in E. Bot. (t. 2096) agree pretty well; but in the absence 

 of an authentic specimen I am compelled to pass his plant over without further notice. 



§ 6. Ueoeolahia, Fries. 



46. Parmelia scruposa, Fries, Lich. Furop. p. 190. Urceolaria scruposa, Acli. et Atcett. 

 Hab. Northern Island, Colenso. 



A very widely dispersed species, occurring over Europe and North America, from the Arctic Circle southward, 

 and I have it from Malta and Madeira. It is found likewise in the Canary Islands and at the Cape of Good 

 Hope. 



47. Parmelia verrucosa, Fries, Lich. Fur op. p. 186 {cum syn.). Behcet. 1 Fxs. n. 120. 

 Hab. Northern Island, accompanying P. rubiginosa, var. araneosa, Bab., Colenso. 



Mere fragments occur in the collection, but they manifestly belong to this species. It is widely diffused over
