FLORA Or NEW ZEALAND.

constricted about the middle, uniseptate, finely granulated. — Plate CXXIX. B. Fig. 1, plants, natural size; 2, 

 apothecia ; 3, vertical slice of ditto ; 4, asei ; 5, immature, and 6, mature sporidia : — all highly magnified. 



7. Biatora vemalis?, Fries, Lich. Europ.p. 260. 

 Hab. Northern Island, Colenso, etc. 



Fries has certainly included several plants under this name in his ' Lichenographia,' and has changed his mind 

 considerably in his Summa Veg. Scand. The sporidia differ much in the allied species, as my friend Mr. Leighton 

 has convinced me. The New Zealand specimens appear to belong to Fries's form luteola, but I could not discover 

 the sporidia in a specimen which I examined. Probably several forms or species occur in New Zealand. 



8. Biatora rosella, Fries, Lich. Ewop. p. 259. Schmr.! n. 217. 

 Hab. Northern Island, Colenso. 



9. Biatora decolor ans, Fries, Lich. Eur. p. 266. Mcug. et NeslL! n. 551. 

 Hab. Northern Island, Colenso. 



One specimen agrees with Mougeot's ; another has the thallus thicker, more lobulate, the lobes margined with 

 white, but it appears to be the same species. 



10. Biatora anomala?, Fries, Lich. Eur. p. 269. L. cyrtellus, E. Bot. t. 2155. Borr.! 

 Hab. Northern Island, Colenso. 



The range of this and the three preceding species is probably very extensive throughout the world. 



11. Biatora carneola, Fries, Lich. Eur. p. 264. L. corneus, E. Bot. t. 965. Borr.! 

 Hab. Northern Island, Colenso. 



12. Biatora ceroplasta, Bab. ; thallo crustaceo hypophlseode demum prorumpente albido ceraceo mi- 

 nute granulifero crassiuscnlo diffracto subpellucido, apotheciis subliberis appressis majusculis planiusculis 

 demum convexis rubris ceraceis nudis, junioribus subpellucidis, margine cupulari pallidiore carneo tenui 

 evanescente. 



Hab. Northern Island, Colenso. 



It is with reluctance that I describe a new species of this difficult genus from a single specimen. The whole 

 plant looks as if it were made of wax ; it may in other respects be compared with B. rosella, Fries, but the apothecia 

 are not in the least pruinose, the margin is thinner, and the colour of the disc of a deeper red, resembling that of B. 

 pachycarpa, but not quite so dark. Colour of the disc flesh-coloured within, resting on a paler line, i.e. the cupular 

 excipulum. I failed to discover asci or sporidia. 



13. Biatora cinndbarina, Fries, Lich. Eur. p. 266. (Tab. CXXIX. C.) 

 Hab. Northern Island, on branches of shrubs, Colenso. 



A beautiful little species, found also in Tasmania, North America, and Arctic Europe. Mr. Colenso's plant 

 agrees exactly with a specimen from Dovrefeld.— Plate CXXIX. C. Fig. 1, plant, natural size; 3, apothecia; 3, 

 vertical slice of ditto ; 4, more highly magnified portion of ditto; 5, sporidia : — all highly magnified. 



Obs. Besides the above, there are several New Zealand specimens of this most difficult genus, which I cannot 

 determine satisfactorily.

 Specimens indifferent, but agreeing very well with Schserer's plant, and with Fries's description of the French
