CoLENSo. — On new Species of Fungi. 311 



Of the small terrestrial Algse sent in that parcel only two 

 species were determined, and both of genera hitherto unknown 

 in New Zealand, viz. : — 



1. Phormidium, or Chthonoblastes, sp. 



A peculiar-looking plant, found overrunning gregarious and 

 short mosses growing in patches, in rather long lines which are 

 nearly straight, both brown and black, having a ribbon-like 

 appearance ; scarcely visible to the naked eye when dry, but 

 very plain when wet, especially after much rain. 



2. Dritosiphon muscicola, Kutz. 



A pretty little blue hairy erect moss-like plant, found in 

 retired holes and clefts in the cliffy banks, among grass and 

 herbage ; Scinde Island, Napier.

Total number of species new to our N.Z. Flora 179 



Two striking facts will here immediately arrest our atten- 

 tion, (the same, too, as were quite as noticeable on the former 

 occasion above mentioned,) viz. : — 



1. The large number of Fungi here in New Zealand that are 

 identical as to both genera and species with those of 

 England and other western countries, a few of them 

 being almost cosmopolite. 



2. The small number of truly indigenous species novse. 



And that those Fungi that are at present undiscovered will 

 still continue to be found bearing pretty nearly the same ratio 

 I have little doubt. 



Another fact worthy of notice is the large number of genera 

 not hitherto known to inhabit New Zealand. From the pre- 

 ceding list it appears there are no less than 68 genera new to 

 this country, many of them at present possessing but a single 

 species ; yet, as several of those genera contain a large number 

 of species in other lands, it is but reasonable to suppose that 

 the number of each will be largely augmented here.
