ELOBA 01 NEW ZEALAND. 



[Licit enes. 



having their margins completely beset with a crowded mass of minute rufous apothecia, which become darker in age. 

 When moistened, the plant becomes dull green, pale and pellucid. I am unwilling to separate this from C. fascicu- 

 lar, Borr.!, but other specimens so named {e.g. Sober. ! n. 415) are evidently something very different. The pre- 

 sent plant certainly does not belong to 0. nigrescent.

Hab. Northern Island, on the ground, barren, Colenso. 



The determination of an indifferent barren specimen cannot be regarded as certain in so difficult a genus as this 

 is ; but there is no reason to suppose it to be anything different from the common European species. 



Besides the above, I have seen some specimens of Collemata from New Zealand, which I am unable to deter- 

 mine with satisfaction. 



Teibb IT. MYRIANGIACEjE. 

 Gen. XXXI. MIRIANGIUM, Berk, et Mont. 



Thallus orbiculatus, tuberculatus, aut insequabilis, ambitu plicato-striatus, gelatinosus, atro-fuscus, 

 intus pallescens. Apothecia imperfecta tuberculiformia, immarginata, perfecta vero scutelliformia a thallo 

 marginata, primo clausa dein aperta thalamium includentia crassum concolor fuscum.

1. Myriangium inconspicuum, Bab.; thalli pulvinulis minutis subpapillatis glabris (fere 1 lin. latis) 

 subglobosis, apotheciorum disco subrufo inconspicao subimmarginato, sporidiis minutissimis oblongis uni- 

 septatis. (Tab. CXXVIII. B.) 



Hab. Northern Island; on dead leaves, apparently of Phormium tenax, Colenso. 



A very much smaller species than M. Buricei, Berk. ! et Mont. !, and in Mr. Berkeley's opinion quite distinct 

 from it. He finds the sporidia to be -^Vo of an inolx lon S in the present P lant > oblon g> constricted a little towards 

 the middle, and uniseptate. The disc of the apothecia is not without difficulty to be distinguished from the thallus ; 

 that which may be considered such is very obscurely margined by the thallus, and of a rufous tinge, and is possibly 

 imperfect. Both M. Burial and M. Curtisii, Berk. ! et Mont. !, have a much more depressed as well as larger 

 thallus. I could have wished to have seen more and better specimens of this plant, but was loth to omit mention 

 of it altogether. The most perfectly developed species of the genus (M. Curtisii) occurs in North America, another 

 (M. Buriai) in Algiers, and the same, as it seems, occurs in France and the Channel Islands (Salwey !) ; a third is 



found in Australia. Plate CXXVIII. B. Fig. 1, plant, natural size; 2, apothecia; 3, vertical section of ditto ;

Tribe III. CffiNOGONIEJE. 

 Gen. XXXII. CGENOGONIUM, Ehrenlerg.

Hab. -Northern and Middle Islands ; fertile, Colenso, U Urville. 



Found in the West Indies (Montagne !), Guiana (Montague !), Cumana and Peru (Humboldt), Brazil (Ehren- 

 berg), the Ladrone Islands (Gaudichaud), Van Diemen's Land (Gunn !), and New Holland (Sieber!). I have 

 also a barren fragment from the Mauritius.
