8. Peziza chrysotricha, Berk. ; cupula sessili primum globosa demum subhemisphEerica aurea floccis 

 innatis intricatis vestita subpulverulenta, sporidiis brevibus cymbiformibus. (Tab. CV. Kg. 7.) 



Hab. On twigs on the shores of Waikare Lake, Colenso. 



About a line across. Cups bright golden-yellow, at first globose, then subhemispherieal, sometimes with a 

 slight membranous edge, thickly clothed with short, matted hairs, somewhat pulverulent. Hymenium closed when 

 dry, seated on a stratum of large, but unequally-sized cells. Asci cylindrical, rather large; sporidia cymbiform, 

 slightly attenuated at either end, T i-g- of an inch long.— A remarkably beautiful species.— Plate CV. Fig. 7. 

 Peziza chrysotricha, natural size, a, hairs ; b, external cells ; c, ascus and paraphyses : — magnified, d. Sporidia,

* Peziza monticecola, Berk. ; atra, expansa, margine angusto, ascis clavatis amplis, sporidiis subcymbse- 

 formibus endoehromate partito. 



Hab. On decaying Monlia fontanel. Ahuriri, Eastern Coast, Colenso. 



Minute, black, soon expanded, with a narrow margin, sometimes flexuose. Asci clavate, large ; sporidia sub- 

 cymbiform ; endochrome bipartite ; paraphyses linear, much longer than the asci. — Allied to P. atrata, but appa- 

 rently distinct from all its forms. 



Gen. LVII. PATELLABIA, Fries. 



Receptaculum marginatum, patelheforme, semper apertum. Eymeniwn, lceve, persistens, sed ex apici- 

 bus ascorum aere adustis pulverulentum. 



The more persistent cups and the pulverulent hymenium, like that of many Lichens, the tips of whose asci are 

 often rough, with little amorphous granules, distinguish this genus from Peziza. I do not find the asci connate, 

 nor are paraphyses wanting. Most of the species are found exclusively in the temperate zones, but P. nigro-cinna- 

 barina, Schwein., which occurs in the warmer parts of the United States and Surinam, occurs also in New Zealand. 

 (Name from patella, a saucer.) 



1. Patellaria nigro-cinnabarina, Schwein.! Syn. no. 1959. 

 Hab. On dead branches, Colenso. 



Exactly the North American species, which is remarkable for its vermilion-coloured hymenium. The sporidia 

 resemble those of Hysterium elevatum, P. 



2. Patellaria atrata, Pr. Syst. v. 2. p. 160. 

 Hab. On dead bark, Colenso. 



Specimens from different parts of the world vary a little in the shape and length of the spores, and the more 

 or less flexuous cups, but all agree in essential characters. The New Zealand specimens are seated on a white crust, 

 winch is clearly extraneous. 



Gen. L VIII. CENANGIUM, Fries. 



Receptaculum subcoriaceum. Hymenium laeve, persistens. Cupula clausa, sero aperta. 



Eesembling Peziza in outward form, but of a firmer, tougher texture, and peculiar habit. (Name from kej/os, 

 empty, and ayyeiov, a receptacle.) 



* Cenangium Colensoi, Berk. ; sparsum, primitus oblongum, demum orbicuiari-expansum, fuscum, 

 hymenio pallido subcarneo, sporidiis minutis elliptico-subcymbiformibus. 



Hab. On dead leaves, apparently of P/wrmium, Colenso. 



Scattered, at first covered with the cuticle, at length expanded, externally brown ; disc pale, faintly tinged with 

 pmk. Asci oblong. Sporidia elliptic, subcymbiform, hyaline, 4 J Q - of an inch long.
