FLORA OF NEW ZEALAND. 



\Fungi , 



an inch long, oblong, slightly attenuated at either end, but by no means acute.— Plate CVI. Fig. 10. Spores of 

 Phoma acmella, magnified 250 diameters. 



Gen. XL. HENDEESONIA, Berk. 



Perithecia subglobosa. Sporm sporophoris suffultse, majores pluriseptatse. 



Very pretty microscopical objects, of which doubtless a portion, like many Diplodia, are spermogonia. They 

 vary greatly in the nature of their spores ; but those species only should be admitted which have many endochromes. 

 (Named after Mr. J. Henderson, the talented gardener of Earl Fitzwilliam.) 



1. Hendersonia hjalospora, Berk. ; peritheciis punctiforrnibus nitidis subastomis, sporis linearibus bre- 

 vibus hyalinis triseptatis. (Tab. CYI. Eig. 8.) 



Hab. On bark of Olea, Tehawera, Colenso. 



Forming minute specks, scattered over the bark. Perithecia black, shining, sometimes slightly papillate, but 

 generally without any trace of an ostiolum. Spores ^Vj of an inch long, linear, obtuse at either end, hyaline, tri- 

 septate. When out of the proper focus, the articulations seem divided into two or three smaller portions. — Plate 

 CVI. Fig. 8. a. Spores of Hendersonia hjalospora, Berk., magnified 350 diameters, b. Single spore, more highly 

 magnified. 



Gen. XLI. ASCHEBSONIA, Mont. 

 Stroma carnosum ; cellurae periphericee. Sporm sporophoris oriundse, septatae I. simplices. 

 Little, fleshy, yellowish, superficial Fungi, growing on living leaves, and exactly analogous to Hypocrea. (Named 

 after F. M. Ascherson, author of some valuable treatises on Fungi.) 



* Aschersonia duplex, Berk. ; flava, rubiformis 1. simplex, cellulis majoribus mmoribusque, sporis ob- 

 longis angustis. 



Hab. On leaves of Astelia, Colenso. 



Stroma \-\ line or more broad, convex, yellow, lobed like a raspberry ; cells varying greatly in size. Spores 

 oblong, hyaline, -35V0 of an inch long. Ostiolum umbilicate, or very obscure. — Occasionally the stroma is convex, 

 and not at all lobed or compound, in which case it contains only a single large cell ; the lobes, on the contrary, often 

 contain several cells. 



Gen. XLIL PHLYCT/EXA, Bern. 



PeritJiecium spurium, convexum, ab epidermide nigrefacta formatum, poro pertusum. Nucleus gelati- 

 nosus. Sporopkora brevissimse. Sporm curvatse, elongatse vel fusiformes, dein ejectse. 



The spurious perithecium and elongated spores are the characteristics of this genus, which was proposed only 

 in 1847. (Name from <j>\vKTaiva, apustule.) 



1. Phlyctsena dissepta, Berk. ; linea nigra geographica cincta, sporis tenuissimis elongatis filiforrnibus 

 apice curvis. (Tab. CVI. Eig. 14.) 



Hab. On the same stems with PempMdmm opacum. 



Patches from a line to half an inch long, surrounded by a flexuous, irregular black line ; spots scattered, very 

 variable in appearance, sometimes colourless, sometimes with a black line or speck in the centre, and sometimes sur- 

 rounded with a black line. Sporophores filiform ; spores about -g-i^ of an inch long, filiform, strongly curved at the 

 apex. — It is possible that this may be the sporophorous form of the Pemphidium, but at present it would be prema- 

 ture to form any decided opinion on the subject. — Plate CVI. Fig. 14. Spores and sporophores of Phlyctana
