FmgL] FLORA OF NEW ZEALAND. 193 



ia 1 line or more in diameter, irregular, brown ; coat thick. Spores ovoid, scarcely ever attenuated, -j-}^- 

 of an inch long. This species is allied to C. microspermus, but has larger spores, and the habit of 0. vemicosus. 



Gen. XXXVII. CBUCIBULTJM, Tulasne. 



Peridium primum globosuin, tandem crucibuliforme, et epipkragmate piano, concolore, furfuraceo, 

 cyathi marginibus extremis continuo clausum ; textura fibroso-spongiosa, homogenea, nee e stratis parallele 

 oppositis distinctis constans, ore admodum nudo absque ulla corona limbari. Sporangia subtus sphserula 

 tegumenti fibrosa contigua prsedita. 



There are but two species of this genus, one of which occurs all over Europe, the north of Africa, and in 

 North America. (Name from crucihulum, a crucible.) 



1. Crucibulum vnlgare, Tul. I. c.p. 90. 



Hab. On twigs, etc., Ahuriri, Buamahanga, Colenso, Raoul ; Bay of Islands, /. D. II. 



Another fine Crucibulum, which appears to be the same with a species from the Himalayas, to which I have 

 given the name of 0. Emodense, was found on wood at Nelson (Mr. D. Monro). Unfortunately there are no spo- 

 rangia, so that I cannot speak positively about the species. 



Gen. XXXVIII. LEPTOSTRQMA, Fries. 



Perithecmm tenue, planum, demum. circumscissum ; sporis minimis, sporophoris suffultis. 



Obscure Fungi, consisting of depressed, irregular, or orbicular peritheeia, which easily fall off, leaving behind 

 the thin lower half, which is perfectly adnate with the matrix. Exotic species have been little studied ; some are 

 probably merely the second form of certain Spharia. (Name from Xctttov, a mite, and orptofw,, a stratum.) 



1. Leptostroma litigiosum, Desm. JExs. no. 1327. — Var. exasperatum. 

 Hab. On dead stems of ferns. 



Some individuals exactly resemble the plant of Desmazieres, while others are strongly granulated. In the 

 absence of fruit, it is best to consider the two as merely forms of the same species. 



Gen. XXXIX. PHOMA, Fries. 



Peritheeia immersa, minuta, subglobosa. Spores minutissirnse, subelliptica;, ut plurimum utrinque nu- 

 cleate^ sporophoris brevibus sunultse. 



Black specks of extremely simple structure. Many of the species are undoubtedly merely spermogonia. (Name 

 from <£o>yu.a, a pustule.) 



1. Phoma fallax, Berk. ; peritheciis snbglobosis fuscis supra translucidis, sporis oblongis subcymbi- 

 formibus hyalinis. 



Hab. On the fruit of Ripogonum parviflorum, Bay of Islands, J. B. H. 



Consisting of scattered or crowded minute dots, black when dry, brown when moist, thin and transparent above, 

 so as to appear like tiny discs. Spores oblong, subcymbiform, hyaline, ^-^ of an inch long. 



2. Phoma acmella, Berk. ; epidermide brunneola tecta, peritheciis depressis, sporis variis oblongis 

 utrinque leviter attenuatis. (Tab. CVI. Pig. 10.) 



Hab. On the same leaf with Spharia acetabulum, of which perhaps it is only a form. 



On both sides of the leaf, but especially on the upper ; indicated by little brownish spots, which are darker in 



he centre, or, when the cuticle is cracked over the peritheeia, lighter. Peritheeia depressed. Spores about V- of
