1. Diatrype glomeraria, Berk. ; erumpens, angulata vel confiuenti-elongata, stromatc parco pallido, 

 peritheciis ovatis, collo brevi ostioli obscuro, sporidiis octonis curvis majoribus. (Tab. CVI. Kg. 13.) 



Hab. On smooth branches of Bhipogonum parviflorum, Titiocura, Colenso. 



Pustules thickly scattered, often connected by a thin, brown stratum, angular or elongated from the confluence 

 of two or more individuals, erumpent, but closely adherent to the cuticle, black, opaque, scarcely | a line long; disc 

 minutely scabrous ; stroma pale ; perithecia crowded, resting on the matrix, ovate, subglobose, with a short neck, 

 and scarcely traceable ostiola. Asci evanescent, containing eight, linear, obtuse, curved sporidia, r ^ Tls of an inch 

 long. — Closely allied to B. verruciformis, from which it differs principally in its smaller and more free pustules, more 

 obscure ostiola, and much larger sporidia. Those of D. verruciformis are about jJ^ of an inch long. This species 

 may also be compared with S. smilacicola, Sehwein., which is, however, smoother, and has frequently a dilated, crenate, 

 barren border at the base. The authentic specimens unfortunately are without fruit, so that I cannot compare the 

 two in this respect. That species moreover is quite free, and therefore is a true Ilypoxylon. — Plate CVI. Pig. 13. 

 a. Aseus of Diatrype glomeraria, with its sporidia, magnified, b. Sporidia, magnified 250 diameters. 



* Diatrype lata, Pr. Sphseria lata, P. 



Hab. On dead sticks, Colenso. 



Gen. LXVI. SPILEBIA, Hall. 



Stroma nullum vel spurium, myceloideum. Perithecia varia, firma, verticalia, nigra vel fuliginea, ssepe 

 corticata. Asci perfecti ; sporidia ut plurimurn octona. 



This comprises all such species as are either simple or merely connected by mycelium, which does not form a 

 regular stroma in which the perithecia are immersed. The species are very numerous, occurring in all countries and 

 situations, even at some depth in salt water, or on the rejectamenta of the tide. (Name from a<f>aipa, a sphere.) 



1. Sphseria (Csespitosas) fragilis, Berk. ; peritheciis congestis fragilissimis nigro-fuscis obtusis opacis mi- 

 nimis, sporidiis hyalinis breviter subfusiformibus uniseptatis. (Tab. CVI. Pig. 7.) 



Hab. On the under side of the leaves of Eurybia furfur acea, Colenso. 



Porming little scattered clusters of brownish, opaque, obtuse, extremely brittle perithecia, insomuch that they 

 break off while still filled with the white mass of fructification. Ostiolum obsolete. Sporidia varying from xoWo~ 

 TrsTo °f an mc h in length, shortly fusiform, often broader at one end, uniseptate, hyaline. — This species has the 

 habit of S.pulicaris, but is totally different. There is not the slightest tinge of blue, as in that species. — Plate 

 CVI. Fig. 7. Sporidia of Sphmria fragilis, magnified 250 diameters. 



2. Sphseria (Csespitosse) pullulans, Berk. ; peritheciis aggregatis subglobosis astomis vel ore leviter 

 prominulo opacis, ascis subcylindricis, sporidiis oblongis utrinque attenuatis curvulis uniseptatis. 



Hab. On leaves of Leucopogon Fraseri, principally on the under surface, Mission Station, Colenso. 

 (Tab. CVI. Pig. 6.) 



Porming little specks on the leaves, consisting of a few crowded, subglobose, opaque, dark brown perithecia, 

 without any trace of blue, either altogether destitute of any distinct orifice, or with a slight papillasform prominence. 

 ■Asci subcylindrie ; sporidia composed of two opposed cones, about T y^o of an inch long. — Plate CVI. Pig. 6. 

 a. Asci of Sphmria pullulans, magnified, b. Sporidia, magnified 250 diameters. 



3. Sphseria (Csespitosse) rasa, Berk. ; conferta, peritheciis oblongis apice convexo obtuso liberis, os- 

 tiolo punctiformi, superficie opaca quasi rasa, ascis farctis, sporidiis curvulis. 



Hab. On dead decorticated Weinmannia, head of the Biver Manawatu, Colenso. 



Porming little round neat clusters. Perithecia oblong, crowded together below, free above, and convex, not 

 collapsing, pierced, with a minute orifice, opaque, as if minutely downy, but in reality rough from the projecting dis- 

 sepiments of the external cells, as if they had been shaved off. Asci cylindrical, slightly attenuated below, con-
