328 DECADES OF rUNGI. 



An extremely pretty little plant, but wliicli will probably, with seve- 

 ral neiglibouring forms, growing on living leaves in the tropics, be 

 ultimately reduced under one common head, as they differ only in the 

 mode in which the stroma is broken up, and slightly in the admeasure- 

 ment of the sporidia. I have not found perfect fruit in the present 

 species, 



487. S. (Obvallatse) Nepalensis, n. s. ; pustulis depressis; peritheciis 

 decumbentibus cireinantibus ; collis longis, ostiolis obsoletis; sporidiis 

 oblongis curvatis- 



Hab. On dead twigs of birch, Tangma valley. East Nepal, 9000 

 feet. November 29. (Dr. Hooker,) 



Pustules not a line broad, flattened; disc even, Perithecia circi- 

 nating, decumbent, seated in the cortical substance, which is heightened 

 in colour so as to be almost orange when seen by transmitted light, 

 within which, in the centre of the pustule, the matrix is pale, approach- 

 ing to white; necks long; ostiola obsolete. Asci linear; sporidia bi- 

 seriate, linear-oblong, curved, an^nn of an inch lonsj. 



I have very insufScient specimens of this species ; but as it is clearly 

 undescribed, and the species of the genus in the surrounding countries 

 are but little known, and, as it should seem, rare, I am unwilling to 

 omit it. 



* Corynelia uheriformiSy Pr, 



Has. On Fodocarpus. Khasia Mountains. (Dr. Hooker.) 

 Perfectly agreeing with specimens from the Cape, the species of Fodo- 

 carpus on which it grows being also identical with the Cape species. 



* Meliola^ sp. 



Two species occur, the one on Ilicine<B^ the other on Myrtacet^^ at 

 Amure, in Khasia, but neither with perfect fruit. 



488. Polyporm (Mesopus) Campbelli, n. s, ; lignicolor, subcarnosus; 

 stipite central!, cum pUeo turbinato undulato confluentc ; poris minimis 

 brevibus decun-entibus. — Pr. Nov. Symb. p. 33. 



Hab. On the ground, into which it penetrates. Poonah. (Assistant 

 Surgeon J. D. Campbell, Esq.) 



Wood -coloured, at least when dry. Pileus subcarnose, 3 inches 

 across, plane, but undulated, turbinate, confluent with the stem, which 

 is either short and central, or slightly excentric, irregular, and elon- 

 gated. Pores dccurrent, minute, short ; orifice oblique, elongated. 



This highly curious species, of which I have merely two sections.
