376 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 



Scarcely visible to the naked eye^ globose, flesh-coloured, 

 smooth ; asci generally attenuated upwards, often curved ; spo- 

 ridia hyaline, with two to four nuclei, and consequently either 

 uniseptate or ultimately triseptate, •0006--0005G inch long. 



897. N. yraminicola, n. s. Peritheciis ovatis sparsis demum 

 collapsis rubris; sporidiis fusiforraibus uniseptatis. 



On Aira C(2spitosa. Batheaston, Jan. 1850, C. E. B. 



Scattered over the dead leaves, ovate, red, at length collapsed ; 

 sporidia fusiform, •0007-*0008 inch long. 



Closely resembling N. Peziza ; but the sporidia in that spe- 

 cies arc broadly elliptic, 'OOOG inch long. It is possible that 

 the nuclei in the sporidia of N. yraminicola are indications of 

 two more septa.

Var. viridis. Peritheciis siccis atro-viridibus, madidis prasiis 

 ovatis pilis sparsis hyalinis obsitis; sporidiis ellipticis. 



On the under side of box leaves. Batheaston, C. E. B. 



When dry, presenting nearly black specks, when moistened, 

 green; perithccia beset with scattered hyaline hairs; sporidia 

 elliptic, -0007 inch long, hyaline. 



Our plant resembles that of Montague so closely, except in 

 colour, that we do not like, without further opportunity of study- 

 ing it, to keep it distinct. Both are probably the same thing 

 with kphariafuha, Fr. Elench. 



Chcetostroma Buxi, Cord., is appai'cntly a state of the same 

 species. See Debat's curious memoir in 'Ann. des Sci. Nat.' 

 vol. ix. 1858, where the transition from Psiionia Buxi into a 

 Nedria is all but demonstrated. 



899. Dothidea tetraspora, n. s. Stromate pulvinato ; cellulis 

 immersis 1. subpromincntibus ; ascis cylindricis tetrasporis ; spo- 

 ridiis uniseriatis uniseptatis obovatis medio constrictis. 



On dead twigs of Daplme Laureola and Ulex, Mossburnford, 

 A. Jerdon, Esq., Feb. 1859. 



Stroma pulvinate, black, either quite even or studded with the 

 projecting cells; asci cylindrical, containing four sporidia ar- 

 ranged in a single row ; sporidia 'OOl-OOlS inch long, obovate, 

 uniseptate, yellow-brown, the lower articulation generally shorter 

 and narrower. Very rarely there is a third septum.
