asci cylindrical clavate; sporidia •0032--0025 inch long, '00025 

 \Ande, fusiform, triseptate, hyaline, torulose, elongated at either 

 end into a slender setiform appendage. 



Allied to H. rufa, but ditferiug altogether in its fruit.

830. Hijpoxylon succenturiatum, B. & B. ; Spharia succentu- 

 ricita, Tode, Fung. Meek. fig. 109. On oak. Weybridge, Sept. 

 1856, F. Currey. 



Asci linear ; sporidia brown, uniseriate, oblong, obtuse, '0005- 

 •0006 inch long. 



831. Diatnjpe (Lignospe) undulata, Fr. Summ. p. 385. lludloe, 

 ^Vilts., Feb. 1843, C. E. B. 



What is usually considered as D. undulata is merely a form 

 of D. stigma characterized by its short sausage-shaped sporidia. 

 The specimens here referred to that species have the same ex- 

 ternal characters, but different fruit. Asci linear; sporidia uni- 

 seriate, subovate, pointed at one end, at length triseptate, "OOO^- 

 •0007 inch long.

832. D. (Lignosse) dnjophila, Currey in Linn. Trans, vol. xxii. 

 p. 269 (cum ic). On dead oak twigs. 



Asci linear. Sporidia uniseriate, dark, oblong, narrow, "OOOl— 

 •0006 inch long, sometimes binucleate. 



833. D. (Lignosse) nucleata, Currey, /. c. p. 270 (cum ic). 

 On furze. Weybridge, F. Currey, Esq. 



Sporidia linear, acuminate, constricted in the centre, 4-nu- 

 clcate, •0007-0008 inch long. 



831. D. (LignosEc) varians, Currey, /. c. (cumic.). On dead 

 twigs. Eltham, F. Currej', Esq. 



Sporidia biseriate, colourless, obtuse, constricted in the mid- 

 dle, uniseptate, ^0006 inch long, cymbiform when seen laterally ; 

 varying much in width. 



The position of this species, as Mr, Currey remarks, is doubt- 

 ful. The bark, in which the perithecia are immersed, is scarcely 

 at all changed. 



835. D. (Lignosse) denigrans, Curr. I.e. (cum ic). 

 Sporidia dark, elliptic, ^0005 inch long. 



836. D. (Lignosffi) Badhaini, Curr. /. c. (cum ic). 

 Sporidia nan-ow, subelliptic, 3-4-nucleate, appendiculatc at 



either end, -0005 --0006 inch long. 



837. D. (Lignosse) incequalis, Curr. /. c. On furze. Wey- 

 bridge, F. Ciirrey, Esq. 



Sporidia greenish, obtuse, constricted in the middle, unisep- 

 tate, ^0006 inch long.
