inclusa ; peritheciis astoniis globosis hyalinis coniluentibus ; 

 ascis linearibus; sporidiis octonis globosis. 



Leigb Wood, Bristol, Sept. 1859, C. E. Broome. 



Parasitic in the flesh of Tuber puberulum, occupying the place 

 of the ascj ; perithecia globose, hyaline, confluent ; asci short, 

 linear; sporidia 8, globose, •00015-*0002 in diameter.

 tissue of the truffle ; b. asci and sj)oridia. 



^Diatrype stipata, Curr. The fruit figured in this Journal as 

 that of Valsa hypodermia belongs to this species. That of V. 

 hypodermia is fusiform and hyaline. Mr. Currey now believes 

 that his plant is identical with Sphceria dissepta, Fr. 



971. Nectria Albertini,B. & B. ; SpJiceria rosella,A.8i, S.t.9.f.3. 

 Peritheciis gregariis ovatis acutis papillatis roseis subiculo tomen- 

 toso rosco insidentibus ; sporidiis medio tumidis fusiformibus 

 uniseriatis. 



On the ground, on sticks, leaves, &c. Leigh Wood, Bi'istol, 

 C. E. Broome. 



This diff"ers from the plant gathered by Bloxam and Car- 

 michael in the larger fusiform, not short oblong, uniseptate 

 sporidia. In N. Albertini they are "0014 inch long, in N. rosella 

 only '0005. We have a plant from Madeira which agrees in the 

 fusiform sporidia, but in which the perithecia are sunk as in 

 Hypocrea. In Rabenhorst's specimen of Sphaeria rosella, besides 

 the asci and oval spores, there are what we believe to be stylo- 

 spores, oblong and triseptate, •001-"0012 inch long.

 N. rosella. 



'^Nectria Peziza, Fr. Summ. p. 388. Sphceria aurea, Grev. t.47, 

 usually referred to N. aurantia, Fr., is scarcely difi'ei'cnt from N. 

 Peziza. Spharia aurantia /3. fulgens appears to be the same. 



*Melogramma oligosporwn (No. 895) = Spharia macrospora, 

 Desm. 



972. Spharia (Villosse) scaiigena, n. sp. Peritheciis liberis 

 ovatis subtiliter hispidis, pilis brevibus rigidis ; ostiolo papillse- 

 formi, apice truncato ; sporidiis globosis. 



On horse-dung, King's Cliffe, with S. stercoraria, Sow. Spring. 



Perithecia free, ovate, rough, with very short rigid hairs; 

 ostiolum papillseform, truncate ; asci cylindrical ; sporidia uni- 

 seriate, broadly elliptic, subglobose, at flrst surrounded with 

 gelatine, "0008 inch long, flattened, so that a lateral view gives 

 a narrow elliptic outline. 



The sporidia in S. stercoraria are '00012 inch long; the peii- 

 thccia are immersed in a decided stroma even when solitary.
