formation of a distinct genus. The specimens in my copy of 

 Sderomyc. Suecice do not belong to this species but to Peziza 

 fusarioides. I have examined repeatedly specimens from va- 

 rious localities and find all to agree with the accompanying 



figure.

91. Sclerotium negledum, Berk. Brit. Fung. Fasc. 3. n. 165. 

 On dead leaves of various trees, as poplar, sycamore, oak, &c. 

 Winter. Very common. More or less oblong, subadnate, at 

 first covered with the cuticle, pallid ; at length naked and 

 dark-brown. Nearly allied to S. inclusum, Schm. and Kz. 

 n. 137 5 °ut besides being almost adnate and seated in general 

 upon the main nerves, it is far less wrinkled when dry, and 

 pale when young. 



*92. Sphceria ophioglossoides, Ehr. Beautiful specimens of 

 this very rare species occurred at Kingfs Cliffe, September 

 and October, 1837. The observations upon the curious 

 structure of the parts of fructification in this and the allied 

 species given in Eng. Fl. have been fully confirmed by the 

 examination of the recent plant. The asci are very long, ac- 

 companied by extremely slender paraphyses,and contain about 

 six rows of minute oblong sporidia, which remain attached to 

 each other after they have escaped, presenting when the asci 

 burst the appearance of the threads of a Schizonema.

 Fung. Fasc. 3. n. 168. For observations upon this most in- 

 teresting plant I refer to the Magazine of Zoology and Botany, 

 vol. ii. p. 223.

 1. c. p. 284. In the month of April I found some old matting 

 covered with this fungus, in its infant state, in the church at 

 Apethorpe. Having kept it in a cellar till the present month 

 (October), it has perfected its perithecia, and given me an op- 

 portunity of ascertaining that it is a true Sphceria, with perfect 

 asci. I had before suspected such to be the case from the
