116 BRITISH DISCOMYCETES. 



On Sclerotium sulcatum (Rob. and Maz.), in the culms 

 of Carex arenaria. 



Cup 1 to 4 lines broad, stem variable in length. 



Name — After M. Durieu de Maisonneuve. 



The British specimens were grown from sclerotia 

 under artificial culture* by Mr. C. B. Plowright, of King's 

 Lynn, to whom I am indebted for specimens. No doubt 

 specimens will be found in a natural condition where 

 Carex arenaria abounds, on carefully searching. 



C. SPORIDIA OBLONGO-FUSIFORM. 



5. Hymenoscypha filipes. Phil. 



Cup thin, fragile, concave, becoming plane, at length 

 convex, glabrous, white; stem long, filiform, flexuous, 

 same colour, arising from a black, subglobose sclerotium ; 

 asci 8, oblong-fusiform, 8 x 1/*; paraphyses slenderly 

 filiform. 



Growing from a wrinkled, black, nearly globose 

 sclerotium amongst vegetable fragments in a damp 

 situation. 



Cup about 1 J lines broad ; stem 7 J lines long. This 

 is much smaller than P. Candolleana, and the sporidia 

 are altogether different. Phialea capillipes (Quelet) is 

 grey-bistre colour, and grows from & fusiform sclerotium, 

 otherwise there is a very near resemblance. 



Name — Filum, a thread, pes, a foot; from the slender 

 stem. 



Shelton Rough, near Shrewsbury ! 



D. SPORIDIA CYLINDRICAL, SLENDER. 



6. Hymenoscypha Curreyana. (Berk.) 



Cup thin, subhemispherical, then infundibuliform, or 

 plane, bright brown, glabrous ; hymenium wrinkled, 

 margin entire ; stem slender, flexuous, nearly equal, 

 smooth, or tomentose at the base, arising from a black 

 Rclerotium ; asci cylindrical ; sporidia 8, cylindrical,
