116 BRITISH DISCOMYCETES. 



On Sclerotium sulcatwn (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 l^u; 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 7J 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 a, 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 

 sclerotium ; asci cylindrical ; sporidia 8, cylindrical,
