370 BRITISH DISCOMYCETES. 



Name Vermis, a worm, fero, to bear ; from the shape 

 of the sporidia. 



Dolgelly, North Wales ! 



Doubtful Species. 

 23. Patellaria citrina (ChevaL). B. and Br. 



Cups plane ; externally pallid ; hymenium lemon- 

 coloured ; asci clavate ; sporidia filiform. 



Patellaria citrina B. and Br., " Ann. Nat. Hist.," 

 No. 583 ; Berk., " Outl./' p. 373. Ascobolus citrinus 

 -Cheval, " Flo. En. Par.," i. t. .31 ; Cooke, " Handbk," 

 2165. 



On rose-twigs lying in a running stream. April. 



Our plant answers exactly in outward appearance to 

 that of Chevallier, having a broad, flat, yellow hymenium, 

 with a pale border. The asci are clavate, and contain 

 long filiform sporidia. We suspect that these are what 

 M. Chevallier calls asci, considering the included granules 

 as sporidia, exactly as Madame Libert has done in Stictis 

 SeslericB (B. and Br.). 



Penllergare, near Swansea (Mr. M. Moggridge). 



The affinity of this species is somewhat doubtful, 

 and there being but a single cup in Mr. Berkeley's 

 herbarium, it cannot be examined without the risk of 

 destroying it. 



24. Patellaria melazantha. Fries. 



Sessile, waxy, dry, patellate ; externally approaching 

 black ; margin very entire ; hymenium yellowish. 



Peziza melazantha Fries, " Sys. Myco.," ii. p. 150. 

 Patellaria melazantha Fries, " Summa Veg. Scan.," p. 

 3(56. Peziza melanotheja Fries in Cooke's " Handbk.," 

 No. 2123 (?). 



There is some confusion in Fries's " Sys. Myco." with 

 regard to this name, the author having named two 

 different plants by it. Whether both have occurred in 

 Britain is doubtful.
