376 FUNGI. [Ureda. 



ceous seed retaining its triquetrous form ; epidermis cracked, white and 

 very delicate. Sporidia large, subglobose, furnished with a pellucid 

 border, their surface granulated. 



8. U. olivdcea, Dec. [olive-green Uredo) ; infesting the en- 

 larged receptacle, epidermis soon bursting, sporidia olive-green 

 powdery minute mixed with fibres which belong to the receptacle.

On Carex riparia. Fotheringhay, Norths. Rev, M. J. Berkeley. 

 — Springing from the receptacle as in U. segetum, which is much in- 

 creased in size. Sporidia accompanied by vertical filaments, which on 

 dissection are seen to spring from the hard base and are I believe the 

 fibro-vascular cords which run from the rachis. The utriculi are 

 altogether external to the mass. I have not seen sufficient specimens 

 to ascertain whether the germen as well as receptacle is attacked, but I 

 am inclined to think that such is not the case. 



9. U. caricina, Schleich, (Sedge Uredo) ; spots red, sori oval 

 minute scattered surrounded by the ruptured epidermis, sporidia 

 subglobose reddish then brown. Dec. Fl. Fr. 6. p. 83. — U, 

 ohlongata^ Grev. So. Crypt. Fl. t. 12. Fl. Ed. p. 437. (iti part).

On Carex pendula and Pseudo-Cyperus. Edinburgh, Z);-. Greville. 

 — The specimens figured by Dr. Greville are on C. pendula, and are 

 seated on a yellow spot. \t\ is matter of doubt therefore whether they 

 may not belong to U. Rubigo^ those gathered by him on C. Pseudo- 

 Cyperus being the true U. caricina. The plant on Luzula is quite 

 different and is the true U. oblongata. 



10. U. oblongata, Grev. (oblong -seeded Uredo) ; spots oblong 

 often confluent yellow-brown, sori elliptic amphigenous, epi- 

 dermis closed, sporidia brown obtuse at either extremity.

On Luzulce. Edinburgh, Dr. Greville. Berwick, Dr. Johnston. 

 Bagley Wood, Oxf., Baxter. — Very different from the last in its 

 sporidia. 



\\. U. Scilldruniy Grev. (Hare-bell Uredo) ; spots oblong or 

 subrotund crowded into patches, epidermis bursting longitudi- 

 nally, sporidia rubiginous obovate shortly pedunculate. Grev. I

On the Hare-bell, Dr. Greville The sporidia are rubiginous in the 



dried specimens before me, from which the above character is drawn up. 



12. U. Alliorum, Dec. (Garlic Uredo); spots obliterated,

 globose, yellow or whitish. Dec. Fl. Fr. 6. p. 82. Desm. !
