dering the, inckicled granules as sporidia, exactly as Madame Li- 

 bert has done in Stictis Seslerice. 



We have another pezizseform fungus from Mr. Moggridge also 

 found in water, with no definite margin, of a grayish tint, spark- 

 ling from the prominent asci, which contain elliptic sporidia. 

 This curious plant belongs apparently to the genus Psilopezia. 



584. Tympanis saligna, Tode, Fung. Meek. tab. 4. fig. 37. On 

 twigs of privet, Lucknam, Wilts. 



A very curious circumstance has occurred in this species, which 

 we presume from Tode^s figure to be identical with his plant. In 

 the same hymenium the fruit of a Diplodia and that of a Tym- 

 panis were present. This is somewhat analogous to the occur- 

 rence of more than one species or genus in the same spot of 

 Uredo, and Fries informs us that he has observed a similar fact 

 in Hendersonia SyringtB. 



585. Cenangium RibiSj'Fi'. Sc. Suec. no. 131. On dead branches 

 of currant-trees, Thame, Dr. Ayres. 



586. Phacidium Rubi, Fr. Scler. Suec. no. 56. On dead bram- 

 ble stems, Twycross, Wanvickshire, Rev. A. Bloxam. 



The asci, paraphyses and sporidia are just the same as in P. 

 coronatum. 



587. Hysterium curvatum, Fr. H. elongatum var. /3., Fr. El. ii. 

 p. 138. On dead rose and bramble stems, Shrewsbury, Rev. W. 

 A. Leightou. 



Certainly distinct from H. elongatum in its longer, more deli- 

 cate spores, in addition to other more obvious characters.

 stems of herbaceous plants, Bristol, H. 0. Stephens.

OOMYCES, n. g. 



Perithecia erecta in sacculo polito sursum libero recepta ; os- 

 tiola punctiformia. Asci lineares ; sporidia filiformia longissima. 

 Fungus Iseticolor graminicola insectorum ova referens. 



590. Oomyces carneo-alhus = Bph. cameo-alba, Libert, Fasc. 3. 

 no. 241. On leaves of Aira ctespitosa, Spye Park, Wilts. 



Scattered, shining, pale flesh-coloured, conical, truncate above, 

 and marked with the ostiola, f line high. Perithecia 3-7, ver- 

 tical, closely packed in the common tougb receptacle. Asci elon- 

 gated, cylindrical. Sporidia filiform, extremely long, flexuous. 



A very pretty production, which can scarcely be forced into 

 the genus Bphceria. It resembles greatly an Aa-ospei-mum, though 

 differing completely in structure, and like that genus might 

 easily be mistaken for the egg of some insect, such as Crioce^is. 

 The structure is not visible until a section be made, except so far
