On rabbit-dung. Autumn. 



Cups j^q, rarely T ^- , of an inch broad, formed of a 

 single layer of subcubical cells, with a single row of 

 sharp, pointed hairs, often roughened on their sides about 

 ■J to I of the whole height ; disc plane, granulate ; asci 

 narrower than usual ; sporidia normally 32, oblongo-fusi- 

 form. To be distinguished from A. cunicularis by the 

 shorter and tapering rough cilia, as well as by the thinness 

 and transparency of the walls (Renny). 



Name — After M.M. Crouan fre'res. 



Hereford (Mr. James Renny).

Ryparobius argenteus — B. and Br. in "Ann. Nat. 

 Hist.," No. 1394; " Grevillea," ii. 163. Ascozonus cuni- 

 cularius — Renny, "Trans. Woolhope Club," 1873, p. 129, 

 t. i, f. 1-4; and "Jour. Bot," 1874, p. 355, t. 155, f. 1-4. 



On rabbit-dung, for the most part attached to fila- 

 ments of Mucor. 



Cups lOO^u across, scarcely visible to the naked eye ; 

 asci opening with a little lid, which splits vertically. 

 Comes near to R. felinus (Boud.), but has soft hairs, and 

 is of a pure white (B. and Br.). But for the colourless 

 sporidia, this, as well as Nos. 6 and 7, should belong to 

 Saccobolus, on account of the " sporidiferous cysts." 



Name — Argentum, silver, having a silvery appear- 

 ance. 



Near Hereford (Mr. Renny). 



5. Ryparobius Leveilleanus. (Renny.)
