DECADES OF FUNGI, 



a crop of spores on the opposite side. Spores yro'^io ^^ ^^ ^^^^ 

 across ; vesicular appendages large, distinct, elongated ; peduncle long, 

 hyaline, flexuous. 



This is distinguished from R. glmidulosa^ which occurs on several 

 species of TepJirosia, in South Carolina, by the long slender peduncles 

 and the distinct vesicles. It is most gratifying to have this confirma- 

 tion of a very beautiful genus. 



* Ustilago Carlo ^ Tul, 



Hab. On Cymhopogon, Khasia. (Hooker and Thomson.) 



^P^^'^^ 3 5^0 ^f ^^ ^^^ 1^ diameter, resembling those of the form 

 from New Zealand, figured by Tulasne. There is, however, the. ordi- 

 nary form on Barley from the Soane Kiver, and also one extremely 

 like Tilletia SorgU, Tul., on Saccharum, from the same locality, both 

 of which 1 regard as simple forms of the common Smut. 



466. U. bursa^ n. s. ; sporis ellipticis crassiusculis fuligineo-atris 

 minute verrucoso-echinatis. 



Hab. On the ovaries of Anthistiria arundinacea^ Sikkim. (Dr. 

 Hooker.) 



Forming a greenish bag about 2 lines long, greatly bulging exter- 

 nally, and tipped with the hard shining horny remains of the inte- 



Spores 



guments and style, frequently with a strong lateral fissure. 



elliptic, a-aVo ^^ ^"^ i^^cli l<^^g5 rather thick, olive-black. 



Differing from U, Maydis in its elliptic spores. The habit is just 

 that of the common Bunt, but I can detect no unpleasant smell. 



467. V.vitiata^ Berk.; germinis basin vittato-elongati occupans; 



sporis majoribus laevibus globosis. — ^Berk. in Gard. Chron. 1853, p. 14 8, 

 cum icone. 



Hab. On the gerraens of some Oplismenoid grass, near the summit 

 of Paras Nath, 4000 feet. (Dr. Hooker,) 



Occupying the base of the germen, which is elongated above into a 

 long strap-shaped lamina, which is tipped occasionally with the wi- 

 thered remains of the stigma. Spores subglobose, at first hyaline and 

 often pedunculate, ttoo ^^ ^^ iiich in diameter, even, at length brown. 



A very singular species, having at first the appearance of an Ergot. 

 The dark spores are however present at the base of the elongated vil- 

 lous appendage, which seem to arise from the germen. M. Tulasne 

 suggests that it may eventually prove congeneric with Tilletia Sorghi, 

 which is scarcely a good Tilletia.
