(Type in Herb. Berk., Kew, n. 4722.) 



In the fruit of Oxyria reniformis. Rare. 



The infected fruit is much larger than the normal 

 form, of a bright chestnut colour, and remains closed 

 for a long time, when crushed, the profuse powdery 

 mass of resting-spores resembles soot on the fingers. 

 Germination unknown.

Sori forming long streaks on the leaves, at first 

 covered by the epidermis, then pulverulent, brown ; 

 resting-spores globose, pale brown, covered with

 part) ; Plow. Brit. Ured. and CTstilag. p. 284 (in

(Type specimen in Herb. Berk., Kew, n. 4738.) 



On leaves of grass. Rare. 



The present species has been referred to Tilletia 

 striiformis, Magnus, by various authors, but an exa- 

 mination of the type specimen shows it to be quite 

 distinct ; it is^ however, morphologically closely allied 

 to Ustilago macrospora. The generic position is
