Tolyposporium. 187 



Sori ill spikes, and destroyiiio; them, cylindrical, 2-5 cm. long, at first 

 covered by the yellow epidermis, then ruptured. 



Spore-balls very black, rounded, oblong or polyhedral, variable 

 in size, 40-150 /i diam. 



Spores sub-globose or ellipsoid, cinnamon-brown, with thickish 

 (1 ^t) very finely punctulate epispore, 9-14 x 8-12 \i. 



On Anthistiria ciliata L. f. — Kangaroo grass. 

 New South Wales— 1892 (Cobb). 

 Victoria — Kiewa Valley, Nov., 1902 (Robinson). 

 Queensland — Walsh River (Bailey)^. 



Germination. — The spore germinates in water, giving rise to an elongated, 

 septate promycelium, which bears lateral and terminal fusiform conidia, 

 5-10 /-t long. The detached conidia bud in a yeast-like manner.

Thecaphom glohuligera Berk, and Br. Trans. Linn. Soc, 2nd 

 Ser., Vol. II., Pt. 1, p. 407 (1878) 



Sori in ovaries, subglobose, 1-2 mm. diam., covered by yellowish-green 

 smooth membrane, which ruptures and exposes the black masses 

 of spores. 



Spore-balls opaque, firm, composed ot numerous spores, 50-200 f.i 

 diam. or even more. 



Spores olivaceous to brownish, subglobose to angular, rough, 

 and tubercular but not echinulate, generally polygonal, with obtuse 

 angles by which they are united to each other, average 9-11 //. 



On Leersia hexandra Swartz — Rice grass. 

 Queensland — Brisbane River (Bailey). 



This grass is common near water-courses and is often attacked by this 

 smut. 



The swollen ovary retains its outer coat while the contents are completely 

 replaced by the spores. 



The projecting processes of the spores and how they are united to each 

 oth°r is well shown in Plate XLV., and justifies the change in the genus 

 made by Ricker.
