Eiityloma — Urocystis. 195 



On leaves of Eugenia. 



Queensland — Harvey's Creek (Bailey^). 

 Sections of the affected leaves show that they are sometimes confluent, 

 and that they may extend almost from the bottom to the top of leaf.

Melilotus. 

 60. Entyloma meliloti McAlp. 



Sori in leaves, forming on both surfaces minute, round, slightly raised 

 pustules, generally brown at margin, and pale or dark-coloured at 

 centre, often confluent and producing larger patches. 



Spores colourless to honey-yellow, globose to ellipsoid or some- 

 times angular by pressure, smooth, 10-12 /< diam., or 11-13 x 9-9.5//. 

 On leaves of Melilotus indica All. = M. parviflora Des. 



Victoria— Werribee, Oct., 1909 (C. French, jun.). 

 This is the first recorded species on Melilotus and even on a Leguminous 

 plant, for E. nectrioides]8])eg. is doubtfully referred to this family. In sections 

 of diseased portions of the leaf the spores are seen in great masses, and there 

 are numerous fungus filaments ramifying among them. 



(Plate LVI.) 



UROCYSTIS Kab. 



Sori usually in leaves or stems, and forming dark-coloured dusty spore 

 masses. 



Spore-balls permanent, with a special envelope of tinted sterile cells 

 enclosing one or several fertile cells. 



Spores usually dark-coloured and variable in size. 



Germination by means of a promycelium, either undivided or divided 

 into several cells, and bearing at its apex one or a whorl of elongated conidia, 

 which give rise to similar secondary conidia or to infection threads. 



This genus is often rendered conspicuous by the distortion produced in 

 the affected parts. The cortex of sterile cells usually completely envelopes 

 the fertile cells, but it sometimes only forms a partial envelope. 



Australian species, 7. 



Agropijron. 

 01. Urocystis agropyri (Preuss) Schroet. 



Schroeter, Abh. Schles., Ges., p. 7 (1870). 

 Sacc. Syll. VII., p. 516 (1888). 

 Sori forming long parallel black lines on leaves and stems, at first covered 

 by the leaden-coloured epidermis, then erumpent and pulverulent. 



Spore-balls subglobose to oblong or ellipsoid, 20-30 // long, but 

 sometimes reaching a length of 42 /;<. 



Spores deep reddish-brown, subglobose to oblong or angular, 

 1-3 not uncommon in a ball, sometimes 4 and 5, varving in 

 size, from 9-15 f.t in length ; sterile cells usually completely sur- 

 rounding fertile cells, yellowish and elongated.
