Tolyposporiiiin 189 



On Lepidosperma atVfustatuDi R. Br. = L. viscidum R. Br. 

 Victoria— Stawoll, Feb., 1904 (Reader). 



On comparing this species with that of T. rodivayi occurring on the same 

 genus, it is found that the densely warted spores distinguish it at once. There 

 are also fewer spores in the ball, as may readily be seen on comparing Plate 

 XLVII., Figs. 154 and 155.

Gahnia. 

 51. Tolyposporium muellerianum (Thuem.) McAlp. 



Sorosporium muellerianum Thuemen, 8vmb. Myc. Austral. II., 

 p. 5, No. 98 (1878). 



Sori in spikelets, but scarcely visible to the naked eye. 



Spore-balls black to dark-brown, sub-rotund to oblong or ir- 

 regular, consisting of numerous firmly united spores, 40-50 fj diam., 

 or 50-70 i-i long, occasionally 80-90 /<. 



Spores brown, pellucid, smooth, variable in shape, ellipsoid to 

 polygonal or pear-shaped, and then sometimes slightly prolonged 

 at the point.

Lepidosperma. 

 52. Tolyposporium rodwayi McAlp. 



Sori enclosed in spikelets, not visible to naked eye, and forming a black 

 granular spore-mass. 



Spore-balls black, opaque, variable in size and shape, generally 

 spherical to oblong or elongated oblong, 30-60 /t diam. or 50-100 /( 

 long, consisting of numerous very firmly agglutinated spores. 



Spores olivaceous to brown, smooth, ellipsoid to broadly oblong, 

 occasionally with beak-like projecting, blunt processes on inner side, 

 or wedge-shaped, and adhering together by dark folds of their 

 membrane, 15-21 x 9-12 /(. 

 On Lepidosperma laterale R. Br. 



Tasmania — Longley, Dec, 1891 (Rodway). 

 It is only by strong meclianical pressure that the spores can be separated 

 and then only partially.
