1 88 Tolyfosforium. 



J uncus. 

 48. Tolyposporium juncophilum McAlp. 



Sori in the stems, forming dense powdery masses of spores which burst 

 through and dust it over with a black powder. 



Spore-balls opaque, composed of numerous, firmly united spores, 

 subglobose to oblong or irregular. 



Spores olive-brown, subglobose to ellipsoid or polygonal, epi- 

 spore unequally thickened, smooth.

 In T. junci (Schroet.) Woron. Schroeter says that the peripheral cells are 

 shortly echinulate on the outer surface, but in this species they are perfectly 

 smooth. In addition to this the spore-balls are generally more or less sub- 

 globose, while in T. junci they are elongated and contain fewer spores in 

 the ball.

McAlpine, Proc. Linn. Soc. N.S.W., XXIX., p. 127 (1904). 

 Sacc. Syll. XVIL, p. 491 (1905). 



Sori in ovaries, black, powdery, but completely enclosed in the small 

 fruits, surrounded by the enveloping bracts. 



Spore-balls composed of numerous spores, firmly united into 

 irregular masses, subglobose to oblong, 80-120 i^i long. 



Spores olivaceous in mass, globose to subglobose, ellipsoid or 

 polygonal, finely warted, 12-14 f.i diam. or 12-16 x 10-11 /*.

50. Tolyposporium lepidospermae McAlp. 



Lepidosperma. 



Sori enclosed in spikelets and not visible to naked eye, except from the 

 spore-balls, being scattered over the inflorescence, forming a black 

 granular mass. 



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

 to oblong, or irregular, 50-60 /< long, consisting of numerous spores 

 firmly agglutinated together. 



Spores brown to chestnut-brown, subglobose to ellipsoid or poly- 

 gonal, strongly warted all over, variable in size, 15-17 n long.
