perennates in the rhizomes. The spores, according to Brefeld, 

 germinate in water after a resting period of two years ; in 

 i\vii years more they lose their capacity for germination. 



T. secalis (Cord.) l is epidemic and destructive in ovaries of 



til'l-lt/l- I'l /'I'll/I'. 



T. decipiens IVrs. (Britain). In fruits of Ayrostis mdgaris 

 and A. stolonifera. Schroeter says the plants remain stunted. 

 Brefeld states that spores germinate in water after a resting- 

 period of three years, and lose their capacity for germination 

 in the following year. 



T. lolii Auersw. frequents the ovaries of cultivated Loliutn 

 perenne, and of //. temulenlum (darnel-grass). 



T. hordei Kom. occurs in grain of Hordeutn fragile and H. mwinum in 

 Persia. 



T. separata (Kunze). In grain of Apera Spica-venti. 



T. calospora Pass. In grain of Andropogon agrestis in Italy. 



T. Rauwenhoffii Fisch. In grain of Holcus lanatus in Belgium. 



T. olida (Biess.) forms stripes on the leaves of Bracks/podium sylvaticum 

 and Pi. j'/'i'i"/(nr,i. 



T. sesleriae Juel forms similar stripes on leaves of Sesleria coerulea. 



T. striiformis (Westend.) occurs on leaves, leaf-sheaths, and stalks of 

 .\/j>ecurus, Anthoxanthum, Milium, Holcus, Arrhenatherum, Briza, Poa, 

 Dacti/fis, Festuci.t, Bromus, Agrostis, Lolium, etc. (Britain and U.S. America).

T. sphagni Nawaschin 2 was once regarded as a second form of spore of 

 Sphagnum. 



T. oryzae Pat. The fungus to which this name was given forms 

 sclerotia in the grain of Oryza sativa (Rice) in Japan. 



Brefeld 3 found that dark spores are given off from the surface of the 

 sclerotia. These spores, on germination in nutritive solution, produced a 

 septate mycelium which, in dilute solutions, gave off pear-shaped colour-
