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

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

 two years more they lose their capacity for germination. 



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

 Secale cereale. 



T. decipiens Pers. (Britain). In fruits of Agrostis vulgaris 

 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 Lolium 

 perenne, and of L. temulenium (darnel-grass). 



T. hordei Korn. occurs in grain of Hordeum fragile and H. murinum in 

 Persia. 



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



T. calospora Pass. In grain of Andro-pogon agrestis in Italy. 



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



T. olida (Eiess.) forms stripes on the leaves of Brachypodmm sylvaticwm 

 and B. pinnatum. 



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



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

 Alopecurus, Anthoxanthum, Milium, Holcus, Arrhenatherum, Briza, Poa, 

 Daetylis, Festuca, Bromus, Agrostis, Lolium, etc. (Britain and U.S. America). 



T. calamagrostidis Puck. On leaves of Calamagrostis epigaea, C. Halleriana 

 and Triticum repens. 



T. epiphylla Berk, et Br. Stink-brand of Australian maize. 



T. Fischeri Karst. In fruits of Carex eanescens in Finland. 



T. arctica Eostr. On leaves and stalks of Carex festiva in Finmark. 



T. thlaspeos Beck. In fruit of Tklaspi alpestre. 



T. zonata Bref. On Sporobolas ligalaris from Quito. 



T. (?) glomerulata Cocc. et Mor. occurs in Italy on leaves of Cynodon 

 Dactylon, Plantago lanceolata, and Medicago. 



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

 Sphagnvm. 



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

 sclerotia in the grain of Oi-yza sativa (Rice) in Japan. 



Brefeld^ 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-
