COTTON, A. D., Pure Cultures of Fungi from Orchid 

 Mycorhiza. (Naturalist. 1904. p. 53.) 



A preliminary communication. Abstract of paper prepared ior 

 Corshire Fungus Foray 1903 giving methods of culture etc. The 

 mycorhizal fungus in the roots of various species of Eria was identified 

 as Eusisporium endorhizum (Reissek), this is probably identical with 

 that described by Chodat and Lendner in the roots of Listera 

 cordata. A. D. Cotton.

Febr. 1904. p. 268.) 



This notes the finding of the Sclerotium and filaments of Rhizoctonia 

 in the coats of discolored beans, thus indicating a common means of 

 disseminating the fungus. Hedgcock. 



Hedgcock, Geo. G., Proof of the Identity of Phoma and 

 Phyllostida on the Sugar Beet. (Journal of Mycology. 

 X. 2, 3 Jan. 1904.) 



A cultural study made of Phyllostida taken from the leaves, and 

 of Phoma taken from the roots of sugar beets rotting from the typical 

 Phoma crown rot revealed a similarity in color, dimension, and gross 

 appearance of the mycelium, pyenidia, and spores of the two fungi. 

 Beets carefully grown from sterilized seed were inoculated with the 

 spores from both sources, and similar leaf spots were formed, the two 

 fungi fruiting alike. Control plants remained free from disease. From 

 both sets, leaf spots bearing mature pyenidia were taken and the fungus 

 was isolated again and grown in pure cultures with similar results. Beets 

 whose leaves were diseased with Phyllosticta when placed in a dry 

 cellar, and watched from time to time, after two months had contracted 

 the Phoma rot, the fungus having penetrated the crowns of the beets
