Peteh, T., Note on the biologv of the genus Septobasidium. 

 (Annais of Botany. XXV. p. 843. July 1911.)"" 



Species of the genus Septobasidium (a fungus allied to Thele- 

 phora) frequently cause alarm by clothing the stems of tea bushes, 

 mangos and other trees in tropical regions. The author shows that 

 in Ceylon the fungus always grows parasitically on colonies of 

 scale insects, which are overgrown and destroyed; and that at least 

 one American species shows the same peculiarity. It is the scale 

 insect therefore and not the fungus which causes damage.

 1911.) 



The author adds another species to the genus Sorosphaera 

 (Plasmodiophoraceae) and describes it in detail. The new parasite, 

 5. Graminis, he finds in the roots of Poa annua and other grasses, 

 usually in Company with eelworm. No hypertrophy takes place, the 

 root-nodules near to which the organism is found being caused by 

 eelworm and not by Sorosphaera. Infection usually takes place by 

 penetration of a mononucleate amaeba into a root-hair. but wound-
