Parasitic Habits of the Plasmodium of Physarum viride var. 
rigidum. — A. R. Sanderson {Trans. Brit Mycol . Soc., 1922, 7, 
299-300). Notes were made by the author on the habitat of this 
Mycetozoon in tropical Malaya. Usually it was found on decaying logs 
of Hevea brasiliensis, and frequently on or near the pilei of Schizo- 
phyllum. Sanderson found that the plasmodium grew over the pilei 
and killed them. It grew also abundantly on Hirneola, but failed to 
develop on Daldinia , Nummularia and Ustulina ; when transferred to 
these fungi the plasmodium died. A. L. S.
