On hard oat agar, culture twenty-eight days old; conidia from a large 

 (3 millimeters in diameter) sporoclochium :

Average of the above measurements for all non-sporodochial conidia: 

 Conidia: 0-septate, about 9 per cent, 11 x 3/i 



1-septate, about 11 per cent, 16.5 x 3.15/Lt 



2-septate, about 2 per cent 



3-septate, about 20 per cent, 32 x 4.1ja 



4-septate, about 8 per cent 



5-septate, about 41 per cent, 52 x 4.2/i 



6- to 9-septate, about 9 per cent, 45-84 x 4-5.8/1 



The organism when first isolated had large sporodochia (from 2 to 5 

 milhmeters in diameter), and the substratum and mj^celimn near it were 

 from rose to pomegranate in color; later the color of mycelium and sub- 

 stratum faded and no sporodochia were produced at all; during the last 

 year its original characters — both color and sporodochia — reappeared. 

 Under just what influence loss of characters and their reappearance took 

 place the writer is unable to say, although it seems that a slightly acidi- 

 fied and relatively dry medium actually helped to bring the fungus to 

 the original conditions.
