84 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
When this Richards’ solution with the same celluloses as the 
sources of carbon is solidified with 2 per cent agar and inoculated, 
the diametric growth of these same 5 species of fungi is slow. It 
is characterized by а very thin superficial layer of mycelium and 
by clearing of the agar, denoting utilization of cellulose. Тһе 
growth in diameter, both of the fungi and of the clear zones, was 
measured every other day for 18 days, when all growth had 
stopped, due to the drying of the agar. Аз the intervening 
measurements simply show successively increasing growth with- 
out any striking departures from the normal, the final figures, 
as obtained at the end of 18 days, are the only ones ев presentei in 
table xv.
