a few days the medium becomes light yellow in colour. Few 
chlamydospores occur. Conidia are formed in fairly large 
numbers. They measure 22—37 ‘5px 12°5—17 ‘5p. 
Jowar leaf juice agar. The growth is almost submerged, but there is 
abundant spore formation. Conidiophores are often angularly 
bent and nodulose. The conidia measure 17-5—30# > 12°5—15p. 
Barley meal agar (+8 Fuller’s scale). The growth is poor. The 
hyphe are dark grey. The medium is dark yellow near the 
margin. Abundant spore formation takes place and the conidia 
measure 25—32°‘5p x 12°6—16°2p. 
Litmus lactose agar (+6 Fuller’s scale). The growth is poor. 
With age, the red colour of the litmus changes into blue and then 
darkens, showing that the medium is becoming alkaline in reaction, 
Few chlamydospores are formed. Spore formation is poor and 
the conidia measure 22°5—32‘54% 10—16°‘2p. 
Dextrose agar (+-2 Fuller’s scale). Growth is poor. Aerial myce- 
lium is little and of grey colour. Old cultures become slightly 
pink. No chlamydospore formation. Conidium formation poor, 
Conidia measure 25—3Cp x 12°5—1bdp. 
Oat meal agar (+2 Fuller’s scale). Growth fair and crowded. No 
chlamydospore formation. Spores form in large numbers and 
measure 22°5—32°5 x 10—16°2n. 
Glycerine agar (+6 Fuller’s scale). Very poor growth. The 
hyphe are almost submerged and the medium turns pink in colour ; 
later on the hyphe become grey. A good many chlamydospores 
are formed. Conidium formation fair and conidia measure 
22:5—32 ‘5x 10—15m. 
Cellulose agar (+9 Fuller’s scale). Very poor and submerged 
growth in this medium. For the first few days there was little 
growth and a few chlamydospores were produced. Spore forma- 
tion is fair ultimately and in measurement the conidia are 25— 
35¢@ x 12°5—17 ‘5p. 
Starch agar (+4 Fuller’s scale). The growth in the beginning is 
poor, but after a few days it improves. The growth is sub-aerial 
with some submerged. The medium becomes dark grey. No 
chlamydospore formation takes place. Conidia in fairly large 
numbers and measure 20—30# x 10—16°2p. 
Corn meal agar (+-2 Fuller's scale), The growth is quite good and 
is pink in the beginning, but later on it changes into dark grey.
