Isolation of Geotrichum sp.'s spores

[C.C.Chen]

I use malt extract agar slant to cultivate  Geotrichum. After 3 
days of growth,
I use 1% triton soln to wash the slant getting the spore suspension.
But when I cultivate it in the ME agar again. I find that only 5 spores
are germinative. I use LM to detecte it finding that there is many spores
cross-link together.
How can I getting the spores suspension?
And how can I getting the mono-spore ?

THANK YOU!!!!!!!
