Is iodine used to distinguish fungi?
The history of iodine use for identification of fungi dates back to the mid 1800s; its use for white spore identification was described by Melzer in 1924. The production of the positive amyloid reaction is due to an amylose-iodine complex.
What are amyloid spores?

How do you make a spore slide?
Carefully add a drop of immersion oil to the top of the cover slip before moving to the highest magnification (your oil-immersion lens), and then turn the coarse focus knob very gently and carefully until your spores slide almost into focus. Use the fine focus knob to make them completely visible.

What is lugol’s test used for?

Can I put Betadine on ringworm?
