If you choose another oxidizing agent than CrO3 (such as KMnO4, potassium
permanganate) it's up to you either to find literature to back you up, or
to do the stain with appropriate controls for the fungus you're looking for.

Thanks for your reply Gudrun,
I agree with your statements. If KMnO4 used as a replacement for CrO3, it
should be used under much milder conditions (low temperature and less
incubation time) than H6IO5 as KMnO4 is a stronger oxidant. However, my
question was due to the fact that KMnO4 was a comm
