Will my HO4 renters policy cover wet fungi protection?

On my HO 04, what are the limitations on the wet fungi protection with 25,000 & 50,000 dwelling types A ins? What limits do I have to have if my dwelling coverage is $25,000 or $50,000 concerning the HO 04 the wet funGi protection?

I can't answer this question - you need to look at the exclusions and special coverages in your renters' insurance policy dec page (declaration page). That part of your policy will specify how much coverage you have - if any.
