Is this ok on the wood for mamajuana?

Just came back from Dominican with a bottle of mamajuana (just the wood in a bottle). Got a bottle of crap rum to soak the wood for a few weeks before making it. After pouring in a bit I noticed what looked like mold/webbing. After it got wet it looks a little waxy. Guessing I got a bad bottle (🤬). Hoping someone here can help with what it may be and next steps (which I’m assuming is to junk it)
