I'm guessing it's a common species of Penicillium mold. Have you smelled it? It could be Aspergillus too, but they smell gross instead of that nice earthy fungal smell. Umm... in mycology we should not attempt to identify fungi only by smell, so kidding! lol
Although I grow several species of Penicillium on my home made cheese and dried salami from commercial cultures, some species are still known to have mycotoxins that can make you sick or worse if ingested. Do not risk eating it. Many people have serious allergies from the spores of even edible yummy species, so I'd avoid bringing it indoors and letting it fruit in open air within your kitchen.
Edit: Fleming must have peed his pants when he accidentally discovered penicillin by running a sloppy lab. His bacterial culture plates weren't doing well because they were invaded by a blue-green Penicillium mold that was a contaminant, and they shit penicillin to compete against bacteria. In nature, it's a never-ending war between bacteria and fungi. It's funny how certain ground breaking discoveries happen sometimes.
