WHAT IS IT? Black moulds aren’t the most charismatic of life forms, but this one is worth getting excited about. It’s a new species belonging to a new genus of a whole new family of black moulds. Unfortunately, Aeminium ludgeri also happens to be threatening a UNESCO World Heritage Site.
WHERE IS IT? Mycologists might disagree, but it’s probably fair to say that, for the rest of us, the fungus’s habitat – the carved limestone features of the 12th-century Old Cathedral of Coimbra in Portugal, which are crumbling as a result of the infection – is more pleasing on the eye than the mould itself.
