What it really means
Black or green spots of fungus that grow in damp places — around windows, in bathrooms, behind wardrobes. It can affect health, so report it to your landlord in writing. British spelling is "mould"; Americans write "mold".
Chinese explanation
潮湿处滋生的黑色或绿色霉斑——常见于窗边、浴室、衣柜后。霉菌可能影响健康，应书面报告房东。英式拼写为"mould"，美式为"mold"。
Example conversation

A：浴室窗户周围长了黑霉。
B：书面报告——并要求房东处理根源问题，而不只是擦掉霉斑。
