Types of household mould

Grouped by what you should do rather than by taxonomy, because that is the question being asked. Note that three entries here are not fungi at all.

Not mould

Mistaken for mould constantly. Ruling these out is often the whole answer, and none of them needs remediation.

Worth investigating

Either a signal of a serious moisture problem, or a known allergen worth removing promptly. Not a reason to panic.

Clean it, fix the damp

Common indoor moulds. Clean the growth, fix the damp, and they do not return.
