As Derek says, highly likely to be cushion scale - Google cushion scale and select the RHS page, which gives info and treatment recommendations.

Hi, welcome to GoY, check the leaves, particularly underneath, for aphids or scale insects, A harmless sooty mould develops on the honeydew they produce, it wont do any harm, it just looks a bit unsightly, but the things that cause it may damage the plant, Derek.
