You might have scale insects. These look like a little 1-2mm limpet for want of a better discription.
They attach to the underside of the leaves and stems and exude a sugary substance which attracts a fungus called sooty mould. A quick wipe with a cloth soaked in a leafshine product, dilute milk or dilute fairy liquid should clean it off.
The scale insects are a little harder to cure and you used to have to brush each one with meths. I'm sure that if scale is the problem, you'll be able to get something in the local garden centre.
If it's not scale, you might have had aphids or mealy bug (looks like a white wooly woodlice), both of which attract sooty mould.
Good luck
