@fuzzyI'd suspect it's not too much to worry about if the plant itself is healthy. It'll either be algae/moss (in which case, scrape it off and replace a little compost if necessary) or some kind of fungus. Water it with a decent systemic fungicide if that's the case. Or dilute copper sulphate solution.
