Is this Collemopsidium foveolatum on the barnacles

Observation - Is this Collemopsidium foveolatum on the barnacles. Description: Looking like small dots on the barnacles, but I couldn't tell if they were raised, flat or sunken. If not just general wear and tear of the shells I think this might be Collemopsidium foveolatum.
