Would like to have this fungus type of growth identified and recommendation given for removal or treating, as it is growing on the outside window sill of a historical building.

Thank you for your question. I cannot tell whether this is a fungus or a plant. I suggest you take samples to your county Extension office for help. Here is their webpage: Good luck!
