Titanium spider dropings

[snowman682]

Dont know if you get them where you are at, but here we occasionally get little dark brown spots on homes. I think they are spider droppings, but holy cow do the hang on!!!! Hence the title. I have thrown everything I have at them and nothing. Only thing I have found is getting right on them with hot water, and they come off. Just have to watch the damage factor on siding. Oh, and when there is about 200 on a side of a house, that adds a little time. Any one have any suggestions or hints? Thanks

It may be Artillary fungus.
