Hello,

Without a picture it is difficult to tell what these might be, although it does sound like it might be artillery fungus. I've included a link to a page about artillery fungus- you may want to google search for images of artillery fungus on homes to see if that matches what you have.

I am also including a link to a page that lists various methods individuals have tried to remove the artillery fungus.
