zinnia spots fungus?

I have never had a problem with zinnias misbehaving but this year, spots galore!! See the picture. Just started about 1st week in Sept. Looks like black spot on steroids. Could be a similar fungus I guess.

Thanks for thoughts. It's been a very humid summer - Also have noticed grasshoppers on the plant. They eat stuff so don't think this is their doing.
