tiny, sooty dots EVERYWHERE

I have been growing roses in the same bed for 35 years here in Marin County, California, north of S.F. Near-organic, spray only once when I prune in late winter. Gradually, the blackspot has almost disappeared (I maintain scrupulous garden hygiene), rust almost the same. But this year, for the first time EVER, I've got tiny, VERY black, sooty dots of some kind of fungus all over the backs of my leaves! Have not sprayed except with some baking soda, which didn't help much. Also, I have seen this same fungus (I'm assuming it's a fungus) in my neighborhood, like on tree leaves. Should I worry, or is it something seasonal that will go away? (Have coped by cutting off all affected leaves.)
