Some type of parasite or fungus is on and around the dahlia plants at my mother's. It has been hot and dry so wood chips were placed around them. We thinks the chips introduced this attacker. It looks like scale, but I'm not sure because it is on the name marker tags too.

I've attached two images. One showing a leaf and the other a brown dahlia stem with a few small weeds at the base; it also shows the plant marker tag and wood chips covered.

Does any one know what this is and how to treat it?

Looks like a really bad infestation of a fungus, I just dont know which one. If you haven already gotten rid of all the wood chips I would do so immediately and throw in the garbage, not in a compost pile. I'm sure other members will have better advice for you, Good Luck

My research came up with candlesnuff fungus. I would do what Christine suggested. Others may have a different solution.

Thank you for your help. I will treat a few areas for fungus and see if it works. It isn't tall or have any height like candlesnuff fungus. It looks similar to small gray and black poppy seeds.
