My bag of mulch has white specks in it that looks like powder. I don't
recall seeing it on there last year. Could it be some sort of fungus?

Could be. But even if it is, there are approximately 1.5 million species
of fungi out there, very few of which are pathogens. In fact, I've had
fungus for both breakfast and lunch today... yeast in my bread.

Chances that the fungus in your mulch will be pathogenic to your garden
plants are pretty low. Most likely it's one of the wood-rot fungi,
busy turning your mulch into compost.
