White hairlike fuzz (it's not mealybugs) on den canes

[KatieM]

Hey, guys! I have lurked for so long on here and decided it's time to post! My Den Smillae is getting these white hairs. I've actually seen it before on some of my vegetables as well (none present currently anywhere but here). This was originally potted in a bark mix and the leaves fell off so I put it in a live Moss which I have found has really helped keep fungus at bay. I know it's getting ready for hibernation time but they didn't fall off in a way like they usually do. Is this fuzzy stuff a fungus possibly? Everything I looked at shows a more powdery substance but I'm not finding anything that shows these more hair like types. Any ideas on what it is so I can figure out how to treat it would be great! It's been outdoors in the sun getting plenty of light hasn't been too damp and I'm in Northeast Florida. I literally just received my first ever bottle of physan today so thinking may be worth spraying that but would like to know what I'm fighting first.
