What is this white moldy thing?

[PashkaTLT]

Found it on the trunk of my Windmill that I received yesterday and on my European Fan Palm I received 1-2 weeks ago.

Checking with a 10x magnifying glass and 20x pocket microscope didn't reveal any moving things.

@GDLWyverex there are no observable bugs. Nothing was moving. I could easily see 1/100 of an inch with my microscope. Maybe it's not obvious, those are macro photos, made with a good macro lens. Or you mean they were here and this white stuff is a byproduct of their life cycle?

Here's some scale for reference:

I now think it's tomentum.

My chamaerops humilis always has this especially the new leaves or the spears, I think it's normal

That's what I would vote for.  It's odd to see that on old fronds, though.  The Windmill pics kind of looks like some white mold on top of old brownish tomentum?  You could hit it with a bit of 3% hydrogen peroxide and see if it fizzes up.

Yeah, I was going to say that it's just normal palm stuff. If you want to see this on overkill look up Brahea 'super silver'.
