How credible is that? The claim that moss from an asbestos cement

And so it ought.

Go to an asbestos roof, peel off a clump of moss, look at just what is
underneath stuck to it.

presumably some sort of analysis was required here? e.g. were they
perhaps moss "roots" you're remembering?

wiki advises:-
"industrially-processed chrysotile usually has shorter fibre bundles.
The diameter of the fibre bundles is 0.1–1 µm, and the individual
fibrils are even finer, 0.02–0.03 µm, each fibre bundle containing
tens or hundreds of fibrils.[3]"

that looks pretty small to me.....
