A high concentration is better, 10% or 20% is much safer.

1,7? Can you show a narrow spore like that?
Your find is Mollisia olivaceocinerea (Svrcek). This is a fairly mobile complex that is phylogenetically divided at least into Mollisia oblonga and nodosa. I cannot tell the difference between these two species either by eye or by microscope.

Dead spores are much narrower than vital ones.
You've just shown the best example.
Here is another example. Look at the spores top right:
