cellar walls disintegrating?
The mortar in the stone walls of my cellar appears to be crumbling/shedding dust. Is this something that presents an immediate hazard? What is the fix? Any experiences?

Can anyone recommend a mason for dealing with crumbling basement mansonry?
I agree, not a good idea to trap moisture. Theroseal by name makes one think it is a waterproofing material. I don’t think it is, I think it does air. I have not had any problems with it ( yet ). However, these products are made for specific situations & conditions and should be handled with care.
Use the proper mortar mix, problem solved.
We have the same issue with a stone foundation/basement walls, but were told by a structural engineer that its better to leave it alone so as not to trap moisture behind the wall.
Get yourself a mason
still not a good idea to trap moisture inside your walls though.

Actually, if it is stone wall it is not nearly as bad to seal the inside as if it were a brick wall. Stones do not need to breath like bricks do.
Rick, you’re creating a HUGE problem for yourself. You aren’t stopping the shedding, you’re simply trapping it (and a lot of moisture) behind the paint. 9:56 is right, masonry needs to breath, on the inside AND the outside. It’s a porous material. If water can get in, it also needs to get out.
OP should contact a mason. It sounds like this problem could become serious, but that its fix (perhaps improving drainage outside of your building to make sure that water is directed away from this wall, or installing a dehumidifier in the basement) might not be so bad.
