It is unlikely.
When spores first are released they are plump and hydrated.
As time passes (if they are not emersed in water, in water they will degrade and finally break down) they dedicate. They will not germinate unless they are hydrated. If they are dry they must first absorb water from their surroundings.
Remember that a mass of spores go from almost total viability to say, one in two then one on ten, then one I one hundred and you won't notice because there are so many but eventually every last one of them expires
I have germinated five year old spores of shaggy manes. When I soaked them in water for a week first they started within a few days. When I used rather wet agar it took over a week and when I used dry, very solid agar it took over two weeks.
But I cannot recall any spores taking a month. I suspect that if you don't see anything in three weeks you never will.
