I don't save fan leaves myself, so I try to throw all that stuff outside sooner than later. But I sometimes dry my trimmings and popcorn buds to use for hash. A couple times I left those trimmings on the drying rack for a few weeks. I thought they would just be nice and dry and crispy. Instead they were somehow degenerating a bit and there was a whole a lot of dust everywhere. Maybe it's some sort of mold that lives in dry conditions. I got the same thing if I leave foliage laying around too long. So, like I said sometimes I just dry them a bit then toss them in the freezer.
