Given that I do many things with my russulas (you know… the peeling, tasting, looking for forked gills, coaxing them to drop spores, dropping FeSO4 or guaiac tincture on them, throwing them against trees, going blind trying to measure their spores and warts, etc.), don’t dry or eat them. :D
In all honesty, cannot recall if this thing changed colors overnight. As soon as I saw a good spore print, it promptly went into a trash can. Why? What did you have in mind?

Did this Russula stain black at the edges when it dried?
