Foraged purity questions

A few purity questions.
Is there purity in hollow stumps? I don't think I've seen anything above 0% come out of a stump with 30+ h&g.
What's the deal with inspirationals like brilliant honey-dew and perfect autumn leaf, is the purity and element the same as the object you picked up or can it be different? I can't confirm this but on retrospect I think a I grabbed a waxing toadstool with 2% purity and a honey-dew spawned in my inventory at 4% purity with a different element. Are these inspirationals even effected by proficiencies, since they spawn in inventory?
For instance would f&w effect the purity of say rainbow scales? It's obtained from a fish, but not from fishing per-se.
Anyone have any insights or observations here?
