Found a few of these objects called "Sunlight Threshcone" on the ground while adventuring in the fields outside Cetus on Earth. The thing doesn't seem to be interactive in any way; I can't pick it up, shoot it, melee attack it, or do anything else to it that I can think of.
What is this?

The Sunlight Threshcone is a scannable object that is used so far only in the Mission The Silver Grove and a few consumable types.
It is used for a few of the recipes and objectives in the The Silver Grove mission which the player is required to craft to progress, and in the recipes for Antitoxins and Apothics.
3Threshcones are used to craft apothics used in The Silver Grove (both during the quest itself and after completing it)
That are a way to gain several Aura mods (and a couple of stances) as far as I remember.
