Spent quite a bit of time today in LFay working on this, and came up with some facts:
The ground spawns have a respawn timer of about an hour. It's hard to lock it down to a precise time because of the number of spawns to watch. I would say definitely 55 minutes to 1 hour. At the 1 hour mark, they appeared to have all respawned.
I found (repeatedly) 12 ground spawns in the Faerie Camp, 11 ground spawns in the Brownie Compound (3 inside, 8 outside), and 11 ground spawns in the Undead Monument area. I could not find any ground spawns anywhere near the Pixie Tower. And I don't believe I ever have.
For the day, my ground spawns yielded the following:
203 - Sarcoscypha Fungus (+/- 1)
79 - Jack-O-Lantern Fungus
2 - Blue Slumber Fungus
I recall Blue Slumber Fungus being more prevalent in the past. I'm wondering if the lack of this type has something to do with the game time of day I harvested them or some such. The two I got were at the same "respawn session" and both in the Faerie Camp.
