Mushrooms are not meant to be harvested with a tool.
They are meant to be gathered.
However, if you have Admin access, you could go into ghost form, sink into the terrain and you could harvest them with a pick, all of them. Obv. that method would count as cheating.
However, it is still possible to harvest them with a pick regulary with no cheating methods, just need to find shrooms on a small hill terrain surface where you can stand lower than the shrooms.
In my opinion, it would be better if they would allow harvesting shrooms with a tool like nearly everything else in the game. Just increase the height of the shrooms hitboxes, problem solved.
But Community Support clearly said shrooms are meant for gathering only. No idea why.
