Joint Session Question---Plasmosis Meditator???

Does anyone know which joint session had the story about the mushroom Plasmosis Meditator, It came to be grown after a plasma storm and was so big that houses could be carved out of the inside of it. 

It was an incredible reading of a mental download and I haven't found where it was, I wanna say Winter of 2020- or so. 

If anyone recalls I would be grateful to listen again!

Also If your near Minneapolis Area, See you at the meet up next Monday 2-5 in Hopkins at the Wild Boar!
