And thank you.

Well-documented collections of the Vaginatae are of particular interest because they represent one of the great areas of the unknown in the map of amanitas…as in the early (and later imaginary) maps that had large blank areas off to all sides with annotations like “here there be dragons.”

Very best,


Thank you

Thank you for all of the tips Mr Tullos. I would be glad to send this one as well.

If this dries well, I would be interested in seeing it.

I think a big knife or a trowel might help you with the excavation of the stem bottom. Amanitas tend to be inserted (old fashioned word) in the soil to surprisingly different depths. It takes a sort of archaeological approach from a little distance away. If the substrate allows it, I sometimes excavate down one side of the speciment to find its bottom and then remove the mushroom with a lump of soil to protect the base during excavation or work around the mushroom in the ground once I know where the bottom is. Amanita magniradix and the Vaginatae with bases as much as 8 inches down in the ground are a great test of patience and caution.

Very best,
