the lower half of the stem. Amanita flavoconia doesn’t do that. It’s bright yellow volval material is much more loosly attached to the mushroom and any sizeable fragments not on the cap and not left in the substrate are usually rather sparsely scattered on the stem or just a very thin layer of yellow pigment or lost through handling of the mushroom.

Very best,


Thanks! Very insightful!

Looking at the photographs I thought this might be A. muscaria var. guessowii. The spores proved to be inamyloid and the right size for var. guessowii. That is the name under which it will go in the herbarium. Thanks very much for the material.

Very best,
