The red stain on the last

photo seems an aberation, but I can probably check /collect tomorrow. I have never heard of that type of staining – except possibly on A. rubescens…, Which I will also post tomorrow. It is definitely a unique subtype compared to what I have seen elsewhere.

Is that a red stain on the stem in the last photograph?

Did you cut the flesh and seen a raspberry sherbert red stain?

If you have the material wrap it in wax paper and then quickly open the wrapper and smell the collected odor. Is it like licorice(anise)?

I think you may have Amanita mutabilis.


Very best,
