Observation 24170: Amanita amerirubescens Tulloss nom. prov.
When: 2008-07-17
No herbarium specimen

Notes: Note controversy over gray veil on Dan’s recent amerirubescens posting:

I dug thru my photo files to locate this image from last summer. definitely a “rubescens”, and definitely has a gray veil. it had been raining buckets in Boone, so maybe the veil sometimes turns gray when it gets water-logged?

I don’t know either…

But yes I do see variation. Variety alba is common and seems pretty consistent. Its staining is slow and usually not covering most of the fruiting body. There is the gray warted one and the buff warted one and another that seems to have yellowish veil remnants. I discussed these with Rod several years ago but I don’t know what his current thinking is… They are a challenge.

I can’t answer that question.

My Eastern amanita collection experience is limited and long distance.

How much variation within species do you see in the field? I certainly see quite a bit here in the West. Without side by side fruit body comparisions, macro and micro, don’t see as how we are really going to get a definitve answer, at least on these mushrooms. Perhaps this darker variety is in search of its own species name? Who knows? Not me…

I apparently already posted this image last summer, and Rod gave it his highest confidence level for an Amanita amerirubescens ID! Link here:


OK Walt, but any idea what it might be instead? looks like the NE “rubescens” to me…

but certainly my eastern amanita collecting experience is limited, and ridiculously limited compared to your own.

no specimen, so this will be pure conjecture, but I do know exactly where I collected it, and could have my on site Boone buddy go find more…always glad to push that learning envelope!

Debbie, I think this entity is different than A.amerirubescens. It is not rare in E. North America and I do not think the gray is caused by environmental factors.
