Observation 181535: Amanita wellsii (Murrill) Murrill
When: 2014-10-03
No herbarium specimen

Notes: This collection was made by my wife, who visited the area to pick cranberries.

The gills were distinctly yellow. Second photo, which was taken indoors under fluorescent light best approximates the color… although perhaps a bit too vivid. First two photos taken indoors, last three outdoors one day after collection.

Grains on gill edges interesting. These were not collected from an area with sandy soil. So I don’t think the grains originated in the substrate.

Same location as obs 16428 . Last winter I checked this area thoroughly for blueberry bushes. There are none near the collection site. Cranberry bushes, shrubs, small gray birch, very small native spruce.

This material has been received and accessioned to Rod’s herbarium. We have also scheduled it for DNA sequencing.

Well, David, other than experience extreme cranberry envy, I see no reason why…

you shouldn’t ship as per your current thought.

Thank you very much.

Very best,


I visited the collection site today.

Found the (presumably) exact location where these mushrooms were found by finding another specimen of wellsii which looked as though it had been hiding under the grass before expanding somewhat after yesterday’s (10/4) rainfall.

To my surprise, there are blueberry bushes (Vaccinum) growing along the trail (old railroad bed). Both sides of the 10 foot wide trail are bordered by a thicket of 15-20’ gray birch trees mixed with a few maple saplings and blueberry bushes. No spruce trees in the immediate vicinity. Mushrooms were growing on the grassy trail. Originally (a few years ago after obs 16428 was collected) my memory had placed these a couple hundred yards down the trail.

The two seen here have been preserved and packaged along with other materials. Rod, unless I hear from you that it would be better to wait, I’ll put the package into the mail tomorrow afternoon.

Picked over 6 quarts of cranberries today :-)

I’ll mail a package soon. Lots of goodies to send, including the A. pachysperma.

Very nice.

Congratulations to Mrs. W. and the cranberries.

Were you able to dry the material?

I have a chance to get wellsii material sequenced right at this moment because of sheer luck regarding the availability of students for DNA sequencing and the current stage of the Agaricales Diversification (“3000 agarics”) Project. Amanita wellsii happens to be one the species to be sampled in Amanita.

Very best,
