Observation 102406: Amanita farinosa sensu Thiers
When: 2012-07-21
Herbarium specimen reported
0 Sequences

Growing in a small open area under maple, hemlock and Douglas fir, about 50 m from Sunset Rest Area. The place was covered with oxalis and other plants and the mushrooms were mostly hidden.

I cut one lengthwise before putting them in the dryer: there was no noticeable odor.

just how close is it to the eastern farinosa, DNA wise?

GenBank has assigned an accession number for the sequence from this collection.

This collection now has a sequence number posted on WAO. In a matter of weeks, the sequences will be posted on GenBank for public access.

Very best,


differences and similarities confirmed!

now, who is gonna name this thing?

The “sequencing race” was won by Dr. Geml’s lab in Leiden.

Thank you, Sava. We have received a good “propoesd fungal barcode” sequence for this material, which is consistent with the sequences from other material from California and Oregon. We appreciate very much your sharing this material with us.

Very best,


Yes, I do have the material…for which I’m very grateful.

To answer Debbie’s question about sequencing:

A lot of material is off for sequencing to Dr. Yang’s lab in Kunming and to Nhu Nguyen in Dr. Bruns’ lab at UCB.

The Chinese team is comparing all known possible “close” relatives to farinosa that they can get their hands on—at least two loci each.

Nhu is running barcode or barcode-like sequences for eastern and western North American collections.

Yang’s lab usually holds its data until they are ready to publish.

The sequences from Nhu will be posted on WAO as soon as we finish the necessary post processing and make sure the sequences are telling a coherent story. At the moment, we do not have a target date for the raw data’s showing up in Roosevelt.


gorgeous Sava!

I missed these when they first came up.

Rod, are you (or rather some local lab) running the DNA on these, to see how it compares with eastern farinosa sp? We couldn’t ask for nicer, fresher material.

Thank you.

I was able to attend all information that I needed.

Sunset Rest Area is on US26, at milepost 28.6; about 31 miles east of Seaside. The map with coordinates is at http://www.lat-long.com/....

Thank you!


You give the collection area as 50 m from Sunset Rest Area.

What is the route number or name of the road on which that rest area is located? Do you have a lat./long. for the rest area?

Very best,


Thank you, again.

The material has arrived in good condition.

The mushrooms are in the dryer now and I’ll send them to you. I also added a picture from which we can measure the sizes.

Very nice pictures. All of them. I love the close up of the universal veil.

Cristina and I would like to see your dried specimen of this species if that is possible.

Very best,
