I get quite a kick out of it myself.

It’s a thrill to see the fruits of my walks in the woods become part of the mycological record.

I’m setting up a page for this critter, David.

May I use some of your images?

Very best,

You’re welcome, David.

I’ll have this…

in the back of my mind when I visit this collection site 2-4 times this coming summer/fall.

As always, thanks for the follow-up, Rod.

This taxon does not have the unusual marker immediately…

following the “proposed fungal barcode” gene (as in penetratrix). It is the “standard” one common to the large majority of amanitas.

Very best,

Rod

Well, we got back sequences for the usual two genes…

and this is not A. penetratrix. The sequences are not a particularly good match for anything in our data base. The species is certainly an Amanita of section Vaginatae. We appear to have good, clean sequences.

If I make further progress, I’ll let you know.

Thanks for the puzzle!

Very best,

Rod

You’re welcome, Rod.

I really need to be more diligent about noting details regarding habitat. In fact, I just had a telephone conversation with Igor last night, and he mentioned how using a small hand-held voice-recording device simplifies this process. I guess I’m just gonna need to shed some of my Neadertech tendencies and got up to date with a few of these technological advantages.

Thanks for the additional information, David

I visited the collection area today…

on my skis. No mushrooms, but the trees are still there. This particular part of the hemlock/birch woods which borders a navigable stream does have a few isolated oaks mixed in. I can’t say with confidence that the exact collection location included oak, but it seems at least possible that this mushroom could have been associated with oak.

As previously mentioned, the hemlock/birch woods borders an oak-dominated hardwood forest on the border opposite the stream. There are also a few isolated large white pines positioned near where the hemlock/birch area borders the oak-dominated woods.

Aha.

Thank you.

I brushed back the leaf litter…

so that the insertion of the stipe in the substrate may be viewed.

Oak leaves… The area where this was found was not populated with oak. But the hemlock area that followed the Nescopeck Creek bordered an oak-dominated woods. It may have been close to where the two forest types met.

I thought that it might be replanted because of the density of oak leaves.

These are not mentioned in habitat data.

Very best,

Not replanted.

This is exactly as found in-situ.

I hope to get all my Amanita material together this afternoon, and perhaps mail it to you tomorrow. Does this sound good?

Replanted for photography?

Looks a bit like penetratrix.

We’ve managed to get some of the NEMF2015 samples of penetratriz up on the WAO site.

We are just about send all our penetratrix material for sequencing sometime this week or next.

Very best,
