Herbarium Amanitarum Rooseveltensis/Rod Tulloss received specimen

We have received the dried specimen and it is being accessioned for our herbarium. Thank you very much.

and here I thought

it was going to just be another boring “rubescent” one. :)

It’ll be in RET’s capable hands soon, so it will be fun to see if we can settle it.

A bit different…

than what I call “saloniolens” around here. Fruit body larger than usual. But other features match well.

The subglobose bulb is unusual in the Vallidae outside of series Mappae.

Amanita submaculata has a distinct odor. It ranges from apples or pears to (rarely) anise or (very rarely) a brand new rubber tire.

The reason (I think) that it was called “submaculata” is that the color on the cap has little openings shaped like human eyes with the long dimension aligned radially. That is, there are little white eye-shapes scattered on the cap.

Do these field cues help you?

Very best,

Rod

I have to say though

that greenish pallor seems exaggerated as well!

I probably should have taken another shot of the cap out of the direct sunlight.

YES! I find every time I put them on the table and flash them (collected for RET) my Amanita specimens take on a LOT more contrast!

The cap photo in the field is much more what I actually saw.

so …

you are saying in natural light the cap is really a pale brown with a darker, umbonate center??!
I assume the striking greenish color in the field is merely an artifact of light and surroundings.

It is certainly an amanita in section Validae. Color and morphology and the lack of a potato odor makes me agree with Erlon’s original ID.

Submaculata also shows red staining in the form of streaks at the stem base. I found other collections of submaculata online that show very similar bulbous (but not cleft) bases.

I suspect the rest of the evidence, yet to be analyzed, will prove this to be submaculata.

Nice find!

Thank you, Geoff.

I’ll take a look when it comes around in the queue. :)

Flash and natural light shots are very different!

The flash really darkens up the caps I’ve found! All my field shots are long exposure with natural light.

The bulb does not appear to have any splits, nor does it smell like potatoes.

This one is in the dryer for your disposal (you meaning RET)! :)

The bulb is nearly globose.
By: R. E. Tulloss (ret)

And the cap is very brown. Until I registered the size of the fruiting body, I was going to suggest solaniolens; however, this is too big for that species.

Are there vertical splits in the bulb anywhere. If you split the bulb, does it smell like potatoes?

Amanita brunnescens is another early season possibility.

Very best,

Rod

quite a color change

from field to home.

That A. submaculata looks really good! I was going with the red staining!

Thank you Prof. Baker!
