just for fun…

and to demonstrate that weird morpho happens, here’s an example of a striate phalloides margin from Mike Wood’s website:


That phalloides was at a younger state of development than the mushroom shown here!

Specimen access could have cleared up the entire debate quickly. All else is speculation.

Good IDs require back-up material. Of course, it won’t always happen, but then, we can’t expect to really know our mushroom from just a macro-photo, esp. a photo that shows so many ambiguous characters.

It’s an imperfect world.

too many ambiguous features here…

The cap is fully expanded, not young. I’m sure that you have also seen striate phalloides. UV warts can disappear with time and conditions.

I agree that it looks more typical for a gemmatoid amanita, but the UV on the bulb is more membranous than we’d expect to see for one of our gemmata types.
I actually proposed section Amanita, gemmata group as an ID earlier this am, until I read Rod’s remarks and looked harder at the UV on the bulb.

Then, I wasn’t so certain.

Spores would tell, but alas…

At least we can all agree that this is not a vaginate amanita and that it would be a poor choice for anyone’s dinner.

Scurf and striation

Yeah, both “happen”.

But the well-developed (not random and irregular) character of
not one, but both features (especially the striation/sulcation) on this
fruitbody (that also appears to be fresh) lends more weight to their
inherent presence for whatever species this is.

I agree that it appears gemmatoid.

“scurf” happens…

as do striate margins in normally unstriate amanitas.

Here’s a scurfy phalloides:


however, my first hit on this amanita was something in the gemmata group.

that’s why I was asking about habitat…to my knowledge, phalloides has NOT escaped into the wilds of WA.

IMO, insufficient info to make a good determination here.

I won’t ask about odor, either, since our observer was apparently ill at the time, and sniffing fungal bouquet was probably not on the top of his to do list.

Thank you, Christian.

The rather scurfy-scaly stem and clearly sulcate cap

suggest not A. phalloides

where was this growing?
By: Debbie Viess (amanitarita)
2013-07-08 10:26:34 CDT (-0500)

in the forest or near human habitation/parkland?

what was the elevation?

did the cap have embedded radial fibers, typical of phalloides, like this one, here?


Glad to hear it.

I am feeling better thanks =)

I’m very sorry to hear you weren’t feeling well.

I hope you’re feeling better.


No, no, no

We didnt eat it. I thought it had a sack not bulb, I was pretty sick at the time, wasnt focusing on much else other than making it back to the car.

I hope no one ate this mushroom.

It looks like A. phalloides.


Your specimen

appears to have a bulb and what looks like an annulus which would mark this as something other than section Vaginatae.
