I went back and cleared the base of this mushroom of litter. No cup that I could see… Just a bulb.

We received your dried material just before Christmas. It is accessioned in our herbarium and will be scheduled for sampling for DNA extraction.

Happy New Year.


The new photos show a bulb typical of porphyria.

Nice shots.


If you have not collected and dried a specimen before,…

don’t worry if it doesn’t work out. That’s the first thing. It takes a little preparation and some experience will help you.

It’s very kind of you to make the offer of helping in this way.

I’d like to send you a little pamphlet that includes information about drying. If you email me using the MO email function, I’ll have an address to which I can send the PDF document.

Very best,

Rod Tulloss

I took pics of the bulb, not a cup…
I will try to collect one, and send it. I went back yesterday for another pic. I am sure they will last until I get back.
I have never done that before…

If you have the time to collect and dry some of this material and send a specimen east,…

I will put it in our schedule for sampling material for sequencing.

this is the beauty of MO: real work in real time to get real information!

not that I don’t enjoy a nice speculation right along with everyone else…;)

More shots

I will go down to the beach and take more shots, hopefully, today.

woulda helped a lot in its ID, tru for any amanita. We need a basal volva for confirmation.

But…from what I can see, especially the gray coloration on the annulus and the powdery UV remnants on the cap, I would suspect that this amanita is porphyria, which can have a dark purplish brown to paler gray-brown cap, and always has a gray veil.

The base on porphyria is an abrupt bulb without a membrane; on phalloides (which never shows a gray annulus) it is a rounded bulb with a loose membranous sac.

check out other photos of both of these species here on MO to get an idea of the differences.
