section of the genus from the same “teaching topic.”

I hope the samples will be of use for something besides showing how my handwriting is deteriorating. :(

Thank you Rod!

I will definitely try to find more of these next weekend and I will take notes & pics properly. I was able to download the form for taking notes last time I tried and then made lots of copies so I have plenty to keep me going for a while. I am very excited about this one!

I was going to say you can download forms for taking notes on Amanita

But then I went and tried to use that function on WAO, and it didn’t work.

Folks! Please, I want the WAO site to work for you, not screw things up for you. Please tell me if something is not working. It must have been months, at least, that this thing has been busted.

I have recoded the page and it is now true that if you go to the “teaching topic” (upper left of any species page) about forms for note taking, you will really be able to download samples of filled-out forms and a blank form that you can copy as much as you want.

Please spread this around on other blogs and discussion groups.

Very best,

R

This is cool.

See if you can get a shot of one with a straight stem. More shots of cap pigmentation would also be very interesting. I think there is a chance that this is distinct from A. marmorata. If that is true, we need all the macroscopic details that we can get.

Very best,

Rod

The cap has a monotone approximation of the pattern in Amanita phalloides.

Of the known taxa that belong to sect. Phalloideae or probably do in Australia, there is one that has a pattern such as is shown in Lucy’s pix. That taxon is A. marmorata (which has a number of synonyms such as A. reidii).

So far as we know all species of the Phalloideae that have this pattern of cap pigmentation contains one or more amatoxins. So…DEFINITELY don’t eat this.

We have a page for marmorata here:

It doesn’t look exactly like your species, but it seems that it might be a relative.

Very best,

Rod

Interesting. Hi, Lucy.

The short gills are a mix of truncate (squarely cut off) and attenuate (diminishing in width smoothly). There is a partial veil remnant on the stem (see last photograph which shows a fold in the partial veil where radially lines on the top of partial veil are going in two directions and meeting on what must be a fold in the p.v. It looks like a bulb is present and it looks like there may be a volval limb on the bulb. If these observations hold up for younger eyes than mine, then I’d say we’re looking at something from section Phalloideae. Hence it might contain amatoxin. Please don’t eat this, Lucy. :)
