Spore deposit color; dark brown-smoky brown Stalk length about equal to cap width, 2cm long,

slender and bare near apex, thickening suddenly about 5mm down from the apex or about 1/5 the length, to about 4mm wide(thick)where the surface changes,

ID is probably as good as it’ll get for now.
I think the other one looks larger and yellower. Just mentioning it so we don’t get the impression that there is only one Agaricus that looks like this.

I wonder if Agaricus trisulphuratus

is smaller…
This was a rather small specimen, I have a dried specimen, if looking at it under the Microscope would help?

There’s also this guy

It had been dry for some time then it started to rain and this was one of the first finds,

gorgeous little Agaricus…

found in Southern Asia as well as Africa.

If I had to pick 600 fungi from around the world on the basis of their showiness, this little guy would definitely make the cut (“The Book of Fungi,” pg. 36.)!

Your depiction is nicer than the photo in the book, tho, Johann.

Nice find.

I just googled it

It was fun… :D

That’s a friggin’ sweet mushroom, man!
I would imagine that mushroom hunting in Tanzania would be pretty awesome.

Links are broken….

Johann, your links do not work!

Thanks, And Good Call indeed, Tim

I wouldn’t have guessed that it was Agaricus for awhile more likely I would have guessed Stropharia like it has been called in times past http://www.google.ca/...

Here you can see a picture of one…
Mine seems to be quite small perhaps since it was early in the season (not much rain until this time) and there was only one.

cool find!

I thought "Wait, I have seen a funky, scaly, yellow Agaricus recently!

Thanks Christian!

Good call, Tim!

One thing that book has going for it is lots of exotic stuff. Some weird IDs in it, though.

Alan brings up a good point

but, I think, as Johann said, that they are supposed to dry out to brown.

Could be a straight-up Agaricus, I suppose. The extreme shagginess and bright pigment would be a bit odd.

True but

but they turn brown, they start out reddish or greenish and then turn brown

I thought Melanophyllum was supposed to have reddish spores, these seem too dark.

Oh Wow! Really!

That is exciting, glad I have a dried specimen, I will have to check it out.
