Observation 67671: Agaricus deserticola G. Moreno, Esqueda & Lizárraga
When: 2011-04-22
Who: Byrain
Herbarium specimen reported

Notes: Found growing from a lawn where the grass meets the sidewalk. The base stained yellow instantly. Smell not offensive, possibly chemical-smelling (I failed to record my impressions at the time and I recall it wasn’t a typical chemical smell). Sadly the picture angels are a bit lacking.

The darker spots on the backdrop are chocolate brown spores that covered everything as soon as I started arranging the specimen for the photo.

but it has an almond odor, too!

some beautiful buttons just came into the LAMS meeting this week, where I was their speaker. I brought them home with me, and they will be at the BAMS meeting this Thursday night.

Have fungus, will travel. ;)

Still bright yellow

I’ve been going though my dried collections and noticed the stem base of this is still bright yellow!

Not yet, but soon.

Been going to all the wrong places to get some, I’ll order it online if I have to. I should still be able to test the reaction with dried material? The yellow staining also got more intense then that last picture and is still fully visible on the dried material, I’ll take a picture tomorrow.

That yellowing

is rather intense, though… Arora only mentions sort of equivocal yellowing for A. deserticola/L. texensis
It’d be interesting to see how bright the yellowing reaction was with KOH. Do you have any?

Thanks Christian

Looks like it to me.

Longula texenis, which is now called Agaricus deserticola, apparently.
