This material has been recieved and accessioned into Rod’s herbarium.

I’m very interested to see if the pale cap color consistently corresponds to a specific one of the three citrinoid amigos. My current thought is that this is A. americitrina. I’ll give myself a cup of expensive coffee if I’m right. :)

Very best,

Rod

This was a really nice fresh specimen.

So I wanted to get it into the dryer quickly. sorry no spores. But I do have the material, Rod, and you will soon receive the specimen.

Do you have a shot of the spores?

My old observations on spore size and shape among citrina-like things are lining up with the genetic results from Dr. Hughes’ work related to the lavender- or amethyst-staining hybrid that she discovered. I’d like to see if we can put a name on this mushroom in this observation by using the spores.

A. The true f. lavendula has broadly ellipsoid spores that are rather small…check

http://www.amanitaceae.org?Amanita+citrina+f.+lavendula

and

http://www.amanitaceae.org?Amanita+sp-lavendula02

It now looks as if those two pages (above) describe the same taxon.

B. The pallid cap of the present observation is starting to look as though it is associated with a rounder-spored taxon that appears to be represented on these two pages:

http://www.amanitaceae.org?Amanita+sp-lavendula03

and

http://www.amanitaceae.org?Amanita+brunnescens+var.+straminea/...

C. The third possibility is the hybrid which is represented by this page only:

http://www.amanitaceae.org?Amanita+sp-lavendula01.

A combined sporograph on the technical tab of the sp-lavendula03 page, provide a direct comparison between the ranges of spore size and shape for the three taxa.

Very best,

Rod
