There are three taxa that become “lavender” or deeper purple in cold weather.

These have been separated genetically, and we are approaching the ability to tell the taxa apart morphologically.

The developing knowledge is spread over three pages at present on the Amanitaceae Studies site:

THe sp-lavendula03 page listed below and the similarly named pages with URLs ending in




At present we believe that the latter is the species that now goes under the name Amanita citrina f. lavendula. It does not belong under the European “citrina” concept and is a good species on its own. All these corrections take time to happen. From the Amanitaceae website, you can see that the sp-lavendual03 is more pallid than sp-lavendula02 and has spores with a distinctly different shape. That is to say, we can tell the species apart morphologically.

Very best,


Thanks for the notice about the error, Willow.

I think I have corrected the second URL so that it works.

You will have to cut and past the first because the error is introduced by MO.

Very best,


Thank you, Rod.

I managed to copy/paste your URLs since they’re broken on MO. But the second doesn’t seem to work for me.

I did hear mention of the “lavender towards winter” citrina, but I gathered it was the same thing. Good to know it’s not.

The very pallid cap…

suggests that this is a species that will become lavender in cold weather and now has the name A. brunnescens var. straminea. This name will change in the next year or so. The mushroom is a good species and is much closer to A. bulbosa (aka citrina) than it is to brunnescens.

See the following pages. All of the present evidence suggests that these two pages described the same species:

[The above requires cut and paste because of an apparent MO problem.]


The smell you report is typical for all the taxa in both the brunnescens and bulbosa “groups.”

Very best,
