not a good match to griseofolia as described:

From http://www.amanitaceae.org/?Amanita+griseofolia

“lamellae: free, crowded, whitish (Cream Color, 1A1-2), but soon becoming grayish to gray (Pale Smoke Gray to Light Drab, paler than 5D2), often becoming somewhat darker when dried.”

The cap is fully expanded, and was dried in place. IF this grisette was griseofolia, there should be gray coloration present in the gills, by now.

“pileus: lacking any yellow or ochreous tint at all stages of development.”

I can clearly see yellow tints on this cap.

This is an interesting grisette, but I don’t believe it to be griseofolia.

I would suggest that you evaluate Amanita griseofolia as a possibility.

Your material was drying in situ when photographed. Some color changes may not have had time to take place before the drying process began.

Amanita griseofolia was described by Prof. Dr. Zhu L. Yang in Agerer, R., M. Pieppenbring and P. Blanz, eds. 2004. Frontiers Basidiomycote Mycol. (IHW Verlag, Eching): page 315, figs. 1-7.

It was originally described from Kunming, Yu Quan Gong Yuan (Jade Spring Park), Heilongtan (Black Dragon Pool). Although I had the pleasure to collect briefly with Dr. Yang in that location, I have never seen fresh material of griseofolia.

At any rate, I’m very interested to see your posting of this observation.

Very best,

Rod Tulloss
