no image, no information.

everyone’s loss.

just went to read about Gymnopodae on RET’s site (after Ian’s recent heroic post of a spider-guarded amanita), and Rod cited the photo here as a possible example of A. ochrophylla. went to view it here but alas, real data destroyed.

deja vu, all over again, eh?

no worries Rod, I still don’t blame you for Noah’s actions. Credit where credit is due.

Somebody voted top level of certainty for the name giving Cleland’s name with three “L’s”. If you reduce your vote on that name, I can delete it. Cleland’s name should have only two “L’s.”


This seems to be a typical species of the Gymnopodae.

Noah’s image shows a naked bulb with distinct memberanous limb wrapped around the stem base. At the time of Bas’ thesis, only two species were known in Amanita subsect. Gymnopodae. Bas had access only to dried material of A. ochrophylla, and he had a watercolor by Corner in addition to dried material for A. gymnopus. He illustrated A. ochrophylla with drawings of dried specimens. Hmmm, perhaps, if my scanner were working, I should put these drawings (Bas is a fine mycological illustrator.) on the Amanita Studies page for ochrophylla. Take a look at the currently unillustrated page for a description of A. ochrophylla.

I didn’t mention this before, but Bas says characters in common in subsect. Gymnopodae are the limbate volva at the stipe base, the naked bulb, a very weakly defined skin on the cap that results in the volva remaining bound to the cap by hyphae (the warts don’t fall off easily), ochraceous [various shades of yellow-orange] gills, flesh that stains reddish, and “a strong unpleasant smell.”

Therefore, one could make a good guess at IDing a mushroom as a member of the Gymnopodae (although, perhaps, not to species) by macrocharacters in the field.

From Bas’s drawing of A. ochrophylla it would seem that it exhibits what appears to be a double-layered annulus. Such a feature is suggested by Noah’s first photograph. Noah’s first photograph also shows the bulb of his find, which is elongate with a broader upper part and a narrower lower part. The same form of the bulb is shown in Bas’ drawings of exsiccata. I think we could, perhaps just for the moment, put an ID on Noah’s illustration of A. ochrophylla with a relatively high ranking of certainty (maybe not the highest). I just don’t have time to go over every character during tax prep. time. Another thought: the bulb in the second photograph shows no volval limb. Bas shows one exsiccatum without a volval limb in his drawings of A. ochrophylla; so, apparently, it can become lost.


Fungi sp. L. (19968)

Gerhard, I dont think so because I have photographed a similar image to this one on my old property at Kundabung NSW . What you have shown is probably more likethe description. This leaves us with the delema, what is it?. Rod has taken the fungi onboard and will try and unravel the problem. So we will have to wait & see, unless someone else solve s the naming. Many thanks Chow, kk
