My youngest son is very found of traveling (outside of cities) in Indonesia. I hear many good things from him about his trips (touring)…especially, the food.

Very best,

Rod

the umbo slit easily with a scalpel. Not sure if that proves anything.

I’m off tomorrow for most of July in Indonesia. I promise when I get back I will buy a vegetable dryer!

I think I know this species. Did you attempt to cut it in half lengthwise? Or just attempt to cut it through the umbo?

If so, was the umbo extremely tough and resistive to cutting even with a razor or a very sharp knife?

The large size of the fruiting body and the fact that so much of it was below the surface of the soil, reminds me very much of the group of taxa that I call the Amanitapenetratrix” group. I have only run into this species in the northeastern states; however, it looks like you may have at least one of them in Georgia. If we could confirm this, it would be terrific.

I have had terrible luck with this group. The first day I saw more than one of them (three different cap colors that day), the power went off on the dryers during the night and we lost (essentially) everything—-no useful data obtained. That kind of collector’s “curse” has followed me for six years with regard to “penetratrix.”

What little information is available is presented on this page:

Very best,
