Amanita section Lepidella sensu Bas (1969). The gill edges appear to have edge tissue that looks very amanitoid. The cap margin is appendiculate. The stipe base looks somewhat rooting and not enclosed in a membranous volva. The combination would make section Lepidella likely. This could be checked by confirming whether the spores are amyloid and whether the tissue of the stipe contains plentiful elongate, terminal, inflated cells (acrophysalides).

Were ectomycorrhizal trees in the vacinity? If not, this could be one of the free-living amanitas. One of these was described from Brazil: Amanita grallipes.

I haven’t looked at that page for some time, but I know that sequences of several loci were extracted from a grallipes collection.

Very best,

Rod
