is the friable UV (breaks up into warts on the cap, leaves crumbly remnants at the stipe base, or nothing at all) in combo with the membranous PV.

love your OZ finds, Ian! Keep on postin’.

To see a lot of images of species of section Validae, here is …

a good starting place:

http://www.amanitaceae.org?section%20Validae

Also, this page is almost up to date for Australia’s amanitas:

http://ww2.tullabs.com/amanita/?Australia+and+New+Zealand

The following taxa are known to be missing at the moment: A. drummondii (section Vaginatae), A. quenda (sect. Lepidella); these species were just recently described from Western Australia by Dr. Elaine Davison in the journal Nuytsia.

Very best,

Rod

though I had to go to the more observations page for clearer representations of this group. The four representations don’t make an immediate impression.

Thanks for the mini-lesson.

This is another one of the set of examples of amanitas that don’t have…

free gills. The attachment of Amanita gills covers a significant range from not attached at all (even distant) to rather strongly attached.

Very best,

attenuate rather than truncate (squarely cut off). This is not usually the case in species of sect. Amanita; so the possibility of this material belong to sect. Validae has to be considered. I’m inclined to start off my voting by suggesting sect. Validae.

I’d like to see this one.

Very best,

Rod

Though being a dug up specimen I was unsure…

makes it unlikely that this taxon is in the pantherina group.

I think I see a striate cap margin; so there is some chance that this species would be in section Amanita as is A. pantherina.

More in a moment.

Very best,

Rod

very small though
