I agree with Amanita karea, it was found in association with Podocarpus totara and Kunzea ericoides, usually the colour of the stipe in A. nothofagi is white and is smooth below the annulus and the scales are rarely concentrically arranged like in this specimen, the non-sulcate pileus and stipe surfaces and non-appendiculate pileus margin would also suggest A. karea following your key!
Thanks for pointing this out Geoff, I don’t think I collected this specimen but will search through my herbarium specimens and add a micrograph of the spores if I can!

Amanita karea and host association

I’m uncomfortable that this is A. nothofagi as the stipe colouring and texture just doesn’t look right. Couple this with the cap scales in concentric rings suggests A. karea to me – would love to see the spores for confirmation. The forest type from which this was collected will be mixed broadleaf/conifer (podocarps and Agathis) and probably Kunzea ericoides (Myrtaceae) as the mycorrhizal host.

I am also no botanist but I like to study native NZ plants and fungi and have worked in the horticulture industry for a few years, it seems that many Amanita species in New Zealand associate with Leptospermum scoparium.

sorry, i am no botanist/arborist and I know even less about Australian/New Zealand species!

These were found directly at the base of Podocarpus totara, and Leptospermum scoparium which belongs in Myrtaceae.
I think Rod is right, Amanita nothofagi, I didn’t realise the colour could vary so much!
No staining reaction that I noticed, although I didn’t handle them.
The other observation of that species were my images also, Alan posted them for me.
This season coming up I will start making collections and will be able to send dried specimens(if it’s legal) for your study, I am interested in viewing the microscopic features of this genus and will be able to post some micrographs in autumn/winter if anyone is interested!

any other tree/shrub associates other than pine?

Rod’s description page on nothofagi states that this most common of all New Zealand mushrooms is a hardwood (beech and myrtle) associate. Your photo superficially resembles our blushing amanitas in N. America, rubescens and novinupta; any staining reactions in this interesting critter?

How about Amanita nothofagi?

How about Amanita nothofagi? A description can be found at


I’d be very interested in any dried material of Amanita from New Zealand. I’d love to use images like these on the Amanita Studies website, but I require dried material to back up the determination of the image.

Very best,
