Observation 196610: Amanita kundabungii Tulloss & Kudzma nom. prov.
When: 2015-01-15

Notes: Majestic specimen (of Amanita?),that took me by surprise. Single fruiting body in open ground area after light rainfall. Area had canopy and filtered light. Eucalyptus & Semi-raiforest.Fruiting body well exposed above forest floor except for the volva.. Soil was loose and damp. This fungi had some unusual attributes. The pileus was oval following on from the area where the Stipe and gills met. The stipe had a flattened physical attribute from the volva to the gills. I checked the surface area where the fungi was found, and could not find any restricting composition of the soil to cause the stipe’s flattened condition.. The gills were close, delicate and easily damaged. When placed on the forest floor the gills separated as shown in the images. The stipe flattened effect may be associated and natural habit of this species?. I have not seen this flattened effect before!. The Gills were laid face down on white paper and I think the spore print was white. (I did not leave the cap too long before drying, as I did not want to loose it). The Cap had three distinctly coloured areas. Dark in the central zone and each zone becoming lighter towards the outer perimeter. The outer edge of the cap had a distinct grooving habit. I also noticed that where the stipe meets the gills there is a separation . I believe this was caused in the handling of the fungi which I have noted was very delicate in the pileus area especially. The stipe did have a firmness that was noteable.
Al images, (photos), are white balanced to daylight, with white balance card. Light was filtered indirect, and No Flash was used. The "White Balance Card shows 18% grey, and two measurements. i.e. 1 (one) CM and 1 (one) inch.

Camera settings ISO 100@f25 2.5 s Lens 105 macro f2.8 max aperture. No Flash, Filtered light.

After Ian’s note about Kundabung,…

I submitted a spelling correction to MO. The name should be kundabungii. (meaning the place with wild apples according to Wikipedia).

Very little data is here: http://www.amanitaceae.org?Amanita%20kundabungii

Sorry for the hash-up.

Very best,

Rod

sorry about the continuing drought in your region, Ian.

perhaps you can follow the CA lead … we have finally finally gotten enough rains to fruit the MR species. Amanitas and everything else are exploding out of the ground. Sadly, the introduced and invasive Amanita phalloides (OZ also has the “pleasure” of this introduction in the Melbourne area) appears to be dominating the woodlands, even possibly displacing some of our native species, like our edible and enormous California chanterelle.

Some additional technical notations added. See last loaded jpg.

Note added to image with White Balance 18% card measurements, for following descriptive notes.
Also added some technical notes in first descriptive notes. ISO 100 @f25

I would not bet on the flattened stem and oblong cap happening again.

We need to stat building up data to go with the photos and tne DNA.

We need to deduce dimenions from your photos, and write a macroscopic description as best we can. We need to put the sequence in GenBank so that we might hear if someone else finds the same species. We need to get a good description on line. We need another collection if that is possible.

We are scratching the surface. We can also try again for sequences of other genes from the material that we have in hand.

Very best,

Rod

Truly surprising

RET,
Rod, what is the next stage & part of naming this magnificent Fungi? Thank you for the great efforts in deciphering our Down Under surprises. I was in awe when I found it, but first thoughts were it was a morph. I think Debbie mentioned this earlier in the notes. Is it any value to bisect the volva at find. Wednesday here and had our first Summer Storms. Hopefully will see some fungi on the mountain. We still have not had sufficient rain for “Run-Off”.

We have received sequences for this material.

The nrITS shows a rather distant relationship to A. penetratrix, but it is the closest relationship with any material that has a published or provisional name. It is very interesting that the nrLSU sequence begins with the same unusual motif that was found in A. penetratrix. (For brief notes on this motif see near the bottom of the technical tab for the latter species:

http://www.amanitaceae.org?Amanita%20penetratrix

You will see that two other species from SE Australia with provisional names also share this motif: A. punctata sensu A. E. Wood and the provisional A. myrmeciae.

This is very interesting material. (I admit to finding the odd motif attractive.)

Very best,

Rod

Thanks Ian,

This material has been received and accessioned to Rod’s herbarium. We have also scheduled it for DNA sequencing.
Thanks,

I was, of course, kidding …

about a provisional name of “compressus.” Just riffing on its flattened appearance. Despite the lack of evidence in the field, it is probably just a morpho variation of a not usually flattened grisette species.

If “punctata” (now cheelii) is distinguished by a discretely “dotted” stipe, this one doesn’t fit.
Ian’s example here shows typical grisette chevrons on the stipe. Many grisettes can show graying gills and have two-toned caps with a darker center, and there is no sign of what the inner volval sac looks like.

Who knows what this will turn out to be?

There is a possibility that this is one of the taxa that have been called “punctata”…

in Australia. The name has had to be replaced (by Amanita cheelii). (Cheel was a co-author of the Australian A. punctata nom. inval. and co-authored many papers with J. B. Cleland a superb early 20th Century Australian naturalist.) Australian field guides describe a species under the old name that is different in appearance and spores size/shape from the Cleland and Cheel species (cheelii). With some of this material in hand we can make a reasonable statement as to whether or not this is the true cheelii. A study of the type material of A. cheelii is reported here:

Very best,

Rod

very nice documentation of an oddity, Ian.

perhaps we could give it the provisional name: Amanita “compressus?” ;)

Beautiful, Ian.

I look forward especially to this beauty.

Oh my goodness it’s a definite Yes. Exciting isn’t it. kk
Have parcel to prepare for you in few days. I will email you when on its way. Hope you are feeling better.

I agree. Majestic is the word.

I hope I will have a chance to examine it.
