Observation 197641: Amanita “sp-AUS12” Tulloss & Kudzma cryptonom. temp.
When: 2015-01-30

Notes: White (Cream) Cap, Gills and Stipe.. Stipe tapers towards bulbous base. Gills close. Fungi in loose soil on forest floor. Area Eucalyptus forest. I noticed some green substance in the base area. It appears to be an algae or growth of some description.

Recognized by sight: Unusual morphology (dull colors, cap striations, no PV, and a sack-like volva) originally suggested sect. Vaginatae; however, the stipe is not totally elongating and actually has a bulb hiding under the well-developed volval flaps/limbs!

Info update most appreciated. Interesting and teasing heh. kk

We have received some DNA information on this species.

The limbate bulb in the phots suggests the possibility that the mushroom is pantherinoid (similar to Amanita pantherina). This is consistent with the DNA. Using the BLAST program to compare the sequences we got from your material, the closest match is Amanita parvipantherina, which was described from China originally. The match is not close enough to say that you have parvipantherina in Australia. The Chinese species is just the closest “relative” that has had its DNA posted to GenBank. We got a complete nrITS sequence. The nrLSU data is in two disconnected segments (both, separately, producing the same closest match).

This information is consistent with the species having inamyloid spores. Some further work is required, but I thought you’d like to have some feedback.

Very best,

Rod

Thanks Ian,

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

Specimen dried

Will include. Rod I am using a backup PC whilst my main PC is having a major upgrade. Would you be so kind as to send me the postage details again, as I DO NOT HAVE ALL MY MAILING INFO ON THIS P.C.. Can you PLEASE INCLUDE THE SPECIAL MAILING NOTE that you provided me with previously. (scientific use only etc…)
Hope to get all packages completed and posted mid week. It has been a major exercise this time around. Some exciting specimens for all. Again thanks for your time. I know only too well that it is such a controlling factor in getting all one wishes to do, completed. Kind Regards, kk

I checked Wood’s monograph.

He doesn’t list a strictly white or cream capped species in the Vaginatae for New South Wales and Queensland. So this would be that much more interesting to examine.

Very best,

Rod

In the first image,…

it looks like pulverulent material descends down the stipe without interruption from a partial veil. Maybe the gap in the second image is due to handling? At any rate, I’d go for sect. Vaginatae at the moment and then check myself later with the dried material…that is, if you would be so kind as to pass on some of the material observed here. More in a minute.
