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

good ole Mum.

your description of a “tough texture” also sez amidella to me … but we’ll just have to wait and see.

nice job in sheparding this specimen. Do please change your obsie to reflect that fact, otherwise we amanitologists can get a little weepy. so unseemly.

My guess is that this is the same species as in 89165.

The cross-section associated with 89165 shows no partial veil and no bulb. It is clear that the original color of the cap when first exposed by the breaking volva is white.

I checked to see if by accident (or something) I actually had material of 89165. But no. It’s marked on MO as having no voucher; and I don’t have anything in the herbarium numbered 89165. So…no chance to check for amyloid spores or anything else.

We’ll have to wait and see what your mum has wrought.

:)

Very best,

Rod

Pine trees

The pine trees are the same ones that I find the muscarias in. They are imported but I forget where from. There were also a few eucalyptus trees nearby (3 metres). Other than the muscarias, the only other amanita I have found so close to the pines is MO#89165, which was in exactly the same spot as this one actually.

Unfortunately my mum did not take a photo of this one cut in half.

I saw this as a baby/young adult and asked my mum to water it and collect it (because I had to leave) when it grew more. It definitely isn’t old. I had never come across this one before, which is why I really wanted it. My mum reports that it has dried perfectly and now in its sealed bag. I’ll add a photo my mum took of the gills, just to show that it wasn’t old. It had a much tougher texture than other amanitas I had come across, to the point I wasn’t sure it it was an amanita. I’ll answer your questions better once I’m on a computer.

too bad you didn’t save it, Lucy.

who knows what wonders will turn up in OZ? It reminds me a bit of this amidella from Portugal. Your example is a bit old and dry, and who knows what features have been lost or created over time?

You do have MR species with your eucalypts, right? If introduced pine, from a random continent, who knows what all came in along with it?

Hold on.

Now I see parts of the cap surface are whitish in the second and third images and there seems to be a pink tint on the vertical edges of the volval fragment on the cap when the are seen in side view in the third image.

Is the brown on the cap some sort of stain? Can you help me interpret the cap coloring?

Very best,

Rod

This is interesting, Lucy. ……. EDITED for spelling

There is a distinct reddish stain on the lower stem. I don’t see evidence of a partial veil. The margin of the cap is striate, and the stem base is enclosed in a volva. A cross-section will be interesting to see in order to clarify whether there is a bulb inside the volval sack.

Because of the red on the stem, I checked A. rosea (a species either in section Amidella or in Bas’ stirps Preissii of section Lepidella sensu Bas). However that species has a cream cap with pink tint as well as elements of the volva on the cap which are probably from the inner surface of the volva and are more intensely colored that the surface of the cap:

So we can set that aside. If there is no bulb in the sack, then this probably should be placed in the Vaginatae; otherwise, it would very likely be in section Amanita.

Do you recall the reddening stem in material you have previously collected? Also, when you say “Pine” are you referring to an endemic group or imported trees of the genus Pinus?

Very best,

Rod
