We do have a complete sequence of the “proposed fungal barcode” from the material reported by this observation.

So we have two very nice sequences, which are being prepared at this moment for deposit in GenBank.

Very best,


As always, thank you very much.

My rules are that photos for the website have to show the material from the same collection of which I have part or whole.

I was so glad to see that we had sequences from your material.

Very best,


Thank you Rod!

And Happy New Year! I’ll check if I sent you the measurements for this observation and if I haven’t, I’ll sent them over. I’ll also check if I have some nicer photos.


We just recently received new DNA data with 2 sequences from this material.

This material is a very, very good match to material of A. marmorata that was imported to Hawaii and South Africa. In both cases new names were created; however, on morphological grounds I had argued that both names were synonyms. This collection seems to make a third line of the triangle. This material from this observation is very strongly supported as being A. marmorata.

A very cool find from the point of view of a guy very far away.

Happy New Year, Lucy. Thanks for sending this great material.

While we didn’t get a complete nrITS (proposed fungal barcode) sequence we got over 1300 characters of the nrLSU sequence.

Very best,


Thanks Lucy,

This material has been received and accessioned into Rod’s herbarium.

It is so cool to see this species and your other material from Little Hartley.

Impressive collections.

Very best,


Yes, I agree with your email that this looks like A. marmorata.

The pattern of the cap is distinctive. My concern after seeing material with this patterning with Australian-origin trees in other countries, is whether there is color variation in one taxon or more than one taxon.

It would be interesting to know whether the shade of gray on these caps is constant in the material you see.

Very best,
