Watching results with interest & awe

Rod, Thanks for the link to Observation 102465: Amanita sect. Vaginatae sensu Zhu L. Yang. It really does add interest in the procedings. Can can only watch and wait in awe.

The roll continues.

Amanitawilliamsiae” is a member of the “TCT…” group.

Thank yous are posted on the above observation.

Very best,

Well, we got on just a little bit of a “roll” yesterday.

beginning of nrLSU can be found at the end of the discussion data field here:

Amanitasp-AUS08” is the first, known, brightly-colored member of the group (athough we suspect that Amanitawilliamsiae” will turn out to be another yellow species in the group).

One more thing.

So sp-AUS08 becomes still one more member of section Vaginatae with the unusual first characters (5’ motif) of the nrLSU gene that we originally saw in A. penetratrix and are now finding in many parts of the world.

Here is the 5’ motif shown in the context from which we recovered it. It begins at the eleventh character in the following string:


The initial TTATGATTCA is the end of the “proposed fungal barcode” in the present species. The remainder of the above is the beginning of (the 5’ end of) nrLSU.

Very best,


Well there WAS more to find out.

I was able to recover about half of the “proposed fungal barcode” gene and discovered that strongly matches with the same piece of the “barcode” gene from 202072. The yellow-dominated taxa of this observation and 202072 seem to have a high likelihood of being the same species.

Whattaya know?

This species seems classifiable as Amanitasp-AUS08.”

Very best,


However, I can see in one of the reads that the LSU 5’ motif is the TCT…

Maybe there is more to be said here.

We did not obtain good quality sequences from this material.

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