Well, it seems that the Missouri material originally signed to sp-T06 is VERY

distinct genetically from the Texas material assigned to the same taxon. Moreover the Texas material may include more than one species. So, I have been peeling onions to get to the concept of the Missouri material alone. I created a new name as you can see above. The Missouri taxon (collected in Camden and Jasper Counties) has the __penetratrix like “preamble” to nrLSU. The Texas material does not and may, actually be more than one taxon. I went back over all the data. The variety in the sequences is the reason that I never posted any of them to GenBank. They just didn’t seem to belong to one taxon. Now that I have gotten a slightly clearer idea of the provisional series Penetratrices, it is very clear that the former sp-T06 sequences fell on “both sides of the dividing line.”

I have decided to maintain the sp-T06 Texas collections in a single group for the time being, but I think it is very likely that that the concept will break up further.

I emphasize that only the Missouri material that was field-assigned to sp-T06 is included under the new name.

It will take me awhile; however, I have started splitting the old sp-T06 web page. The new justicei page is being assembled here:

After a more detailed analysis, I am convinced that the large subunit…

sequence from this material matches precisely the one we have from an earlier attempt to derive that sequence from Missouri material of sp-T06 from Ha Ha Tonka.

Very best,

Very cool. The landowner will be fascinated by this info Dr. T!

Thanks for sending the voucher material, Jon.

Unfortunately, the “proposed fungus barcode” gene is in three pieces….

However…the species is another member of the __penetratrix_ group with its odd “preamble” to the large subunit sequence. The closest thing on the MAO website is Amanitasp-T06,” and this might even be that species.

If it is “sp-T06,” then it is another species shared by Missouri and east Texas:

See what you think:

We have DNA. A long sequence from the nrLSU region.

Looks to be interesting data.

More in a bit.

Very best,

We have recieved this material and it has been accessioned to Rod’s herbarium. We are scheduling it for DNA sequencing.
