The N. AZ caesar has much more than just a yellow cap margin. It is paler and more yellow over-all, even white in places. I will be curious to see how they come out genetically. Or maybe I will just run the material that I collected this month.
Still need to hit the scope.
…been released. Consequently, I just know things like some GenBank accession numbers and don’t know the data itself.
Last night I went through my herbarium data base with regard to this collection and several others from which Bob sent me DNA. It looks like these collections were not sequenced. Possibly they came along too late in the research process. I can’t remember.
In the third part of his thesis research, as I understand, Sanchez-Ramirez was focusing on the fact that the genes revealed a complex of taxa closely related to A. jacksonii. He tackled the genetic data for this complex with statistical methods and found several taxa. Many of them tend to have a yellow cap margin at an early stage of development (not a result of fading from red to yellow).
These new taxa are in addition to any taxa that have been posted to date on WAO.
Maybe sometime a little later this year we will know more.
If so, I am not surprised that there is color variation.
So, basii is “very similar” to “cochiseanna?” Like how close? 98%? Closer? Maybe there is only one species involved, with different color morphs and a broad range? After all, the US states where these orange western caesars get collected were Mexico at one time.
I remember you saying, Rod, that basii wasn’t very tasty, and that porcini had to be added to a dish in Mexico to give it flavor. My experience with our N. AZ collections was very different … the flavor was fabulous, all on its own. The odor fresh was fruity, David perceived a “peachy” smell.
There were abundant fruitings in AZ, enough to feed a family of five and voucher several. Written up, drawn, and photographed. They were the reason that we went to the SW this year, and I was not disappointed.
somewhat further north in the U.S. and southward into Mexico that was sequenced by Sanchez-Ramirez was either cochiseana or basii regardless of cap color. And those two species are very, very similar genetically. Of course, that doesn’t mean that someone won’t find anything else…. The most recent (large set of) sequences posted to GenBank by Sanchez-Ramirez were not yet released when I checked a little while back.
They should be released this year when the third part of this thesis is likely to be published.
Bob and I were just discussing the possibility of a second SW caesar (in addition to the very orange Chiricahua caesar, nom prov “cochiseanna”), that shows a far more yellow and even whitish cap. I collected these yellowish caesars recently near Flagstaff, will post obsie soon.
BTW, they are a delicious edible … much better than either of our CA coccoras.
This material has been recieved and accessioned into Rod’s herbarium. We have scheduled it for DNA sequencing.
