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

Thanks for the report, Ron.

Rod, yes I did make a note

about the orange patches on the stem. This was a pretty mature specimen, so that may have something to do about the quantity.
When I found this lone fb, fruiting along side a nice little A. flavoconia that was just posted, I debated whether to even stop as they are relatively common.
They were picked but only the spore print and the A. flavoconia survived the dryer.

The spores and the photos look good for jacksonii.

I think I see orange patches on the stems, which look a little washed out in the photographs. Did the stipe have more distinct orange fragments on it in real life?

Santiago Sanchez is worrying through whether he has found some sort of subdivision within A. jacksonii in his genetic studies. There might be a benefit from sending a gill sample from this collection to Santiago. I’d be glad to do that.

Very best,
