NOTE: I cannot shrink my images down to 150KB to be uploaded here. they may be viewed at either of the two above links.
I arrive with my key at P. farinosa (= P. versicolor), the common one, though the spores are at the upper range in legth.

Thank you for your reply. I am learning to love H20, one mount at a time :)
I had originally thought that the orange to almost faint purple coloration of the apothecia might have ruled out the common Propolis spp., but I see from the photos at
https://drive.google.com/drive/folders/0B5SeyOEkxxZhLUcwdW54dzVGenM
that some of that coloration can, indeed, exist.
Best,
