Caloplaca obscurella - spores

Calolpaca obscurella. To finish the genus Caloplaca, there are several more species for which I have no photo, I am showing this photograph of spores that I examined to confirm the identification of Caloplaca obscurella. These are typical Caloplaca spores, and the separate cells at either end of the spore joined by a thin septum are excellent at confirming the genus. All Caloplaca spores are variations on this theme.
