I was looking through pictures with Heterodermia :)

Tricky one!

There are two species here. Notice the cilia are only present on the bit in the lower right corner (yes, I agree, that’s a young Heterodermia), but most of this is Myelochroa aurulenta, I think. Only other pustulate species are Hypotrachyna, which have a rather different look (check for forked cilia and rhizines, that’s the true test for Hypotrachyna in my experience).
