No specimen available

I hope I’m finally getting a feel for this lichen. Fairly small greenish-gray or whitish-gray surface, with small, short whitish raised ridges, lobes 2-7mm across, some black circles visible on surface; multi-layered, top: gray-green to white, middle white, bottom coal black; inrolled on the sides. A few white rhizimes appear as spots on the reverse. Haven’t done a bleach test yet, but did collect this sample for testing later.
