Good sample to have on hand for comparison material when you aren’t sure about if the lower surface of something is corticate or not. The most useful character here — though I’m sure other species do this occasionally, too — is the strikingly white and abundant cilia. This is typical for H. speciosa. I see this character used in several keys, although it makes me cringe each time. Maybe it really is reliable. I just find that very surprising. I remain skeptical.

Lower surface white, may or may not be corticate (hard to determine for me – it’s somewhat fibrous but firm), rhizines white. Soredia labriform, going over the lobe tips onto the underside.
