Distinctive tropical genus (also a “physcioid”). The pattern of pruina is distinctive: near the tips, but stops a little way back from the margins. Also the yellowish medulla is typical (and unusual in most other physcioid genera). Chemistry is very rich in this genus (as in most tropical genera, it seems, you lucky dogs). The clincher is the “lecideine” apothecia; all other physcioid genera have gray (“thalline” or thallus-like) rims; this genus has black rims without any algae. (Hmm, I wonder why that’s helpful?…)
