Heterodermia propagulifera  

Similar to Heterodermia obscurata but with a thallus with narrower lobes and a different chemotype (norstictic acid, atranorin, zeorin), resulting in reactions of C–, K+ yellow→red (crystals), KC+red, Pd+ orange and UV–. Further research is needed on the identity of these populations.
