How to Identify Parmeliaceae

Key Identification Features

• The combination of firmly attached sparsely branched tufts, abundant apothecia at branch tips, and no detectable lichen products are key features used to identify C.
• The underside of the thallus ranges from white to pale brown, paling in colour toward the centre of the thallus, and is distinctly wrinkled.
• Parmelia discordans and Parmelia pinnatifida are species that are morphologically similar to Parmelia omphalodes, but are genetically distinct from it.
• perforatum has a naked white zone on the underside of its thallus margin, and typically has long hair-like projections called cilia on the edges of its lobes.
