Description: At first glace the beginner may be inclined to think that this grey, foliose species is a Hypogymnia with perforations. Yet this is not that far from the truth and one would be tempted to suggest you hang on to this image. M. terebrata is a much sought-after, much photographed species, this I hasten to add, because of its beauty. Its extraordinary elegance makes it a Ferrari among lichens — the beautifully adpressed rosettes with branching, radiating lobes glinting like mirrors. The scattered perforations and the spotting of soredia cut an additional dash of detail into the uniform. Discs are rare. Spot tests: K+ yellow, Pd+ yellow-orange. On leached, acid bark, mostly on trees in the west or on mossy boulders in humid woodlands.

Key Identification Features:

• Like a compressed Hypogymnia physodes drilled with perforations and spotted with soredia
• On the leached, acid-bark of trees in high-rainfall woodlands of the west; very beautiful forming radiating rosettes on trees.
