When: 2010-07-06

Collection location: Parque de Monsanto, Lisboa, Portugal [Click for map]

Who: zaca

No specimen available

The general characteristics point to Ramalina. This specimen has farinose soredia, but not oval or disc-shaped as in R. farinacea. The texture of the lobes is also different from that species.


Underside of a lobe.
Chemical reactions: upper part – Thallus K and KC; lower part – Medulla K and KC.

Debe tratarse de Evernia prunastri.

and I find nothing of the kind. Note that beyond the strange mottling, both faces are green. Cracks are visible in the photo with the underside of a lobe.

I’ve never seen Ramalina mottled like this. (Doesn’t mean it doesn’t happen, though!) I wonder if you have Evernia or Pseudevernia instead? Normally those two genera would be white to brown to black underneath, and greenish above. Ramalina should be the same color on both sides of the branches. Also Ramalina is supposed to have tiny cracks in the cortex, although they are often very inconspicuous in my limited experience.
