Parmelia Sulcata? or Ramalina canariensis?

Found on lime tree in Herbert Park (Dublin), lichen with large pale green lobes - appears to be fruticose, but using keys is most likely Parmelia Sulcata, a foliose lichen. Ramalina canariensis would probably be the most likely if fruticose.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Thanks. In fairness to the

Thanks. In fairness to the key - I didn't expect a fruticose lichen, even though I knew it had that form (I didn't believe my eyes!) -so I went ahead and starting looking at foliose lichens.

and not so illogical!

The distinction between foliose and fruticose is not always clear, and I have to admit it is very easy to think of these broad-lobed Ramalina species as foliose.

The problem is that we are trying to impose a simple, arbitrary classification on a huge diversity of lichen structures, and our classifications do not always work very well. In principle, a flattened fruticose species is much the same on both surfaces. Foliose lichens have an underside that is usually very different in colour, and often have projecting root-like rhizines.

Anyhow, Ramalina canariensis is a good species to see. Probably more common around Dublin than it is in much of Britain, but still a nice find.
