These large blooms looked like they would be identifiable but my limited lichen literature (and even more limited lichen ID skills) have failed.


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

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

Species interactions

No interactions present.

Great images

I'd have been tempted to have a stab with Flavoparmelia caperata but for the absence of any wrinkling and what look like apothecia in the close up shot. I'm looking forward to finding out what this is.

I hope I've captured enough detail to let someone ID it - the journey back to Shetland from London to take another picture would be a long one.

Always very difficult to identify lichens when they are soaking wet.

However, having checked by downloading the images and putting them into Photoshop to adjust the colour, I am happy they do look like Parmotrema perlatum.

Good call by Synangium.

Parmotrema perlatum?

The recording software I use (MapMate) does not have Parmotrema perlatum in its taxa library. Does it have a synonym?

Parmotrema chinense.

In MapMate: Parmelia perlata

Mapmate is a real pain for lichens. Names are way out of date, some are absurdly wrong, and recently recognised but very common species such as Caloplaca flavocitrina are not included.

My MapMate installation is for another purpose (and paid for) but I am trying to use it also for lichens in my own area and it really is difficult/frustrating.

I've been asking the 'MapMate Help' guy for years when there will be an updated version of their lichen database but it doesn't seem to be one of their priorities!

I think MapMate updates are prioritised in part by how many people are asking for a particular update. So if there is a definitive Lichen check-list then the more lichenologists who ask MapMate the more likely it is to be done.
