Lichen sp.

A few of these were growing on rocks near the coast, from the limited knowledge we have, we think it may be a Caloplaca species but we're probably wrong! Suggestions greatly appreciated!


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

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

Thanks for identification. As

Thanks for identification.

As we are new to iSpot, we are not sure how best to get a definitive identification on things we will upload.

For example, our second upload has been given two suggestions - of course we understand that some species are notoriously difficult to name but is there any way which would allow us 'lean towards' one suggestion more than the other?

Many thanks.

There are iSpot contributors who have badges next to their names indicating they have expertise in a particular field (birds, mammals, fungi and lichen, etc). (Badge label is shown when the cursor is moved to it.) I would definitely advise you to 'lean towards' their suggestions rather than mine for all iSpot groups!
The 'notoriously difficult' issue you mention with lichens, compared to say birds, seems to be that identification is often not possible from just a photograph. Microscopical examination of parts such as spores is often crucial (or in some cases possibly thin layer chromatography) so differences in judgements from just photographs are likely.
On a positive note, when several possible identities are suggested it makes me realise that what I had previously seen as one sort of lichen may have been several different kinds all the time.
