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

Species with which Cladonia fimbriata interacts

Cladonia sp.

Janet, the discussion as to whether it is C. pyxidata or C. fimbriata is well-commented on by iSpot contributors. Before deciding, I can recommend you view iSpot's own EOL website as well as www.lichens.lastdragon.org/Cladonia and www.irishlichens.ie. Regards

Been there!

I think Alan's and Jenny's sites are fascinating and excellent. Unfortunately I haven't seen the discussion you mention because I usually steer clear of lichens - I find them too difficult. I was charmed by these specimens and made the mistake of trying for species instead of being satisfied with Cladonia sp.!

Janet, thanks for the compliment regarding my site, and I agree Jenny's site is excellent. I wish I had her web design skills.

Also, please DO try for species rather than just settling for "Cladonia sp.". It doesn't matter if you are right or not, and it does show that you have thought about the photograph. This is not an easy group but you have had a go, and not been too far off. Don't let anyone discourage you.

Personally, I feel much more ready to step in with an ID or comment if I feel the person posting has made an intellectual contribution themselves. I am seriously thinking of no longer bothering with those Observations where the sole text is "Lichen for ID"!

Thanks for your encouragement.

Thank you for your encouragement, I rarely post lichens but I am interested and feel more confident to have a go now. I can see what you mean about the fine powdering.
I know it is time consuming but please don't stop making your reasoned explanations of 'for / against' decisions about IDs! I usually read and enjoy them (as I'm sure many others do) even though I haven't agreed or commented myself. I often browse observations and choose to look at lichens just incase you have given a response hoping to learn a little more about these complex organisms. One of the joys of iSpot is that observers can learn from experts IDs and comments on other people's postings.
