found on an old stone wall in woodland in northern snowdonia
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
thanks for your ID (and of the many others)!
we have several disused iron/lead mine workings around here - would that influence the types of lichen found ?(as in would the iron in the substrate encourage the L. lithophila to develope?)
A substantial number of lichens, including many rarities show preference or requirement for old mine sites - especially lead and other non-ferrous metals.
It is in fact a major problem for lichenology that tidying of such sites, including old spoil heaps, is causing significant losses of species.
Lecidea lithophila is not so fussy - it seems simply to require base-poor rocks, but it shows a much greater tendency than most accompanying species to deposit iron-oxide on its surface. I don't think it has an extra iron requirement, nor can the orange colour itself be considered diagnostic. Quite a number of lichens can develop patchy, orange, iron-oxide-discolouration, apart from those that are always yellow or orange.
thanks so much for the info
