saying that it is r. oederi for sure. It was a possibility. However, after I have searched about your suggestions which I thank, my opinion remains the same. The description of the apothecia in R. oederi “initially concave but disc becoming domed, with minute, raised folds (gyrose)” seems to fit perfectly (of course it is just my humble opinion) as I see there the concave, the domed and the raised folds, but still it could be anything else. So, opinions and votes are always welcome. the closest suggestion was, for me, the T. atrata but apothecia is not sunken on thallus.
“iron lover lichens”, as you call them, ranging from foliose to crustose. In the case of crustose lichens, known examples are:
Lecidea lithophila, L. lapicida, L. silacea
Porpidia favicunda, P. macrocarpa, and others that I can not remember now
Rhizocarpon oederi, R. copelandii,
Maybe with the exception of the first and the last, potentially any of them could grow on iron.
besides the rust tallus, this lichen is on a iron piece, and this Rhizocarpon is a iron lover.
