Remarks
|
|
Morphologically similar species include L. atlantica, L. humida, L. elobata and especially L. jackii, L. celata, L. toensbergiana, L. sylvicola, but these can be distinguished chemically, see the discussion under L. jackii. L. atlantica is chemically and morphologically rather similar to L. neojackii, which is described as containing both roccellic/angardianic and rangiformic acids at the same time but no atranorin. L. achariana is sometimes morphologically very similar but contains lecanoric acid.
