Lecanora s. lat. is a genus of crustose, rarely placodioid lichens comprising c. 1000 recognized species and subdivided into several morphology-based groups. Some of these groups have been supported in phylogenetic analyses and segregated as new genera. One of the remaining groups that has not been previously studied by molecular methods in much detail, the L. saligna-group, includes corticolous and lignicolous crustose lichens, usually containing isousnic or usnic acid (or both) as major secondary metabolites. As part of our ongoing project ‘Lecanomics’, a phylogenetic analysis based on two loci was conducted and found the L. saligna-group to be divided into two main clades and several well-supported minor clades. The L. varia clade, chosen as one of the outgroups, emerged within the L. saligna-group. The majority of the clades are characterized by phenotypic differences. However, several well-supported clades share similarities with their sister groups, suggesting that species circumscriptions based solely on phenotypic characters may be too conservative to characterize the true species diversity present within the group. Also, there is evidence for some geographical separation of lineages; for example, most North American individuals, previously known as Lecanora saligna and L. albellula, form two clades separate from their European namesakes and are here preliminarily called ‘Lecanora sp. B’, ‘Lecanora sp. C’ and ‘Lecanora sp. D’. However, L. saligna and L. albellula also appear to occur in North America, and some specimens from the Caucasus and Iran cluster within the North American clades. Lecanora anopta and L. subravida are reported for the first time from Iran.

Lecanora saligna 群的初步系统发育，附有物种划界的注释

勒卡诺拉s。纬度 是一种硬壳类，很少有扁形地衣，包括C. 1000 个已识别的物种，并细分为几个基于形态的组。其中一些组已在系统发育分析中得到支持，并被分离为新属。以前没有通过分子方法详细研究过的其余组之一，L. saligna-组，包括皮质地衣和木质地衣，通常含有异松香酸或松萝酸（或两者）作为主要的次生代谢物。作为我们正在进行的项目“Lecanomics”的一部分，进行了基于两个基因座的系统发育分析，发现L. saligna-组被分为两个主要进化枝和几个支持良好的次要进化枝。这L. varia进化枝，被选为外群之一，出现在L. saligna-团体。大多数进化枝的特征在于表型差异。然而，几个得到良好支持的进化枝与其姐妹群体有相似之处，这表明仅基于表型特征的物种限制可能过于保守，无法表征该群体中存在的真正物种多样性。此外，有证据表明世系在地理上有所分离；例如，大多数北美人，以前称为Lecanora saligna和L. albellula, 形成两个与欧洲同名不同的进化枝，在这里初步称为 '勒卡诺拉sp。乙','勒卡诺拉sp。C' 和 '勒卡诺拉sp。D'。然而，L. saligna和L. albellula似乎也出现在北美，一些来自高加索和伊朗的标本聚集在北美的进化枝中。Lecanora anopta和L. subravida伊朗首次报道。
