A new species of Synarthonia, S. leproidica, is described from Luxembourg. Phylogenetic analyses of mtSSU and RPB2 sequences were used to determine the generic affiliation of this sterile species. Synarthonia leproidica differs from all other species of the genus by the combination of a leproid thallus and the production of psoromic acid. It is the sister species to S. muriformis in our phylogenetic analyses. The discovery of the new species suggests that other strictly sorediate lichen species might have been overlooked in Europe, even in intensely explored countries such as Luxembourg. Phylogenetic analyses further confirm the placement of Reichlingia anombrophila in the genus Reichlingia and of Synarthonia astroidestera in the genus Synarthonia. Arthonia atlantica is transferred to the genus Reichlingia as R. dendritica.

来自卢森堡的 Synarthonia 新种和 Reichlingia (Arthoniaceae) 属的新组合

一种新的物种合奏曲,S. leproidica, 描述自卢森堡。mtSSU 的系统发育分析和RPB2个序列用于确定该不育物种的属属关系。麻花合欢与该属的所有其他物种的不同之处在于，它结合了麻风菌体和产生的补脂酸。它是姐妹物种鼠形链球菌在我们的系统发育分析中。新物种的发现表明，在欧洲，甚至在卢森堡等被深入探索的国家，其他严格意义上的地衣物种可能被忽视了。系统发育分析进一步证实了无花毛茛在该属灵芝和天竺葵在该属合奏曲.大西洋野花被转移到该属灵芝作为R.树突.
