is a genus of crustose lichens containing 13 accepted species that can be separated into two groups, based on differences in secondary chemistry that correlate with differences in characters of the sexual reproductive structures (asci and ascospores). Molecular phylogenetic analyses recovered these groups as monophyletic and support their recognition as distinct genera that differ in phenotypic characters. Species containing 2'--methylperlatolic acid are transferred to the new genus, Guzow-Krzem., Kukwa & Lendemer and four new combinations are proposed: (Lendemer) Guzow-Krzem., Kukwa & Lendemer, (Lendemer) Guzow-Krzem., Kukwa & Lendemer, (Guzow-Krzem., Łubek, Kubiak & Kukwa) Guzow-Krzem., Kukwa & Lendemer and (Lumbsch, A.W. Archer & Elix) Guzow-Krzem., Kukwa & Lendemer. The remaining species produce thamnolic acid and represent s.str. Haplotype analyses recovered sequences of in two distinct groups, one corresponding to s.str. and one to , the latter being resurrected from synonymy of and, thus, requiring the combination, (Erichsen) Ptach-Styn, Guzow-Krzem., Tønsberg & Kukwa. Sequences of were found to be intermixed within the otherwise monophyletic s.str. These two taxa, which differ in contrasting reproductive mode and overall geographic distributions, are maintained as distinct, pending further studies with additional molecular loci. Lectotypes are selected for , and P.chloropoliaf.cana. The latter is a synonym of . New primers for the amplification of mtSSU are also presented.
是一种壳状地衣属，包含13个公认的物种，根据次生化学差异可分为两组，这些差异与有性生殖结构（子囊和子囊孢子）的特征差异相关。分子系统发育分析表明这些组是单系的，并支持将它们识别为在表型特征上不同的独特属。含有2'-甲基珍珠酸的物种被转移到新属Guzow-Krzem.、Kukwa & Lendemer，并提出了四个新组合：(Lendemer) Guzow-Krzem.、Kukwa & Lendemer，(Lendemer) Guzow-Krzem.、Kukwa & Lendemer，(Guzow-Krzem.、Łubek、Kubiak & Kukwa) Guzow-Krzem.、Kukwa & Lendemer和(Lumbsch、A.W. Archer & Elix) Guzow-Krzem.、Kukwa & Lendemer。其余物种产生 thamnolic 酸，代表狭义的[该属名未给出]。单倍型分析在两个不同的组中恢复了[该属名未给出]的序列，一组对应狭义的[该属名未给出]，另一组对应[该属名未给出]，后者从[该属名未给出]的同义名中复活，因此需要组合(Erichsen) Ptach-Styn、Guzow-Krzem.、Tønsberg & Kukwa。发现[该属名未给出]的序列在其他方面单系的狭义[该属名未给出]中混合在一起。这两个分类单元在生殖模式和总体地理分布上形成对比，在使用额外分子位点进行进一步研究之前，仍保持为不同的分类单元。为[该属名未给出]、[该属名未给出]和P.chloropoliaf.cana选择了选型模式。后者是[该属名未给出]的同义名。还提出了用于扩增线粒体小亚基（mtSSU）的新引物。
