This contribution provides a synopsis of the presentations and discussions during the SIG session on cryptic speciation in lichen-forming fungi held during IMC9. In several cases, a re-examination of morphology against the background of molecular phylogenetic evidence revealed, sometimes subtle, morphological and/or chemical characters, supporting the distinction of particular clades at species level. However, there are also examples of cryptic species in which no morphological characters could be identified to distinguish between lineages. Several cases were presented in which distinct lineages are correlated with biogeographical patterns. When and how to name cryptic species was debated, and the use of terms such as "complex" or "aggregate" commended where the taxa formed part of a single lineage.
本贡献概述了 IMC9 期间举行的真菌形成地衣隐种专题研讨会上的演讲和讨论。在几种情况下,根据分子系统发育证据重新检查形态学,揭示了一些微妙的形态和/或化学特征,支持在种水平上区分特定的进化枝。然而,也有一些隐种的例子,其中没有可以识别的形态特征来区分谱系。还介绍了几个明显的谱系与生物地理模式相关的例子。何时以及如何命名隐种是有争议的,在分类群形成单一谱系的情况下,建议使用“复杂”或“聚合”等术语。
