| 摘 要： | 本文基于核糖体SSU rDNA序列对石耳科Umbilicariaceae的系统地位进行了研究.将所获得的石耳科地衣中6个种的SSU rDNA序列与GenBank中其它地衣型及非地衣型真菌的相关序列进行比对用于系统发育研究.结果表明长期以来系统地位不够明确而暂时被置于茶渍目Lecanorales的石耳科不能被包括在茶渍目中,分子数据支持成立石耳目Umbilicariales.基于分子数据并结合形态学和解剖学特征描述了新目Umbilicariales J.C. Wei ＆ Q.M. Zhou（Lecanoromycetes,Ascomycota）.

| Abstract: | The phylogenetic position of the lichen family Umbilicariaceae is investigated using nucleotide sequences of the nuclear SSU rDNA region. Sequences of 6 species were obtained in this study and aligned to those of other lichenized and non-lichenized fungal species from GenBank. The result indicates that the Umbilicariaceae cannot be included in the order Lecanorales and the order Umbilicariales is supported by both the molecular and morphological data. The new order Umbilicariales within Lecanoromycetes, Ascomycota is described in this paper accordingly. |
