蘑菇目革状真菌的资源、分类与系统发育研究

现有分子系统学的研究表明蘑菇目中也包含了大量革状木材腐朽真菌的种类，该类真菌具有重要的生态功能和多种不同的进化起源。目前，关于他们的研究还非常匮乏：物种多样性不清楚；部分属种的分类地位还不确定；一些重要属属内和属间的系统发育关系尚不明确。本项目拟在全国范围内对蘑菇目革菌资源进行调查和标本采集，采用形态学和分子系统学相结合的方法对馆藏和新鲜采集的标本进行研究；发现蘑菇目革菌新的枝系，明确我国蘑菇目革菌的物种多样和分布，解决一些属种的分类地位，阐明几个重要属属内及其与近缘属之间的系统发育关系。研究结果将极大地丰富我国革菌的物种多样性；完善蘑菇目革菌的分类系统；并为蘑菇目系统的构建以及不同子实体形态和生态习性演化过程的研究提供证据。

The Agaricales has been demonstrated to include many corticioid fungi, which are ecologically important and have evolved for many times. However, so far, this group of fungi has been poorly studied. The species diversity is not clear, and taxonomic positions and phylogeny of some genera and species are still unresolved. In this project, intensive investigations and collections of corticioid fungi in Agaricales in different forest types all around China will be carried out. All these newly collected and herbaria deposited specimens will be carefully studied by using both morphological and molecular phylogenetic methods. The aims of this project are to: (1) find new phylogenetic lineages; (2) figure out the species diversity and distributions in China; (3) resolve the taxonomic positions of some genera and species; (4) clarify the inter- and intra-generic phylogenetic relationship of several importance genera. This project will significantly increase the species diversity, and complete the taxonomic systems of corticioid fungi in Agaricales. Meanwhile, the results can be used in the construction of the taxonomic systems of Agaricales and researches on evolutions of different fruiting bodies and life strategies.
