Abstract

Phylogenetic analyses of a combined DNA data matrix containing nuclear small and large subunits (nSSU, nLSU) and mitochondrial small subunit (mtSSU) ribosomal RNA and the largest and second largest subunits of the RNA polymerase II (rpb1, rpb2) of representative Pezizomycotina revealed that the enigmatic genera Xylobotryum and Cirrosporium form an isolated, highly supported phylogenetic lineage within Leotiomyceta. Acknowledging their morphological and phylogenetic distinctness, we describe the new class Xylobotryomycetes, containing the new order Xylobotryales with the two new families Xylobotryaceae and Cirrosporiaceae. The two currently accepted species of Xylobotryum, X. andinum and X. portentosum, are described and illustrated by light and scanning electron microscopy. The generic type species X. andinum is epitypified with a recent collection for which a culture and sequence data are available. Acknowledging the phylogenetic distinctness of Candelariomycetidae from Lecanoromycetes revealed in previous and the current phylogenetic analyses, the new class Candelariomycetes is proposed.

子囊菌门的两个新分类：木霉菌目和Candelariomycetes。

对包含核小亚基和大亚基（nSSU，nLSU）和线粒体小亚基（mtSSU）核糖体RNA以及代表性的皮霉菌门的RNA聚合酶II的最大亚基和第二大亚基的组合DNA数据矩阵的系统发育分析显示，神秘的木霉属和环孢菌属形成分离的，Leotiomyceta内高度支持的系统发育谱系。认识到它们在形态和系统发育上的独特性，我们描述了新的木霉纲，包括木霉目和两个新的科木霉科和环孢菌科。光镜和扫描电子显微镜描述并说明了目前公认的两种Xylobotryum，X.andinum和X.portentosum。属型物种X.andinum是最近的一个集合的表型，其培养物和序列数据是可用的。认识到Candelariomyceteae与Lecanoromycetes在以前和现在的系统发育分析中所揭示的系统发育差异，提出了新的Candelariomoycetes纲。

期刊介绍： Persoonia aspires to publish papers focusing on the molecular systematics and evolution of fungi. Additionally, it seeks to advance fungal taxonomy by employing a polythetic approach to elucidate the genuine phylogeny and relationships within the kingdom Fungi. The journal is dedicated to disseminating high-quality papers that unravel both known and novel fungal taxa at the DNA level. Moreover, it endeavors to provide fresh insights into evolutionary processes and relationships. The scope of papers considered encompasses research articles, along with topical and book reviews.
