基于日本、美国夏威夷州和德克萨斯州不同棕榈寄主采集的材料，研究了四种代表性内萼类群在物种和品种水平上的系统发育亲缘关系。它们包括属于E.的标本及其分离株。辛克图斯，E.毛被，E. melanoxanthusvar.grossus 和 E。 melanoxanthusvar.melanoxanthus。核核糖体 DNA 序列数据 (ITS-LSU nrDNA) 的系统发育分析证实，Endocalyx 属于 Xylariales (Sordariomycetes)，其中所有处理的物种和变种在 Cainiaceae 科内形成强有力的单系谱系。它们在系统发育上也得到了很好的解决，并且与其形态和生态范围一致。提议E的物种地位。 melanoxanthusvar.grossus 的名称为 E。格鲁苏科姆。等统计数据。十一月基于其独特的形态、分子、文化和生态特征。考虑到所有处理的物种都聚集在遥远的菜虫科 (Xylariales) 内，基于基底分生孢子梗的存在，内萼在 Apiosporaceae (Amphisphaeriales) 科 (Amphisphaeriales) 中的假定位置被拒绝。分生孢子梗伸长的这种特征模式被确定为在远缘相关的子囊菌谱系中独立进化的。对基于新分离株的内萼类群新的形态和培养特征进行了描述和评论。最近描述的E. Metroxyliis 简化为 E 的同义词。黑黄花。
The phylogenetic affinities of four representativeEndocalyxtaxa at the species and variety levels are studied based on materials collected on different palm hosts in Japan and the states of Hawaii and Texas, USA. They include specimens and their isolates belonging toE. cinctus,E. indumentum,E. melanoxanthusvar.grossus, andE. melanoxanthusvar.melanoxanthus. Phylogenetic analyses of nuclear ribosomal DNA sequence data (ITS-LSU nrDNA) confirmed thatEndocalyxbelongs to the order Xylariales (Sordariomycetes) where all species and varieties treated form a strongly supported monophyletic lineage within the family Cainiaceae. They were also phylogenetically well resolved and consistent with their morphological and ecological circumscription. Species status is proposed forE. melanoxanthusvar.grossusunder the nameE. grossuscomb. et stat. nov. on the basis of its distinct morphological, molecular, cultural, and ecological characteristics. The putative placement ofEndocalyxwithin the family Apiosporaceae (Amphisphaeriales), based on the presence of basauxic conidiophores, is rejected considering that all species treated clustered within the distant Cainiaceae (Xylariales). This characteristic mode of conidiophore elongation is determined to have evolved independently within distantly related ascomycetous lineages. Novel morphological and cultural features ofEndocalyxtaxa based on new isolates are described and commented. The recently describedE. metroxyliis reduced to a synonym withE. melanoxanthus.
