Abstract

During a survey of freshwater fungi in temperate southern Australia, two new taxa were found, Melanascoma panespora and Pleurothecium brunius. Morphological and molecular data place Melanascoma panespora in the Diaporthomycetidae representing a new genus. Melanascoma, along with Proliferophorum and Paraproliferophorum, form a new lineage and the family Melanascomaceae is introduced. Phylogenetic analyses using ITS, 28S, and 18S nrRNA gene sequences,, along with morphological examination revealed Pleurothecium brunius to be a new species of Pleurothecium, sister to P. aquaticum.

澳大利亚南部的淡水子囊菌：Melanascomaceae fam.

在对澳大利亚南部温带淡水真菌的调查中，发现了两个新的类群，即 Melanascoma panespora 和 Pleurothecium brunius。形态学和分子数据将 Melanascoma panespora 归入 Diaporthomycetidae，代表一个新属。Melanascoma 与 Proliferophorum 和 Paraproliferophorum 一起形成了一个新的品系，并引入了 Melanascomaceae 科。利用 ITS、28S 和 18S nrRNA 基因序列进行的系统发育分析以及形态学检查发现，Pleurothecium brunius 是 Pleurothecium 的一个新种，是 P. aquaticum 的姊妹。引用：Fryar SC, Catcheside DEA (2023).Fryar SC, Catcheside DEA (2023)：Melanascomaceae fam.Fungal Systematics and Evolution 11: 85-93. doi: 10.3114/fuse.2023.11.07.
