Abstract

Abstract: In the course of surveys on dothideomycetous fungal genera associated with various hosts in Taiwan, Neomassaria-like species were collected as saprobes on dead stems of Rhododendron sp. Maximum likelihood and Bayesian phylogenetic analyses based on concatenated LSU, rpb2, SSU and tef1 gene matrices indicate that Neomassaria-like isolates generated in our study formed a separate clade in a sister group relationship with Neomassaria fabacearum with high statistical support. Hence, the new species Neomassaria formosana is described to accommodate the new linage in Neomassaria. The new species is characterised by immersed to erumpent, papillate ascomata with a dark brown peridium, fissitunicate, cylindrical to oblong asci and fusoid to ellipsoid, hyaline, bicellular ascospores with 4–6 large guttules. Moreover, Neomassaria formed a monophyletic and well-supported lineage with an uncertain phylogenetic placement within the Pleosporales. Therefore, the new family Neomassariaceae is proposed for the genus Neomassaria within the order Pleosporales, Dothideomycetes. The morphological characters also support justification for both the new family and the new species.

台湾真菌区系新增1:新麻麻科。11月。

摘要/ Abstract摘要:在对台湾地区不同寄主的齿形菌属真菌进行调查的过程中，在杜鹃花(Rhododendron sp.)的死茎上收集了Neomassaria-like种作为样本。基于LSU、rpb2、SSU和tef1基因序列的最大似然和贝叶斯系统发育分析表明，本研究中产生的Neomassaria-like菌株与新齿形菌(Neomassaria fabacearum)形成了一个独立的分支，具有较高的统计支持度。因此，新种台湾新马属的描述是为了适应新马属的新谱系。新种的特点是浸没到隆起，乳突状的子囊，有深棕色的囊膜，裂裂，圆柱形到长圆形的子囊，丝状到椭圆形的，透明的双细胞子囊孢子，有4-6个大的小管。此外，Neomassaria形成了一个单系且支持良好的谱系，其系统发育位置在多孢子门中不确定。因此，在多孢子目，多孢子菌目中，提出了新泻菌属新泻菌科。形态学特征也支持新科和新种的正当性。

期刊介绍： Cryptogamie is divided into three sections, each published as an individual publication: Cryptogamie, Bryologie, Cryptogamie, Algologie and Cryptogamie, Mycologie. Cryptogamie is a French journal of international scope publishing in several European languages. It accepts original papers and review articles on the systematics, biology and ecology of all cryptogams (algae; bryophytes; fungi and lichens, respectively).
