Abstract

We are studying microfungi growing on Poaceae hosts in different geographical regions and in this study we introduce Kwanghwana miscanthi Karun., C.H.Kuo & K.D.Hyde, gen. et sp. nov., based on phylogenetic analyses of DNA sequences of four loci used in combination (three ribosomal (LSU, SSU and ITS) and one protein coding region (TEF1-α)) and on morphological characters. This new genus, including a single species isolated from Miscanthus floridulus (Labill.) Warb. ex K.Schum. & Lauterb., is molecularly distinct from closely related genera, Neostagonosporella C.L.Yang, X.L.Xu & K.D.Hyde, Setophoma Gruyter, Aveskamp & Verkley and Edenia M.C.Gonzalez, A.L.Anaya, Glenn, Saucedo & Hanlin. Kwanghwana miscanthi Karun., C.H.Kuo & K.D.Hyde, sp. nov., also differs from Neostagonosporella and Setophoma by having subglobose ascomata, irregularly thickened peridium, cellular, septate and branched pseudoparaphyses, and fusiform, broadly fusoid, 3-septate ascospores.

我们对不同地理区域禾本科寄主上生长的微真菌进行了研究，并引种了kwanghwa miscanthi Karun。基于对3个核糖体(LSU, SSU和ITS)和1个蛋白质编码区(TEF1-α)) 4个基因座组合使用的DNA序列和形态学特征的系统发育分析。本新属，包括从芒草(唇形)中分离的一种。卑鄙的人。K.Schum交货。& Lauterb。在分子上不同于密切相关的属Neostagonosporella C.L.Yang, X.L.Xu & k.d.h ided, Setophoma Gruyter, Aveskamp & Verkley和Edenia m.c.a zgonzalez, a.l.a anaya, Glenn, Saucedo & Hanlin。kwanghwa miscanthi Karun。与Neostagonosporella和Setophoma的不同之处还在于，其子囊孢子呈亚球状，囊膜不规则增厚，胞状、隔状和支状假性麻痹，以及梭状、宽梭状、3隔的子囊孢子。

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).
