最近在中国和南美进行了大量研究,代表四个属的四个独立进化枝已经被系统发育识别。在这项研究中,更多样品,主要来自亚热带和热带亚洲,大洋洲,东非,被分析。基于4个基因的序列数据集(ITSnLSUmtSSUtef)的系统发育已证实在巨大的细菌中存在四个属:Jorgewright,Mariorajchenbergia,Megasporia,和特加索波罗尼亚。六个新物种,JorgewrightAustroasiana,Jorgewrigtia非路人,JorgewrightTenuis,Mariorajchenbergiasubleuplaca,食草大虫,和巨大孢子虫,基于形态学和系统发育分析进行了描述。提出了三种新的组合,viz.Jorgewrightkirkii,Mariorajchenbergiaepitephra,和Mariorajchenbergialeucoplaca。迄今为止,接受了36种大孔菌,并提供了这些物种的鉴定钥匙。此外,亚马逊Dichomus的鉴定,柱状孢菌,并讨论了六孔大孔菌。
Megasporoporia sensu lato has recently been intensively studied in
China and South America, and four independent clades representing four genera have been recognized phylogenetically. In this study, more samples, mostly from subtropical and tropical Asia, Oceania, and East Africa, are analyzed. A phylogeny based on a 4-gene dataset of sequences (ITS + nLSU + mtSSU + tef) has confirmed the presence of four genera in Megasporoporia sensu lato: Jorgewrightia, Mariorajchenbergia, Megasporia, and Megasporoporia sensu stricto. Six new species, Jorgewrightia austroasiana, Jorgewrightia irregularis, Jorgewrightia tenuis, Mariorajchenbergia subleucoplaca, Megasporia olivacea, and Megasporia sinuosa, are described based on morphology and phylogenetic analysis. Three new combinations are proposed, viz. Jorgewrightia kirkii, Mariorajchenbergia epitephra, and Mariorajchenbergia leucoplaca. To date, 36 species of Megasporoporia sensu lato are accepted and an identification key to these species is provided. In addition, the identification of Dichomitus amazonicus, Dichomitus cylindrosporus, and Megasporoporia hexagonoides is discussed.
