Abstract

Megasporoporia sensu lato is a common polypore genus in tropics, the members of which are readily recognized in the field because of their resupinate, light-coloured basidiocarps with big pores. The species of the genus usually grow on fresh fallen trunks and branches. The genus was recognized as polyphyletic by molecular analyses and divided into three genera: Megasporia, Megasporoporia sensu stricto and Megasporoporiella. In the present study, phylogenies based on the combined 2-gene (ITS + nLSU) and 4-gene (ITS + nLSU + mtSSU + TEF) sequences datasets of Megasporoporia sensu lato are analysed, and 21 lineages nested in three clades (the Megasporia clade, the Megasporoporia sensu stricto clade and the Megasporoporiella clade) are formed. Based on morphological examination, four new species, Megasporia bambusae, Megasporia fusiformis, Megasporoporia inflata and Megasporoporiella australiae, are described based on materials from Australia, China and Malaysia, and a new combination, Megasporoporiella hubeiensis comb. nov., is proposed. Megasporoporiella pseudocavernulosa is selected as the type species of Megasporoporiella because the previous type species Megasporoporiella cavernulosa was misidentified. Polyporus megasporoporus is the revised name for Megasporoporiella lacerata. In addition, a comparison of main characteristics and an identification key of Megasporoporia sensu lato are provided.

大孢子菌属4个新种的系统发育分析(多孢子目，担子菌科)

大孢子属(Megasporoporia sensu lato)是热带地区常见的多孢子属，其成员在野外很容易被识别，因为它们具有复生的、浅颜色的、气孔大的担子果。该属的物种通常生长在新鲜倒下的树干和树枝上。经分子分析，该属具有多系性，可分为大孢子虫属、大孢子虫属和大孢子虫属3属。本研究基于2基因(ITS + nLSU)和4基因(ITS + nLSU + mtSSU + TEF)组合序列数据集对大孢子虫的系统发育进行了分析，形成了3个分支(大孢子虫、狭义孢子虫和大孢子虫)的21个谱系。在形态学研究的基础上，根据澳大利亚、中国和马来西亚的资料，描述了竹大孢子虫(megasporporia bambusae)、fususiformis大孢子虫(megasporporia inflata)和澳大利亚大孢子虫(Megasporoporiella australiia) 4个新种和湖北大孢子虫梳状新组合。建议11月11日。由于之前的模式种海绵状巨孢孢子虫被误认，因此选择假海绵状巨孢孢子虫作为其模式种。大孢子虫是裂口大孢子虫的修订名称。此外，还对不同品种的主要性状进行了比较，并给出了鉴定关键字。
