Phylogenetic analyses and morphological examination confirmed two new species in the tropical polypore genus , and , from Australia and tropical Asia, respectively. A phylogenetic analysis based on the two DNA markers including the nuclear ribosomal internal transcribed spacer (ITS) region and the large subunit (nLSU) gene shows that these two new species form two independent lineages nested in the genus . is characterized by perennial and ungulate basidiomata, the occasional presence of hymenial setae, a trimitic hyphal structure in the context and a dimitic hyphal system in the trama, and broadly ellipsoid to subglobose basidiospores measuring 5.2-6 × 4-5 μm. is characterized by perennial and resupinate basidiomata with distinct receding margin, glancing pores, very thin to almost lacking subiculum, a dimitic hyphal structure, the absence of any setal elements, broadly ellipsoid to subglobose basidiospores measuring 3.8-4.9 × 3-4.2 µm. The differences among the new species and their phylogenetically related and morphologically similar species are discussed.
系统发育分析和形态学检查证实，在热带多孔菌属中分别发现了来自澳大利亚和热带亚洲的两个新物种，即 和 。基于包括核糖体内部转录间隔区（ITS）区域和大亚基（nLSU）基因在内的两个DNA标记进行的系统发育分析表明，这两个新物种形成了嵌套在该属中的两个独立谱系。 的特征是多年生有蹄状担子果，偶尔有子实层刚毛，菌肉中有三系菌丝结构，菌髓中有二系菌丝系统，以及宽椭圆形至近球形的担孢子，大小为5.2 - 6×4 - 5μm。 的特征是多年生平伏担子果，边缘明显后缩，孔口斜生，菌托非常薄至几乎没有，二系菌丝结构，没有任何刚毛状结构，宽椭圆形至近球形的担孢子，大小为3.8 - 4.9×3 - 4.2μm。讨论了新物种与其系统发育相关和形态相似物种之间的差异。
