is a remarkable group of polypore fungi, mainly characterized by particular double-walled basidiospores with a coloured endosporium ornamented with columns or crests, and a hyaline smooth exosporium. In order to establish an integrative morphological and molecular phylogenetic approach to clarify relationship of Neotropical s.lat. within the family, morphological analyses, including scanning electron microscopy, as well as a molecular phylogenetic approach based on one (ITS) and four loci (ITS-5.8S, LSU, TEF-1α and ), were carried out. Ultrastructural analyses raised up a new character for systematics, i.e, the presence of perforation in the exosporium with holes that are connected with hollow columns of the endosporium. This character is considered as a synapomorphy in , a new genus proposed here to accommodate (≡ ). is proposed to accommodate species with monomitic context: and . Molecular phylogenetic analyses confirm that both genera grouped as strongly supported distinct lineages out of the s.str. clade.
是一组显著的多孔菌,主要特征是具有特殊的双壁担孢子,其有色的内生孢子具柱状或嵴状纹饰,外生孢子透明光滑。为了建立一种综合形态学和分子系统发育方法来阐明新热带地区广义的该属在该科内的关系,进行了形态学分析,包括扫描电子显微镜观察,以及基于一个位点(ITS)和四个基因座(ITS - 5.8S、LSU、TEF - 1α和[此处原文缺失一个基因座信息])的分子系统发育方法。超微结构分析为该属的系统学提出了一个新特征,即外生孢子上存在穿孔,这些孔与内生孢子的中空柱相连。这一特征被视为该属的一个共衍征,这里提出一个新属来容纳[此处原文缺失相关物种信息](≡[此处原文缺失相关物种信息])。提出该属来容纳具有单系组织的物种:[此处原文缺失相关物种信息]和[此处原文缺失相关物种信息]。分子系统发育分析证实,这两个属在狭义的该属分支之外聚为两个得到有力支持的不同分支。
