Revision of the taxonomic status of the genus Gloeoporus (Polyporales, Basidiomycota) reveals two new species
Gloeoporus Mont. is characterized by an easily separated gelatinous hymenophore and a continuous hymenium over the pore mouth. Recent molecular taxonomic and phylogenetic research showed that morphological grouping of Gloeoporus is polyphyletic. The lack of comprehensive phylogenetic studies of Gloeoporus exacerbates confusion in determining the taxonomic position of the genus. To delimit the genus Gloeoporus, we performed multi-locus phylogenetic analysis using the internal transcribed spacer (ITS) region, the nuclear large subunit ribosomal DNA (LSU), and the second-largest subunit of RNA polymerase II (rpb2). The phylogenetic analyses revealed that current delimitation of Gloeoporus is not monophyletic. Gloeoporus s.s. includes mostly clamped species lacking cystidia. Some species of Gloeoporus featuring simple septa and cystidia are proposed to be renamed to Meruliopsis. Two new species of Gloeoporus were also observed and they are named Gloeoporus africanus and Gloeoporus orientalis.
