Jerusalem, M., Yombiyeni, P., Castillo, G. and Decock, C. (2019) “Hymenochaetaceae (Basidiomycota, Hymenochaetales) from the Guineo-Congolian phytochorion: Phylloporia rinoreae sp. nov., an additional undescribed species from the Forest Global Earth Observatory Plot in Gabon”, Plant Ecology and Evolution, 152(3), pp. 531-538. doi: 10.5091/plecevo.2019.1567.


Background and aims – The aim of this study is the continuation of an ongoing survey of Hymenochaetaceae (Basidiomycota, Hymenochaetales) from the lower Guinean sub-region in Central Africa. In this frame, a new species of Phylloporia is described from Gabon, based on morphological, ecological and phylogenetic data.
Methods – The species is described using morphological methods, and ecological data. DNA-based phylogenetic analysis are also used to search for affinities.
Key results – A new species of Phylloporia, P. rinoreae, is described based on specimens collected on living twigs of a shrubby Rinorea species (Violaceae), occurring in the Guineo-Congolian rain forest. Phylogenetic inferences using DNA sequence data from partial nuc 28S (region including the D1/D2/D3 domains) resolved this species as a distinct clade within the Phylloporia lineage. An identification key to the species reported from the Guineo-Congolian phytochorion is provided.
ConclusionPhylloporia rinoreae is the seventh species of the genus described from and so far only known from Gabon in the Lower Guinean phytogeographical sub-region.
