Abstract :
[en] Phylloporia (Hymenochaetaceae) is becoming a very large and complex genus and the species definition is becoming a challenge, as for many other groups of Hymenochaetaceae. Phylloporia comprises 79 species up to date. However, this number is probably still largely underestimated. A comprehensive, multigene phylogeny of Phylloporia (Hymenochaetaceae, Basidiomycota), inferred from the large subunit nuclear ribosomal region (LSU), portions of the translation elongation factor 1-α (TEF-1α), and second largest subunit of RNA polymerase II (RPB2) genes is presented and discussed. The multigene phylogeny reveals several undescribed paleotropical or neotropical phylogenetic species. On this basis, complemented by both morphological and ecological data, six new species from tropical Africa are described: P. afropectinata, P. cinnamomea, P. memecyli, P. miomboensis, P. pseudoweberiana, and P. warneckeicola. A new combination, P. microspora (basionym Inonotus microsporus), is also proposed. A synthesis of the taxonomic and ecological knowledge of Phylloporia in tropical Africa is presented, with an identification key for the African species known to date. Although the multigene phylogenetic inferences do not resolve the backbone structure within Phylloporia, it reveals two main lineages, a basal A and a core B lineage. The basal lineage contains six species whereas the core lineage comprises most of the described species and a number of unnamed taxa. The multigene phylogenetic inferences also resolved several well-supported, multiple species lineages within the core lineage. These lineages are predominantly biogeographically structured with a dichotomy Neotropics vs Paleotropics. They are discussed in relation to the morpho-ecological types.

Commentary :
This work was supported by a grant to M. Jerusalem (grant no. 34226436) from the Belgian Industrial and Agricultural Research Funds (FRIA, FNRS). Matthieu Jerusalem and Prudence Yombiyeni gratefully acknowledge the support received from the Research Institute in Tropical Ecology (IRET). Our gratitude is also extended to Anna Feistner, Director Gabon Biodiversity Program, Gauthier Moussavou and Landry Tchignoumba (Gabon Biodiversity Program, a partnership between the Smithsonian Conservation Biology Institute, Assala Gabon, and the Government of Gabon) for facilitating the field work at the CTFS-ForestGEO Rabi plot in Gabon. The authors also extend their gratitude to the Kenyan Wildlife Service for granting permission to collect at Mount Elgon National Park, to J. Matasyoh, from Egerton University, Kenya, and and the staff at Mount Elgon National Park, particularly Bonface Masai, for his invaluable help during field work. Cony Decock gratefully acknowledges the financial support received from the Belgian State – Belgian Federal Science Policy, through the BCCM program, and from the FNRS through the ERAFRICA project ASAFEM. Thanks also are extended to Stéphanie Huret (MUCL) for her help with the sequencing program. Cony Decock also gratefully thanks Leif Ryvarden for the loan of a specimen of P. cinnamomea from Cameroon and of P. miomboensis from Zimbabwe, and for continual support over the years. Mario Amalfi gratefully thanks the FNRS for the financial support for his field trip in Gabon (SEJOUR_V3 40018241).
