Four species are added to Phylloporia. Three species, originating from the western edge of the Guineo-Congolian rainforest in Gabon (central Africa), are described as new. Phylloporia afrospathulata sp. nov. forms seasonal, stipitate, solitary basidiomata emerging from soil, more likely connected to buried roots, and has broadly ellipsoid basidiospores. Phylloporia inonotoides sp. nov. forms seasonal sessile, soft basidiomata, solitary at the base of small-stemmed trees including Crotonogyne manniana (Euphorbiaceae) and Garcinia cf. smeathmannii (Clusiaceae). It has a homogeneous context, large pores (2-3 mm), and oblong-ellipsoid to suballantoid basidiospores. Phylloporia fulva sp. nov. forms sessile, conchate, mostly pendant, gregarious basidiomata emerging from the trunk of an unidentified small-stemmed tree and has small, subglobose basidiospores. This species is compared to Polyporus pullus and Phylloporia pulla comb. nov. and proposed based on the study of the type specimen. Phylogenetic inferences using partial nuc 28S DNA sequence data (region including the D1/D2/D3 domains) and the most exhaustive dataset available to date resolved these new morphospecies as three distinct terminal lineages. No sequence data of P. pulla currently is available. The 28S-based phylogenic inferences poorly resolved the interspecific relationships within the Phylloporia clade.

Fomitiporia in sub-Saharan Africa: morphology and multigene phylogenetic analysis support three new species from the Guineo-Congolian rainforest.

Mycologia 2010 Nov-Dec;102(6):1303-17. Epub 2010 May 26.

Mycothèque de l'Université Catholique de Louvain (MUCL, BCCM™), Earth and Life Institute Mycology, Université Catholique de Louvain, Croix du Sud 3, B-1348 Louvain-la-Neuve, Belgium.

Fomitiporia nobilissima sp. nov., F. gabonensis sp. nov. and F. ivindoensis sp. nov., three species from the rainforest of the Guineo-Congolian phytogeographic region in Gabon, are described and illustrated. These species share a pileate basidiome, small basidiospores and an absence of setae. The critical morphological features that differentiate them are the pileus habit or shape, pore surface color, pore diameter and possibly ecology. Each new species forms distinct but closely related clades in phylogenetic analysis of DNA sequences from nuclear ribosomal LSU, ITS and translation elongation factor 1-α. Other species in sub-Saharan Africa are discussed briefly. A key to six species of Fomitiporia from sub-Saharan Africa is provided. The new combination Fomitiporia apiahyna is proposed.
