摘要

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.
