Abstract
We studied a number of sub-Saharan collections of corticioid Xylodon and Lyomyces species, including several types. Morphological descriptions and molecular analyses based on the ribosomal DNA loci nuc rDNA ITS1-5.8S-ITS2 and when possible nuc 28S rDNA, allow us to introduce four new species: L. densiusculus , X. angustisporus , X. dissiliens , and X. laxiusculus . DNA barcodes for X. submucronatus and X. pruniaceus are published for the first time and X. pruniaceus is re-described.
