Résumé :

Fulvifomes is a genus of Hymenochaetaceae polypore fungi whose taxonomy remainsincomplete and is still debated. In this master’s thesis, we propose a newphylogenetic tree for the genus, constructed by analyzing 41 samples of fungi storedat MUCL (Mycotheque de l’Universite Catholique de Louvain), and using four genes:ITS, nucLSU, Tef1 alpha and rpb2. In addition, molecular analysis was conducted ontwo new samples of fungi originating from Cameroon and the Democratic Republic ofCongo. After performing molecular analysis comprising DNA extraction, geneamplification and sequencing, a morphological and biogeographical review of thegenus was conducted in order to search for characteristics that may delimit theconcept of species within the genus. We have attempted to define the names ofpreviously unknown Fulvifomes sp. sequences from Genbank, of the 41 samples fromMUCL, and have proposed recombinations for species which had been placed inseparate genera. Five new species have been identified and further studies toestablish full descriptions will serve to enrich the database of Fulvifomes. Inconclusion, the phylogenetic tree proposed is the most complete and up to date of thegenus Fulvifomes, which not only serves as a robust basis for future studies but alsoallows for hypotheses on the evolution of the genus.
