Species Concept and Molecular Phylogeny of West African Resuninate Thelephorales
Final Report Abstract
Thelephorales represent a cosmopolitan monophyletic fungal group within the Agaricomycetes (Basidiomycota, Fungi). Although public database INSD and UNITE have been particularly enriched with an impressive number of ITS rDNA thelephoroid sequences, patterns of species concept and lower-level phylogenetics within Thelephorales still remain unresolved. The high percentage of thelephoroid sequences generated from unnamed samples in contrast to the low availability of fruit body-based sequences and geographic bias (toward temperate Europe and America) raise up questions regarding sampling effort for a clear anatomical and phylogenetic species delimitation. To better understand morphological and phylogenetic species concept within Thelephorales, we suggested hereby a broadly sampled phylogenetic and detailed anatomy of fruit bodies. Our aim was to enlarge geographic sampled and the phylogenetic dataset with samples from the northern Guinean seasonal forests of West Africa. The ITS rDNA gene for the lower level phylogenetic relationship and the D1/D2 region of the LSU rDNA for the genus level were selected for evolutionary analyses. We sampled a total of 20 thelephoroid specimen and 325 specimens of other taxa from 5 West African countries (Benin, Burkina Faso, Mali, Guinea, Togo) during a total of 6 weeks. We faced two major constraints during the collecting trips. First, the climatic condition were not the best to sampling mycorrhizal fungi, and secondly we were not able to transport the specimens to Germany because of the lack of written document in regard to Nagoya protocol. However, we were able to investigate on specimens of any taxa we sampled during previous trips to generate papers and one LSc thesis on Thelephoroid taxa from guinea (West Africa). We thus contributed a lot to the taxonomical and ecological documentation of macromycètes from West Africa.
