Diversity of Polyporaceae fungi found in the Yasuní National Park in Ecuador.

Yasuni National Park (YNP) and the adjacent Huaorani Indian territory are located in the tropical jungle of Ecuador, covering 1.6 million ha, forming the largest protected area of the Ecuadorian Amazon region. It’s considered one of the most diverse places on Earth, with species richness maxima found for amphibians, birds, mammals and vascular plants, however, fungal diversity still remains unknown. A survey centered in the Polyporales fungal order was conducted in 2013 at the Yasuni Research Station of the Pontificia Universidad Catolica del Ecuador in a 50 ha permanent plot within the YNP. Six transects of 10x100m were surveyed. Here we present our results specifically of the Polyporaceae family, which was the most frequent during the survey, with 47 samples collected. Identification of samples was based on morphological characters and ITS sequence analysis. Sixteen different taxa were identified based on ITS sequence. Phylogenetic analysis based on ML showed 13 clades with high bootstrap support. Within the Trametes clade several subgroups could be identified. Most sequence alignments had no comparable hits on Blastn searches in GenBank (> 98% coverage, > 98% identity). In some occasions the closest hit on the search formed a separate clade in the phylogenetic tree. Three samples were identified based only on morphology. The results show a high diversity of Polyporaceae fungi in Yasuni, with several potential new species, and evidence the lack of publicly available genetic information for tropical polypores.
