Caracterización morfo-molecular del complejo Oudemansiella platensis-canarii en el sur del Ecuador

Abstract

Some species of the genus Oudemansiella (Physalacriaceae, Basidiomycota) have been reclassified lately because of the similarity of their basidiomata, the complexity of its micromorphology and lack of molecular data that contribute to their classification systematic. In this paper we review 12 specimens of complex Oudemansiella platensis-canarii collected in southern Ecuador with the aim of proposing the best method for taxonomic identification. The specimens were compared with Macroscopic photographs and illustrations Micromorphological type organisms in the literature reviewed. region sequences ITS-5.8S + partial LSU obtained ADNrn from the basidiomata collected in Ecuador and compared by analysis Phylogenetic with similar sequences available in databases. Structure pileipellis was the Micromorphological feature that contributed more taxonomic value, presenting distinctive features between these two species. Multigene phylogenetic analysis allowed molecularly define the species examined within this complex. The Morphological and phylogenetic correlation allowed us to identify the species Oudemansiella platensis and Oudemansiella aff. canarii, the latter being a new record for Ecuador
