Identificación morfológica y molecular de miembros de la familia Hymenochaetaceae presentes en la sección Fungario del HUTPL

Abstract

Ecuador is a country with one of the highest rates of endemism and rarity in biological diversity, which is still poorly studied, especially the kingdom of fungi. It is known that certain species of Hymenochaetaceae have some potential beneficial properties, or even harmful to certain forests, making them a subject of ecological and economic interest that needs to be studied, so that in the future they can create management plans for parasitic species or discovered possible applications. From collections deposited in the herbarium Fungario HUTPL, from montane and dry in the southern region of Ecuador tropical forests, 22 samples were analyzed morphologically and molecularly considering the ITS-5.8S and partial LSU genes encoding ribosomal nuclear DNA. Morphological data suggest five genera Hymenochaete, Phellinus, Fuscoporia, Fulvifomes and Coltricia including eight species. Phylogenetic analysis found a strong correlation with morphological results for four clades = genres. Two species are confirmed morphologically-molecularly Hymenochaete damicornis and H. cf. subferruginea. Two species Fuscoporia aff. ferruginous, and Hymenochaete aff. They rubiginosa remain as related by their slight morphological differences.
