Biodiversity of Xylariaceae (Ascomycota) and their hosts in protected areas from Tucuman (Argentina)

Abstract

Fourty nine species belonging to the genera Astrocystis, Biscogniauxia, Daldinia, Entonaema, Hypoxylon, Kretzschmaria, Phylacia, Poronia, Rosellinia, Stilbohypoxylon and Xylaria were recorded in protected areas from Tucuman. The species are grouped in probably endemic, cosmopolitan, neotropical and pantropical. The biodiversity of Xylariaceae in this province is compared with those from other countries. Twenty-three host taxa are registered, most of them were dicots. Cinnamomum porphyrium and Podocarpus parlatorei were the two native hosts more colonized.Se registran cuarenta y nueve especies pertenecientes a los géneros Astrocystis, Biscogniauxia, Daldinia, Entonaema, Hypoxylon, Kretzschmaria, Phylacia, Poronia, Rosellinia, Stilbohypoxylon y Xylaria.

Se compara la biodiversidad de Xylariales de la provincia de Tucumán con la de otros países. Se identifican veintitrés hospedantes, la mayoría de ellos dicotiledóneas, siendo Cinnamomum porphyrium y Podocarpus parlatorei las especies nativas más colonizadas.
