Catálogo de las colecciones de líquenes de la región de Magallanes y Antártica Chilena depositadas en el herbario del Instituto de la Patagonia (HIP)

Abstract

The lichen mycobiota of Magellan region is diverse but has been poorly studied. This situation can result in a low rating for this biodiversity and an inadequate management for the conservation of this group. A preliminary catalog of the lichen mycobiota of the Magallanes and Chilean Antarctic region was prepared from records deposited in the Herbarium of the Instituto de la Patagonia (HIP). The catalog includes information on habitat, collection locations, distribution in Chile, global distribution and record numbers of the 296 exsiccata examined. Taxonomical, geographical and ecological information is described for 100 taxa distributed in 3 classes, 9 orders, 19 families and 43 genera. The most diverse taxonomic orders were Lecanorales (Lecanoromycetes) with 24 genera and 51 taxa, and Peltigerales (Lecanoromycetes) with 9 genera and 37 taxa. These species represent collections made through a wide geographical and ecological range including four provincial districts (Magallanes, Tierra del Fuego, Última Esperanza and Chilean Antarctic), and ecosystems like steppes, shrubs, forests and Andean habitats. This information can contribute to improve and systematize the current knowledge of the lichen mycobiota of the southernmost region in Chile for management and conservation purposes.
