ABSTRACT

Marine fungi ascribed to the ascomycetes and the hyphomycetes are infrequently reported for the Southern Ocean. For this reason, the main objective of the present work was to detect the presence of these fungi seawater of Potter Cove, King George (25 de Mayo) Island, South Shetland Island, Antarctica. For this purpose marine fungi were grown on wood test panels, placed into plastic nets in the tidal zone, exposed to the Antarctic seawater for different periods of time, which ranged between 2 and 12 months.As a result of this survey, we were able to recover and identify two marine fungi, Papulospora halima (which represents the first report for this environment) and a new morphological variety of Halosphaeria tubulifera.


Los ascomicetes e hifomicetes marinos están escasamente documentados para el océano Atlántico Sur. Por este motivo, el principal objetivo del presente trabajo fue detectar la presencia de dichos hongos en las agua marinas de la Potter Cove, en la isla Rey Jorge/25 de Mayo (islas Shetland del Sur, Antártida). Para este propósito, los hongos marinos se desarrollaron en paneles de madera dentro de una red plástica en la zona tidal, expuestos al agua de mar antártica por diferentes períodos de tiempo que oscilaron entre 2 a 12 meses. Como resultado de este estudio, fuimos capaces de recuperar e identificar 2 hongos marinos, Papulospora halima (que representa el primer reporte para este ambiente) y una nueva variedad morfológica de Halosphaeria tubulifera.
