New records of Oleoguttula mirabilis and Rachicladosporium antarcticum from James Ross Island, Antarctica

Abstract

A group of seven isolates of black meristematic fungi was collected from rocks within the framework of mycological research focused on the study of diversity of rock-inhabiting fungi on James Ross Island in Antarctica. Their identification was based on ITS rDNA sequence comparisons supported by morphological data. Obtained results assigned four analysed strains as Oleoguttula mirabilis and three isolates as Rachicladosporium antarcticum. To the best of our knowledge this is the second report of isolation of these two psychrophilic species from different parts of James Ross Island which imply that they probably represent a common part of its environmental microbial flora.
