Abstract
Fungi were isolated from fellfield soils at Signy Island (60° 43′ S, 45° 38′ W) in the maritime Antarctic between December 1994 and February 1995 in order to study their role in colonization processes. A psychrophilic species of Humicola was isolated that differs physiologically and morphologically from Humicola fuscoatra, to which it bears a resemblance. Based on these characteristics it is described herein as a new species, Humicola marvinii.
