From the abstract of the referenced paper:
The fungal floras of plant communities and mineral soils were determined at locations both close to and away from sites of human activity. Petroleum contaminated soils and discarded wood which occur near Stations were also studied, the former or ... bacterial as well as fungal colonisation. The fungal floras of uncontaminated natural communities comprised relatively few species, Geomyces pannorum, Phoma herbarum and Thelebolus microsporus being the most common, together with Epicoccum nigrum at Mawson. P. herbarum dominated the fungal floras of mosses at Mossell Lake but E. nigrum was common in Mawson mossbeds. G. pannorum was widespread and colonised a range of different habitats, particularly in the Vestfold Hills. T. microsporus was also widespread particularly at sites frequented by birds and seals. Phialophora fastigiata was common around the stations, especially Davis Station, in soils including those contaminated with oil and in wood, and is thought to have been introduced with softwood packing crates. A greater range of taxa including Mortierella, Mucor, Penicillium and Cladosporium spp. was recorded from Mawson Station than from other sites, and this was attributed to the effects of human activity, Few fungi but a range of bacteria were isolated from the petroleum contaminated soils. A high percentage of these soils contained bacteria which could utilise hydrocarbons as a sole carbon source. Some of these bacteria showed a strong degradative potential, namely Flavobacterium spp., Corynebacterium spp., Bacterillus spp., and an isolate from the family Enterobacteriaceae. One isolate of Corynebacterium and the Enterobacteriaceae isolate were active hydrocarbon degraders at 1 degree C. Hormoconis resinae, the imperfect state of Amorphotheca resinae was only isolated from oil spill soils and then only from sites of recent spills. Geomyces pannorum and Thelebolus microsporus were less common in oil contaminated soils than in uncontaminated soils.

Quality Samples were collected in January and February 1988 from sites within Station confines, outside Davis and Mawson Station boundaries but within 2 km and from remote sites, Mossell Lake area in the Vestfold Hills and Rum Doodle in Mac Robertson Land. Although remote, these locations are visited by Station personnel and were therefore considered as low impact rather than pristine sites. ... Collections were made from raw mineral soils and from the different types of plant community present at each site. Petroleum contaminated soils were collected from spills made in 1986 and 1987, in January 1988 and from sites of continuous spillage. These included the 'fuel farms' which are areas set aside for fuel storage, and helipads where spills of aviation kerosene are common and sump oil is used to reduce dust levels. Wood was collected from packing crates imported between 1982 and 1988.
Soil samples were collected to a depth of 2 cm by scooping a sterile 2 cm diameter phial horizontally through the soil. Moss, lichen and algal samples were collected using sterile forceps or scalpels. The samples were kept at field temperatures for a maximum of 4 hours and then at -20 degrees C for return to Australia.
