Sistotrema brinkmannii,a psychrotolerant fungus from Antarctic soil
一株源于南极土壤的耐冷真菌Sistotrema brinkmannii

A psychrotolerant fungus with clamp connections was isolated from soil obtained from the Lake Fryxell Basin in the Dry Valleys of Antarctica. Phylogenetic analysis using ITS sequences of rDNA indentified the fungus as Sistotrema brinkmannii. Cultures produced basidia with clamp connections at their base and 4 to 8 characteristic sterigmata as well as the suballantoid basidiospores. Few filamentous basidiomycetes have been found in Antarctica and the biology and ecology of this fungus needs additional investigation.
