A filamentous fungus, Pythium ultimum TROW var. ultimum, isolated from moribund moss colonies from Svalbard, northern islands of Norway

A fungus, Pythium ultimum TROW var. ultimum, was isolated from colonies of moribund moss, Sanionia uncinata (HEDW.) LOESKE, in Svalbard. This is the first report of isolation of P. ultimum var. ultimum from the Arctic Zone. This fungus showed possible moss pathogenic activity. The taxonomic, morphol...

Description
Summary:A fungus, Pythium ultimum TROW var. ultimum, was isolated from colonies of moribund moss, Sanionia uncinata (HEDW.) LOESKE, in Svalbard. This is the first report of isolation of P. ultimum var. ultimum from the Arctic Zone. This fungus showed possible moss pathogenic activity. The taxonomic, morphological and ecological characteristics are described here. In addition, the mycelial growth of this isolate is compared with that of isolates from the Temperate Zone, and its physiological characteristics are discussed.
