Blight of moss caused by Pythium sp. in Greenland

Pythium sp. actively attacks mosses (Sanionia uncinata) growing in Kangerlussuaq, Ammassalik, Kulusuk, and Ittoqqortoormiit, Greenland. This is the first report of the occurrence of Pythium moss blight in Greenland. All isolates from Greenland could grow at o ° C, and the mycelial growth rate of isolates from Greenland, compared with that of isolates from the Temperate Zone, were very low at temperatures above 10°C. However, the optimal growth temperature of Greenlandic isolates was the same as that of isolates from the Temperate Zone. These results suggest that isolates of Greenland originally developed from isolates from the Temperate Zone and adapted to growth under Arctic conditions

New findings of snow mold fungi from Greenland

Three species of snow mold fungi, Myriosclerotinia borealis (syn. Sclerotinia borealis), Typhula incarnata and T. ishikariensis (syn. T. borealis), were collected from Nuuk, Sisimiut, Ammassalik and Kulusuk in Greenland. Myriosclerotinia borealis and T. incarnata are new records from Greenland. Some isolates of T. ishikariensis were collected from Nuuk and Ammassalik and all isolates from Sisimiut showed irregular growth as hyphal extensions at 10°C in potato dextrose agar plates. These physiological characteristics of some isolates from Greenland are similar to those of psychrotrophisolates (group III strains) from Finnmark, northernmost Norway and Svalbard

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, 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
