Note on a snow mold and a fungus-like microbe from Kuujjuarapik-Whapmagoostui, Quebec, subarctic Canada

Description
Summary:An isolate of a novel fungus and an isolate of a novel fungus-like microbe were obtained during field research conducted in Kuujjuarapik-Whapmagoostui, Quebec, in subarctic Canada, located on the southeastern coast of Hudson Bay, from August to September 2016. The isolates were identified as a Typhula sp. and Globisporangium sp. (syn. Pythium sp.), respectively. Mycelia with clamps connections were isolated from small sclerotia (0.2–0.7 × 0.5–1.2 mm in size) collected from dead leaves of sea pea (Lathyrus japonicus) on the banks of the Great Whale River in Kuujjuarapik-Whapmagoostui. The isolate was found to be closely related with T. japonica based on sclerotium morphology and hyphal growth under different temperatures. The Globisporangium sp. isolate was found to be most closely related to G. okanoganense based on phylogenetic analyses using rDNAITS. G. okanoganense is known as an important pathogen causing snow rot on wheat and other winter crops. Further investigation is needed to determine whether the novel fungus and fungus-like microbe found in Kuujjuarapik-Whapmagoostui are phytopathogenic like the snow rot pathogens to which they are closely related.
