Pythium polare, a new heterothallic Oomycete causing brown discoloration of Sanionia uncinata in the Arctic and Antarctic
Pythium polare sp. nov. is a new heterothallic oomycete species isolated from fresh water and moss from various locations in both the Arctic and Antarctic. This water mould is able to infect stems and leaves of Sanionia moss (Sanionia uncinata). Pythium polare causes brown discolouration in in vitro...
