Peltigera cinnamomea Goward is described as new, and the blue-green phototype of Peltigera leucophlebia (Nyl.) Gyelnik is documented for the first time. Peltigera scabrosella Holt.-Hartw. is reported as new for North America based on a collection from the Yukon Territory. Peltigera hymenina is new for British Columbia. Key words: lichens, Ascomycotina, Peltigera, Peltigeraceae, British Columbia, distribution.
