Notes: Recently (2009) documented from the North Cascades of Washington. It is sometimes confused with Lycopodium clavatum. FNA2: "Lycopodium lagopus is generally more northern than its sister species, L . clavatum. Where they come together, however, they can grow side by side (even in southern Michigan) and maintain their distinctions."
