Non‐geniculate coralline algae are difficult to identify based solely on morpho‐anatomy. To address the systematics of several taxonomically challenging taxa, we analyzed DNA sequences of a short portion (118‐296 base pairs) of the 3’ end of the rbcL gene from three type specimens. The analyses revealed that Harveylithon munitum (basionym: Lithophy...
