Ramalina “neopacifica” ined.: known from wet, coastal forests, this species it not confirmed for Alberta. It is longer and wider than R. dilacerata (14 mm on average to 41 mm tall x 28 mm on average to 45 mm wide, Hampton-Miller 2012) and appears ‘leggier’. Molecular work is required to verify its presence. Ramalina sinensis: larger thalli, with solid, flattened branched with conspicuous pseudocyphellae. |
