Lobaria macaronesica Cornejo & Scheidegger

     This species, formerly pro parte described under Lobaria pulmonaria var. meridionalis was recently individualized. Differs from Lobaria pulmonaria var. pulmonaria by (i) the absence of isidioid soralia, (ii) the presence of long isidia, simple, terete or coralloid at lobes margin. Endemic to Macaronesian Islands. N.B. Lobaria pulmonaria var. meridionalis ss. auct. eur. is only an ecoform of Lobaria pulmonaria var. pulmonaria without isidiomporphs and with short terete isidia. Also endemic to Macaronesian Islands, Lobaria immixta has flattened isidia towards lobes margin.
