Abstract: Ramalina implectens Nyl.; Mycobank #403741 Bull. Soc. linn. Normandie, sér. 2 4(2): 116 (1870) Type:― Husnot, Plantae Canarienses No. 214 (H-NYL37l72— lectotype; PC— isolectotype) (Krog & Østhagen 1980). Thallus fruticose, upright to pending, yellow-green to pale yellow, somewhat shiny, soft, consisting of 0.5–2 mm broad, reaching up to 14 cm in length. Lobes infrequent, compressed into channel-like structures with sharp, frequently curved tips, emerging from a shared base. Soredia absent. Pseudocyphellae usually present, short, inconspicuous, predominantly marginal. Apothecia common, marginal as well as subapical. Chemistry: Medulla spot tests K– or K+ yellow occasionally turning red, KC–, C–, P– or P+ yellowish-orange, UV– or UV+ white; TLC: Cortex usnic acid, medulla lacking lichen substances or salazinic, hypoprotocetraric, protocetraric, and/or norstictic acids (Krog & Østhagen 1980). Ecology and distribution: Ramalina implectens was recently discovered in Iran, and seems to prefer higher elevations. It occurs in the Macaronesian-Mediterranean area and the southern part of the Iberian Peninsula, including Majorca, Spain. There it grows on Quercus ilex, typically located on the boughs of perennial plants and bushes within exposed yet extremely damp settings in Tyrrhenian Italy (Krog & Østhagen 1980, Van Den Boom 1999, Nimis & Martellos 2024). Note: Ramalina implectens and R. farinacea are morphologically identical, except for the soralia present in R. farinacea. Otherwise, their anatomical characteristics are indistinguishable, and the medullary compounds of R. implectens are the same as in R. farinacea (Krog & Østhagen 1980). Specimens examined: Specimens examined: MAZANDARAN: Nour county, Donkoo village, 2 km towards Khvortab Rud, GPS: 51.910725N, 36.344940E, 1900 m., 9 November 2018, on the bark of a deciduous tree, M. Sohrabi & M. Ghobad-Nejhad & M. Mofid 30483 sub. R. pollinaria) (Herb. Sohrabi).
