Ramalina maciformis (Delile) Bory (expected to be in South of Iran); Mycobank #403769

Dict. Class. Hist. Nat. 14: 458 (1828). ― Parmelia maciformis Delile 1813 .

Type: ― Egypt, Moqattam, entre les fentes Ces rochers derridre la citadelle du Kaire’ (not seen) ( Krog & Osthagen 1980).

Thallus more or less articulately ridged, producing coarsely granular or corticate granules (over 100 µm in diameter) in ulcerate areas; chondroid layer dissolved in separate strings embedded in dense medulla and surrounded by thick cortex. Apothecia not seen.

Chemistry: Medulla spot tests K–, C–, KC_, PD–, UV–; medulla KC–; TLC: bourgeanic acid with or without salazinic or norstictic acids.

Known mainly from North Africa, it is also found along the oceanic coast of the Arabian Peninsula in Bahrain Al- Thani et al. (2011) and therefore expected on the oceanic coast of Iran. The report by Szatala (1957) from Iran is based on the Bahraini specimens, which were part of the Iranian administrative border at that time. This species is expected to be in the Persian Gulf coastal zone.
