Cypheliopsis mediterranea (B. de Lesd.) Nádv.

Stud. Bot. Čechoslov., 5: 126, 1942. Basionym: Cyphelium mediterraneum B. de Lesd - in Crozals, Ann. Soc. Hist. nat. Toulon, 10: 90, 1924

Distribution:

Description: Thallus crustose, episubstratic, rather thick, white to grey-white, areolate-verrucose, the sterile areoles flat and smooth, the fertile ones convex, sometimes almost conical, with crenulate-sinuose margins. Medulla white, I-. Apothecia 1-2 mm across, developing on the fertile areoles, with an epruinose, black mass of spores (mazaedium) accumulating on the disc; hypothecium pale brown. Ascopores 1-celled, dark brown to almost black, grobose or subglobose, 10-15 μm wide, with a verrucose wall. Photobiont chylorococcoid. Spot tests: K-, C-, KC-, P-. Chemistry: probably without lichen substances.

Note: A very poorly known silicicolous species growing on more or less coastal rocks subject to humid maritime winds, recorded from two stations only, one of which is in Corsica. The species is practically identical to Thelomma siliceum and has a similar ecology, differing in the negative reaction to C. It probably should be transferred to Thelomma, and the relation with Th. siliceum is worthy of further study. To be looked for in Tyrrhenian Italy.

Growth form: Crustose

Substrata: rocks

Photobiont: green algae other than Trentepohlia

Reproductive strategy: mainly sexual

Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)

Poorly known taxon in need of further study
