Abstract

Fifteen species of the Caliciales are reported from Africa and Macaronesia. Calicium subquercinum, Chaenotheca chrysocephala, Ch. trichialis, Coniocybe furfuracea, C. gracillima, Sphinctrinella calicioides and Tylophoron protrudem are new to Africa; Calicium trabinellum and Strongyleuma exsertum are new to Macaronesia.

The species belong to two groups with respect to their distribution: (1) the borealtemperate species with a wide distribution in the Northern Hemisphere, such as Chaenotheca chrysocephala and Ch. trichialis, occur only at high elevations, usually about or above 3000 m; (2) one including, for example, Tylophoron moderatum, T. protrudens and Schistophoron—species occurring at low or moderately high elevations with a subtropical/tropical distribution.
