Typification and emendation of Seirophora Poelt to include species segregated from Teloschistes Norman

• The type material of Physcia magara Kremp., which is the type species of Seirophora Poelt (Teloschistaceae), is shown to be heterogeneous. It is a mixture of Teloschistes villosus (Ach.) Norman and Ramalina maciformis (Delile) Bory. Physcia magara Kremp. is typified on the T. villosus-part. Teloschistes species with multiseriate hairs, spores with short septa, thick and strongly conglutinated cortex hyphae with thick walls, lacking cilia or rhizines, and which have a mainly northern hemispheric distribution, are transferred to Seirophora. The following new combinations are made: Seirophora aurantiaca (R. Br.) Froden, Seirophora austroarabica (Sipman) Froden, Seirophora californica (Sipman) Froden, Seirophora contortuplicata (Ach.) Froden, Seirophora lacunosa (Rupr.) Froden, Seirophora scorigena (Mont.) Froden, Seirophora stenophylla (Tav.) Froden, and Seirophora villosa (Ach.) Froden.
