Phacographa protoparmeliae Hafellner, 2009

Phacographa protoparmeliae Hafellner. Bibl. Lich. 100: 106. 2009.

Holotype.

AUSTRIA, Kärnten: Hohe Tauern, Kreuzeck-Gruppe, Kalkschieferwände in den SE-Hängen der Sensenspitze N der Turgger Alm, c. 200 m. 17 July 1978, Hafellner 603 ( GZU).

Distribution.

New to the Nordic countries. Phacographa was described by Hafellner 2009 who included three species in the genus. It belongs in the newly described family Lecanographaceae within the Arthoniales ( Frisch et al. 2014). Phacographa protoparmeliae (Fig. 9 ) was originally reported from Austria and Spain ( Hafellner 2009), and a specimen was later discovered in the Murmansk region in arctic Russia ( Fryday 2011). Here we report it for the first time from the Nordic countries from two localities in Norway. Both are at old copper mines in subalpine habitats in the mining district of Røros in central Norway.

Phacographa protoparmeliae (Fig. 9 ) is a lichenicolous fungus growing on the common and widespread saxicolous lichen Protoparmelia badia . The apothecia of Phacographa have a black margin around a dark brown disc; they are up to 1.2 mm wide in the Norwegian material and form clustered groups of 2-6 apothecia. Microscopically it is characterized by its 3-septate, spores, 22-25 × 6-7(-8) µm that are colourless but have a perispore sheath that becomes brown with age. More detailed descriptions can be found in Hafellner (2009) and Fryday (2011).
