Gyalolechia sensu lato

7 species recorded in the region.All are crustose, often with thick thallus. Vegetative diaspores are present (4 species) or absent. Apothecia are known in all species, but rare in some species with vegetative diaspores (e.g. Gyalolechia lenae ). Gyalolechia was defined in a broad sense by Arup et al. (2013) and subdivided into smaller genera by Kondratyuk et al. (2014 a, 2017). We adopted the broad concept of the genus, but group the species into three infrageneric sections corresponding to Kondratyuk’s small genera: (1) Gyalolechia sensu stricto including soil inhabiting lichens formerly placed in Fulgensia , (2) Mikhtomia , a group of species similar to Gyalolechia flavorubescens and (3) Hanstrassia , a group of thick xerophilous crustose lichens from continental Asia. Literature: Arup et al. (2013), Kondratyuk et al. (2014 a, 2017), Søchting & Figueras (2007).

Gyalolechia bracteata (section Gyalolechia ): 3 localities at altitudes 850–1750 m, in arid ecological classes. Substrate: calcareous soil, weathered limestone.

Gyalolechia epiphyta (section Mikhtomia ): 5 localities at altitudes 1400–2900 m, mostly in arid ecological classes. Substrate: various types of inorganic and organic substrates; base-rich siliceous rock, calciphilous bryophytes, bark of Populus in dry sites. Additional information in Vondrák et al. (2016a).

Gyalolechia flavorubescens (section Mikhtomia ): 4 localities at altitudes 500–1000 m, in humid non-alpine ecological class. Substrate: bark of Populus , Sorbus .

Gyalolechia flavovirescens (section Mikhtomia ): 20 localities at altitudes 250–1750 m, in humid and arid non-alpine ecological classes plus single record in dry alpine class. Substrate: calcareous and base-rich rock (e.g. schist, gneiss).

Gyalolechia fulgens (section Gyalolechia ): 3 localities at altitudes 250–850 m, in arid non-alpine steppes. Substrate: calcareous soil, loess.

Gyalolechia lenae (section Hanstrassia ): 19 localities at altitudes 400–2900 m, most records from arid alpine and non-alpine habitats and exceptionally in humid ecological class. Substrate: limestone, less frequently base-rich siliceous rocks.

Gyalolechia ussuriensis (section Mikhtomia ): 9 localities at altitudes 430–820 m, in arid and humid non-alpine classes. Substrate: bark of Juniperus sabina , Larix , Populus , Salix . Additional information in Vondrák et al. (2016a).
