Squamulea (including Huriella )

Only one species recorded in the region. Thallus is crustose, formed of small squamules. Vegetative diaspores are absent; apothecia are present. It is confined to inorganic substrates. Literature: Arup et al. (2013), Kondratyuk et al. (2017).

Squamulea sp. , Fig. 5D : Only one specimen recorded at altitude 660 m (Vondrák 18682), in arid non-alpine habitat. Substrate: vertical side of sandstone outcrop in steppe. Specimen is morphologically similar to the European Squamulea subsoluta (ITS similarity 91–92%), but its ITS sequence is closer to two species from the Far East: Huriella loekesiana (95–96% similarity) and Squamulea sp. (KJ133481, 98% similarity).
