Kiliasia philippea (Mont.) Hafellner

A crustose microlichen resembling species of Lecidella in its habitus and Catillaria microscopically. Thallus is cracked to areolate, pale ochre brown to grey brown, sometimes also rusty, not pruinose. Its black lecideine apothecia are conspicuously dark on the cross-section due to densely pigmented hypothecium and contain one-septate, relatively wide ellipsoid spores.

It grows on calcareous rocks, mainly on limestone, from lowlands to mountains and prefers continental areas. The species is rare in the Czech Republic, only recorded on calcareous outcrops of Barrandien in south-western part of Prague (Servít 1910, 1930) where it has also been recently confirmed (Malíček et al. 2014).
