Physconia jacutica

Physconia jacutica is a species of saxicolous (rock-dwelling), foliose lichen in the family Physciaceae.

The type specimen was collected on the bank of the Lena River near Elanka (Khangalasskiy Ulus, Sakha Republic) at an altitude of about 100 m (330 ft).

There the lichen was found growing abundantly on rocks at the base of a dolomitic cliff from the Cambrian.

The authors note that among the high dolomite cliffs, the lichen "is so abundant that it gives a bluish-white tint to the whole landscape".

[2] Molecular phylogenetic analysis suggests that P. jacutica groups together in a clade with P. grumosa, P. lecuoleiptes, P. kurokawae, and P. muscigena.
