G. bicincta G. carpinea G. leptyrodes G. lojkaeana G. rupicola G. subcarpinea G. swartzii Glaucomaria is a genus of lichen-forming fungi in the family Lecanoraceae.

The apothecia (fruiting bodies) initially grow attached (adnate) and can become slightly raised (sessile) or nearly stalked (substipitate).

These apothecia feature a heavily powdery (pruinose) disc that reacts to the C spot test to produce an intense lemon-yellow colour.

The margin of the apothecia is persistent, sometimes being pushed aside (finally excluded), and occasionally surrounded by a black, wavy (flexuose) ring.

The inner layer (proper exciple) ranges from thin to thick, dark on the outside and upper part but colourless inside.
