Its holoblastic, monoblastic conidiogenesis (a method of spore production) and the absence of conidiophores further support its placement in Stagonospora.

The species is distinct from other fungal parasites on vascular plants, such as Stagonospora subseriata, due to its unique host association and morphological features.

[2] The fungus forms singular, immersed to semi-immersed fruiting bodies known as conidiomata, which are black, subglobose (nearly spherical), and measure 180–250 μm in diameter.

The infected portions of the host lichen show noticeable bleaching, transitioning from their typical glossy dark green coloration to a dull light brown.

In Bavaria, Germany, it has been recorded at three sites: a campground in Thalkirchen, Munich; a nearby area south of Hinterbrühl; and a pasture near Gut Hartschimmel at lake Ammersee.
