Taxonomy

Both the genus and its sole species species were introduced to science by the Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1857. He described the genus as follows: "Apothecia scattered, distinct, circular, shaped like a small dish, sessile and attached, bordered by its own carbonaceous cup-shaped margin, parasitising other lichens. The disc is always open, situated on a simple, very black hypothecium. The asci are club-shaped, eight-spored, mixed with paraphyses. The spores are ovoid-ellipsoidal, single-celled, transparent, with a colourless episporium and a simple nucleus."^[2]

As of 2017, there is no molecular sequence data available for this genus, and it remains poorly known. It is considered to be of uncertain (incertae sedis) placement in the order Lecanoromycetes.^[3][4]
