[2] The genus was established by Amanda Xavier-Leite, Marcela Cáceres, and Robert Lücking, and is named in honour of Antonín Vězda, a prominent 20th-century lichenologist who greatly scientific understanding of leaf-dwelling (foliicolous) lichens, particularly in the family Gomphillaceae.

It was first described in Lopadium (1881), then moved to Tricharia, later to Actinoplaca, and then to Gyalideopsis, before finally being recognised as its own distinct genus through modern genetic analysis.

[3] These lichens form a continuous, finely warty layer on leaf surfaces, but unlike some related genera, they lack bristles on their main body.

Their reproductive structures (apothecia) sit directly on or slightly above the surface and have a distinctive yellowish-green centre with a yellow or white-frosted rim.

Under the microscope, each reproductive structure produces just a single large ascospore that is divided into multiple compartments both lengthwise and crosswise (muriform).
