See text Verrucula is a genus of lichenicolous (lichen-dwelling) lichens in the family Verrucariaceae.
Verrucula was originally circumscribed in 1896 by Austrian lichenologist Julius Steiner to contain a group of parasitic Verrucaria species.
[3] Molecular phylogenetic analysis shows that Verrucula has a sister taxon relationship with Placocarpus in the family Verrucariaceae.
This is pycnidial type is characterised by its paraplectenchymatous net (paraplectenchyma is a fungal tissue with a cellular structure superficially like the parenchyma of vascular plants) and its multiple cavities.
