One of the two Vezdaea species with pale flat hexagonal apothecia and simple spores. The apothecia contain very short loose paraphyses and the ascospore surface is rough in contrast to the similar V. retigera which has smooth spores and long paraphyses tightly adpressed to the asci. It is well-recognizable even when sterile due to the characteristic goniocysts irregularly covered with horn-shaped spines, often even more than 5 µm long.
Similarly to its relatives, it grows on both natural and anthropogenic industrial substrates. In the Czech Republic, it is often collected on old dying thalli of Peltigera species. There are only few published records, but it is certainly an overlooked species.
