One of the two smallest Vezdaea species in the Czech Republic. It has flat hexagonal apothecia and simple spores. The asci are wrapped in a loose net of tightly adpressed branched paraphyses. The goniocysts are only finely spinose in contrast to the similar V. rheocarpa. The two species are ecologically similar and macroscopically indistinguishable; they form pale pinkish gelatinous apothecia surrounded by scattered yellow-green globules resembling algae.
V. retigera is known from anthropogenic localities including contaminated toxic stands but may also be found at naturally disturbed sites. It colonizes a variety of substrates, mainly bryophytes, plant debris, humus, other lichens or tree bark. It is best found when wet during early spring.
