Prothallus not seen. Thallus pale grey, rimose to areolate, areoles 0.3-0.7 mm. Perithecia 0.22-0.26 mm, immersed in thallus. Involucrellum absent. Exciple wall pale. Periphysoids ca. 50-80 × 2.5-3 mm, branching. Ascospores 0-septate (only few seen), 20-28 × 13-14 mm.

Notes.

Krzewicka (2012) treated V. carnea as a pigment-deficient mutant of V. hochstetteri and Gilbert (1996) as an albino form of V. macrostoma Dufour ex DC. However, it differs in several morphological characters from these species. Oïhénart et al. (2018) accepted V. carnea as a distinct species.
