Recorded distribution in Britain and IrelandWidely distributed around Britain and Ireland on rocky shores but not recorded from the shores of south east England, probably due to a lack of suitable substrata.
HabitatFound on well lit rocks from the middle to the lower shore. Rarer on wave sheltered shores.
- Thallus bright bottle-green to dark olive green in colour.
- Thallus bears a white margin (prothallus).
- Small, black fruiting bodies (perithecia) embedded in thallus when wet and raised when dry.
Additional informationMay be confused with Verrucaria maura or Verrucaria striatula. Verrucaria striatula is similar but bears elevated black dots or ridges and prominent black fruiting bodies. Verrucaria maura has a matt black, cracked encrusting thallus with numerous small black fruiting bodies and occurs from just below to above high water level.
