| Preferred label | [Verrucaria maura] on littoral fringe rock |
| Definition | Bedrock or stable boulders and cobbles in the littoral fringe which is covered by the black lichen [Verrucaria maura]. This lichen typically covers the entire rock surface giving a distinct black band in the upper littoral fringe. The winkle [Littorina saxatilis] is usually present. Two variants are defined which both occur in a wide range of wave exposures. On exposed shores [V. maura] may occur with sparse barnacles such as [Chthamalus] spp. or [Semibalanus balanoides] and may be covered by a band of ephemeral seaweeds such as [Porphyra umbilicalis] or [Enteromorpha] spp. (Ver.B). Above Ver.B or on more sheltered shores is a species poor community consisting mainly of [V. maura] and [L. saxatilis] (Ver.Ver). Situation: This biotope occurs below the yellow and grey lichen zone (YG) and above eulittoral communities of barnacles and fuciod algae. Temporal variation: Distinct band of red or green ephemeral algae may obscure the black lichen band at certain times of the year. |
