Ramalina calicaris (L.) Fr.
Thallus fruticose, tufted, erect to more or less pendant, with tough, flattened branches that have upturned margins, especially near the base, forming single channels, branch surfaces with minute, dot-like, white pseudocyphellae, soredia absent; apothecia frequent, rather button-like on the margins of the branches. Local in the north and west, very rare elsewhere, on nutrient-rich twigs and branches.
