Order: Peltigerales Family: Pannariaceae
Species: Degelia ligulata
Photos: On soil in coastal rock crevice. Eyries, Cork, SW Ireland.
Very similar to D. atlantica and D. plumbea but with numerous elongate schizidia (flattened to spoon-shaped isidia). Schizidia often blackened at tips. Apothecia are very rare, the discs brown to black. Part of Macaronesian element in British and Irish lichen flora.
Occurs in rock crevices, on soil and occasionally at base of coastal trees and shrubs. Rare, mainly found on north-western Irish coasts. Chemical reactions negative.
