Forked Veilwort - Metzgeria furcata

    Description

    This thallose species forms yellowish green patches on trunks and larger branches. The thalli that are just over 1 mm wide, and possess a thick, strongly contrasting midrib and a forked tip. The margins are flat or slightly down curved with a line of scattered hairs. Inflorescences can be found on the underside of most patches, but sporophytes are only occasional. Narrow, almost linear gemmae are sometimes found on the thallus margins.

    Habitat

    Bark of a wide range of trees and shrubs, including ash (Fraxinus excelsior), sycamore (Acer pseudoplatanus) and willow (Salix). Occasionally on rocks, walls or graves, especially in western districts.
