Description: This species will strike beginners as resembling Ochrolechia parella (described elsewhere) growing on bark. O. parella can indeed sometimes grow on bark, but in certain places in the north-west of Ireland such occurrences should be regarded with suspicion, as it may be this species which has a thinner thallus and fewer, evenly scattered discs. It is even more likely to be this species if recorded from smooth-barked trees such as alder, birch and willow in moist, swampy woodlands. Western Donegal appears to be its main headquarters.

Key Identification Features:

• Like O. parella but with a thinner thallus growing on bark
• On smooth-barked trees in swampy woodland in the north-west.
