The more common of the two Czech terricolous arctic-alpine Alectoria species. It differs from A. nigricans in the yellow-green colour and chemically (it contains usnic and diffractaic acids). Its overall range covers Europe, Asia, both Americas and Antarctica. In the Czech Republic, the lichen grows in the highest mountains of the Bohemian massif (the Šumava, Krkonoše, Králický Snežník and Hrubý Jeseník Mts). It may be found mainly in wind-exposed places with sparse vegetation above the upper tree line, in screes also lower. More of its recent localities are known from the Krkonoše Mts. Interesting is its presence in inverse sandstone ravines in the Adršpach-Teplice rock complex.
