Borovichev E.A. Botanical excursion on the Northern Soroya. Hammerfest, 2014.

Lichens on upper geolittoral Lichens here are not flooded but during storms they are exposed to the action o f waves and sea spray, and sometimes get covered by the high tidewater. Moreover, these habitats and lichens often are fertilized by birds’ droppings and it’s why they are called “ornithophilous”. Lichens-specialists o f upper geolittoral rarely occur at some distance from the shore in habitats visited by birds; among them, Amandineu coniops and Xanthoria elegans are the commonest. Caloplaca microthallina (yellow) and Verrucaria Leeanora actophila occurs in holes in stone maura (black) Leeanora poliophaea is rarer in the Soroya than the previous species 92
