LICHALP

Synalissa ramulosa (Hoffm. ex Bernh.) Fr.

Syn.: Collema ramulosum Hoffm. ex Bernh., Collema synalyssum (Ach.) Ach., Lichen symphoreus Ach., Synalissa symphorea auct. non (Ach.) Nyl.

Lichenised.

Substrate: calciferous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a mainly southern species in Europe, found on steeply inclined faces of calcareous rocks with periodical water seepage, often overgrowing the thalli of Romjularia lurida, with a wide altitudinal range, but with optimum at relatively low elevations; widespread throughout the Alps.
