LICHALP

Thelocarpon laureri (Flot.) Nyl.

Syn.: Sphaeropsis laureri Flot., Thelocarpon epilithellum Nyl., Thelocarpon interceptum Nyl., Thelocarpon prasinellum Nyl.

Lichenised.

Substrate: acidic soil (mostly on siliceous substrata), siliceous rocks, lignum, living mosses

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: an ephemeral early coloniser of different substrata, including roofing tiles, rotten wood, and soil; perhaps more widespread in the Alps, but very much overlooked.
